The Loess Plateau: Preserving the Most Complete Sequence of Chinese Civilization
黄土高原：存续中华文明最完整的序列
The Loess Plateau: Preserving the Most Complete Sequence of Chinese Civilization

引言
Introduction
在《旋回：空间哲学及其规划实践》所构建的宏大叙事中，黄土高原占据着一个极为特殊的位置。它不是文明的起点，也不是终点，而是一个枢纽，四方文化在此汇聚、碰撞、融合，最终淬炼出中华文明的初代形态。从三皇五帝到三代九朝，从暖期的文明累积到冷期的石城防御，这片土地承载了中华文明在第二阶梯上最为完整、最为深厚的历史记忆。在中华大地的所有地理单元中，黄土高原存续着人类文明演进最完整的序列，从旧石器时代的西侯度遗址到新石器时代的大地湾、仰韶，从龙山时代的陶寺、石峁到青铜时代的二里头、殷墟，再到秦汉隋唐、宋元明清，文化的延续从未中断，序列的完整举世罕见。
In the grand narrative of Xuanhui: A Philosophy of Space and Its Planning Practice, the Loess Plateau occupies an exceptional position. It is neither the origin nor the endpoint of civilization but a pivot: cultures from all directions converge, collide, and fuse here, and it is here that the earliest form of Chinese civilization was forged. From the Three Sovereigns and Five Emperors to the Three Dynasties and Nine Reigns, from the civilizational accumulation of warm periods to the stone-city defense of cold periods, this land bears the most complete and profound historical memory of Chinese civilization on the Second Step. Among all geographic units of the Chinese land, the Loess Plateau preserves the most complete sequence of human civilizational evolution—from Xihoudu in the Paleolithic, to Dadiwan and Yangshao in the Neolithic, from Taosi and Shimao in the Longshan era, to Erlitou and Yinxu in the Bronze Age, and on to Qin-Han, Sui-Tang, Song-Yuan, and Ming-Qing. Its cultural continuity has never been interrupted; the completeness of its sequence is rare in the world.
安芷生院士用半个世纪的研究，在黄土高原的地层中读出了地球气候的“旋回”密码，西北风与东南季风的交替进退，黄土与古土壤的层层叠压，记录着数百万年来冷暖更迭的宏大节律。这片土地本身就是一部读不完的书。
Academician An Zhisheng, through half a century of research, has read the code of climatic “cyclical return” from the strata of the Loess Plateau. The alternating advance and retreat of the northwest wind and the southeast monsoon, the layer upon layer of loess and paleosol—they record the grand rhythm of cold and warmth over millions of years. This land is itself an unfinished book.
理解黄土高原，就是理解中华文明如何在不断的“旋回”与“自洽”中，从多元走向一体，从第二阶梯走向整个东亚大陆。
To understand the Loess Plateau is to understand how Chinese civilization, through ceaseless “cyclical return” and “self-consistency,” moved from diversity to unity, from the Second Step to the whole of the East Asian continent.
01 第二阶梯的腹地
01 The Hinterland of the Second Step
在“天地矩阵”的框架中，黄土高原地处中国第二阶梯的腹地，是九宫格地缘结构的核心枢纽。它覆盖了陇东高原、陕北高原、关中盆地和晋西南谷地，面积广阔、地形多样。北纬35度左右的黄河一线，正是书中反复论证的“人类最舒适区域”。从气候条件来看，这里冷暖变化相对温和，既不像青藏高原那样高寒，也不像沿海低地那样饱受海侵威胁。从地缘条件来看，它西接青藏高原，北临蒙古高原，东连华北平原，黄河穿流而过，是连接第一阶梯与第三阶梯的战略枢纽。它同时也是环青藏高原大通道的东端汇聚点，羌北道、羌中道、羌南道三条主干线由此分岔或汇聚，使黄土高原成为四方文明因素从“传入”走向“内化”的转换器。
Within the framework of the “Heaven-Earth matrix,” the Loess Plateau lies in the hinterland of China’s Second Step, the core pivot of the Nine-Palace geographic structure. It covers the Longdong Plateau, the Northern Shaanxi Plateau, the Guanzhong Basin, and the valleys of southwestern Shanxi—vast in area and diverse in terrain. The Yellow River line at roughly 35° north latitude is precisely the “most comfortable zone for humanity” that the book repeatedly demonstrates. Climatically, cold and warmth here vary relatively gently—neither as frigid as the Qinghai-Tibet Plateau, nor as exposed to transgression as the coastal lowlands. Geographically, it borders the Qinghai-Tibet Plateau to the west, the Mongolian Plateau to the north, and the North China Plain to the east, with the Yellow River running through it—a strategic pivot between the First and Third Steps. It is also the eastern convergence point of the Great Corridor around the Qinghai-Tibet Plateau: the three main lines of the Northern, Central, and Southern Qiang Routes diverge or converge here, making the Loess Plateau a converter through which civilizational factors from all directions pass from “introduction” to “internalization.”
在“天地矩阵”中，黄土高原恰好位于四大流域线与四大阶梯线的交汇地带。东西向的黄河线横贯其腹地，西辽河-塔里木河线在其北方，长江线在其南方，珠江线通过西南线路与沿海线路与之相连。南北向的四条阶梯线中，第二阶梯线恰好贯穿黄土高原，第三阶梯线在其东缘，第一阶梯线在其西侧。这种“居中”的地理位置，使黄土高原同时接收来自东、南、西、北四个方向的文明输入。当暖期到来时，南方和东方的文明因素沿流域线逆流而上，汇聚于此；当冷期降临时，北方和西方的游牧力量沿阶梯线南下，在此与农耕文明碰撞。每一次汇聚和碰撞，都在黄土高原上留下新的文化层位。关中盆地作为黄土高原最精华的部分，八百里秦川地势平坦、水源充沛，被《周礼》称为“天下之上腴”，是中华文明核心区中唯一同时具备“居中、高亢、沃野、四塞”四个条件的地理单元。
In the “Heaven-Earth matrix,” the Loess Plateau lies precisely where the four river basin lines and the four step lines intersect. The east-west Yellow River line runs through its hinterland; the Xiliao-Tarim line lies to its north; the Yangtze line to its south; the Pearl River line connects to it through the southwestern and coastal routes. Among the four north-south step lines, the Second Step line runs straight through the Loess Plateau, the Third Step line lies at its eastern edge, the First Step line at its western side. This “central” position allows the Loess Plateau to receive civilizational input from east, south, west, and north at once. When warm periods arrive, civilizational factors from the south and east travel upstream along the basin lines and gather here; when cold periods descend, nomadic forces from the north and west move south along the step lines and collide with agrarian civilization here. Every convergence and collision leaves a new cultural layer on the Loess Plateau. The Guanzhong Basin, the most essential part of the Loess Plateau, with the flat and well-watered Eight-Hundred-Li Qin Plain, was called by the Rites of Zhou the “finest fertile land under heaven.” It is the only geographic unit in the core zone of Chinese civilization that simultaneously possesses the four conditions of centrality, elevation, fertility, and four-side enclosure.
书中提出，北纬中段25至40度是“人类活动相对安定的15度”，而黄土高原正处于北纬30至35度、海拔1000至1500米区间，这是“人类生存舒适度最好也是生存时间轴最长的区域”。距今8200至5400年前的大暖期鼎盛阶段，这里年均气温比今天高出2至3摄氏度，降水多出三分之一，温润的气候造就了大批良田，为文明的孕育提供了丰厚的物质基础。
The book proposes that between 25° and 40° north latitude lies a “relatively stable 15-degree zone of human activity.” The Loess Plateau sits precisely between 30° and 35° north latitude, at 1,000 to 1,500 meters above sea level—the “zone of greatest human comfort and the longest axis of human survival.” During the peak of the great warm period, 8,200 to 5,400 years ago, the annual average temperature here was 2–3°C higher than today, with one-third more precipitation. The mild climate produced vast fertile fields and provided a rich material foundation for the gestation of civilization.
黄土高原的黄土沉积本身也塑造了这片土地的独特性。黄土颗粒细腻，孔隙发达，具有垂直节理发育的特征，即使降水稀少也能使土壤保持一定的水分，为早期农业提供了得天独厚的条件。同时，黄土质地疏松，易于挖掘，先民得以在黄土台塬上挖掘窑洞、建造半地穴式房屋，形成聚落。这种“土生万物”的物质基础，使黄土高原成为中华文明最早的家园。
The loess deposit itself shaped the uniqueness of this land. Loess particles are fine and porous, with vertical jointing; even under sparse rainfall, the soil retains some moisture—an exceptional condition for early agriculture. Loess is also loose and easy to dig. The ancestors could excavate cave dwellings and build semi-subterranean houses on the loess tablelands, forming settlements. This material foundation of “earth giving birth to all things” made the Loess Plateau the earliest homeland of Chinese civilization.
世代先民在暖期向西向北迁徙，在冷期向东南退至低海拔平原，这种“旋回”能力使文明不必在单一气候条件下“一次性”地承受冲击。它不是边缘，而是中心；不是通道，而是熔炉。
Generation after generation, the ancestors migrated west and north in warm periods and retreated southeast to the low-altitude plains in cold periods. This capacity for “cyclical return” meant that civilization did not have to absorb the impact of a single climatic condition all at once. It is not a margin but a center; not a corridor but a furnace.
02 黄土与季风
02 Loess and Monsoon
黄土高原的地层本身就是一部无言的史书。安芷生院士及其团队用半个多世纪的研究，揭开了这部史书的核心密码。
The strata of the Loess Plateau are themselves a silent history book. Academician An Zhisheng and his team, through more than half a century of research, have unlocked its core code.
上世纪60年代，安芷生接续中国黄土研究的学术传统，将目光锁定在看似贫瘠却蕴含无尽奥秘的黄土高原。他意识到，要理解气候变化的规律，时间和年代的概念至关重要，没有精准的年代坐标，研究就会缺失方向。正是这种对“地质时钟”的执着追求，最终催生出“东亚季风变迁三旋回”理论。
In the 1960s, An Zhisheng took up the academic tradition of Chinese loess research, fixing his gaze on the Loess Plateau—seemingly barren, yet endlessly mysterious. He realized that to understand the laws of climatic change, time and chronology were crucial; without precise chronological coordinates, research would lose its direction. It was this persistent pursuit of the “geological clock” that ultimately gave rise to the theory of “Three Cyclical Returns of East Asian Monsoon Change.”
上世纪90年代初，安芷生率先提出中国黄土-古土壤序列记录了东亚冬、夏季风气候变迁历史的新思想，进而总结出“东亚环境变化的季风控制理论”。该理论完美破解了黄土-古土壤序列形成之谜：黄土代表冬季风占优势的干冷期，古土壤代表夏季风占优势的暖湿期，两者交替出现，构成数百万年的气候旋回。西北风与东南季风的交替进退，正是“旋回”二字在东亚大地上的物理呈现。每一层黄土都是冬季风从西北荒漠吹来的粉尘堆积，每一层古土壤都是夏季风带来的暖湿气候下植被生长的痕迹。安芷生及其团队将中国黄土与深海沉积序列成功对比，重建了黄土高原的气候历史，建立了最近240万年、13万年和2万年以来中国古环境变化序列。
In the early 1990s, An Zhisheng was the first to propose the idea that the Chinese loess-paleosol sequence records the history of East Asian winter and summer monsoon climatic change, and went on to formulate the “monsoon control theory of East Asian environmental change.” The theory solved the mystery of the loess-paleosol sequence: loess represents dry-cold periods dominated by the winter monsoon, paleosol represents warm-humid periods dominated by the summer monsoon, and the two alternate to constitute millions of years of climatic cyclical return. The alternating advance and retreat of the northwest wind and the southeast monsoon is precisely the physical manifestation of “cyclical return” on East Asian soil. Each layer of loess is dust carried by the winter monsoon from the northwestern deserts; each layer of paleosol is the trace of vegetation under the warm-humid climate brought by the summer monsoon. An Zhisheng and his team successfully correlated Chinese loess with deep-sea sediment sequences, reconstructed the climatic history of the Loess Plateau, and established sequences of Chinese paleoenvironmental change for the last 2.4 million, 130,000, and 20,000 years.
洛川黄土剖面是这一序列的典型代表。厚达130余米的黄土堆积，记录了第四纪以来数十次冷暖交替。剖面上黄土与古土壤交替出现，层次分明，如同一页页被翻开的地球日记，每一层都蕴含着古生物化石、孢粉组合、磁化率变化等环境信息。洛川剖面的黄土-古土壤序列中，磁化率曲线记录了最近250万年气候变化的历史，与深海沉积的气候记录可以精确对比，证实了黄土沉积记录全球性气候变化的可靠性。正是通过对洛川剖面数十年如一日的精细研究，安芷生团队才得以建立起中国黄土在全球气候研究中的“标准地层”地位。
The Luochuan loess section is a typical representative of this sequence. More than 130 meters of loess deposit record dozens of cold-warm alternations since the Quaternary. Loess and paleosol alternate on the section, clearly stratified, like pages of Earth’s diary turned open, each layer carrying environmental information—paleontological fossils, sporopollen assemblages, magnetic susceptibility changes. In the loess-paleosol sequence at Luochuan, the magnetic susceptibility curve records the history of climatic change over the last 2.5 million years, and it can be precisely correlated with deep-sea climatic records—confirming the reliability of loess deposits as records of global climatic change. It was through decades of meticulous research on the Luochuan section that An Zhisheng’s team established Chinese loess as a “standard stratigraphic” reference in global climate research.
安芷生突破了经典的全球冰期-间冰期理论，首次系统提出东亚环境变化的季风控制学说，揭示了南北半球冰量变化对亚洲季风的影响以及季风和西风气候在冰期旋回和千年尺度上的关系。通过中国黄土研究，中国黄土与深海沉积、极地冰芯一起成为全球气候变化研究的三大支柱。2023年，团队在《Science》发表论文，通过黄土序列发现了120万年前全球气候周期从4万年转向10万年的关键证据，这是中国科学家首次在该领域取得国际认可的突破。
An Zhisheng broke through the classic global glacial-interglacial theory and was the first to systematically propose the monsoon control doctrine of East Asian environmental change, revealing how hemispheric ice volume changes affect the Asian monsoon and how monsoon and westerly climates relate at glacial cyclical-return and millennial scales. Through Chinese loess research, Chinese loess has become one of the three pillars of global climatic change research, alongside deep-sea sediments and polar ice cores. In 2023, the team published a paper in Science reporting key evidence from loess sequences that the global climatic cycle shifted from 40,000 to 100,000 years around 1.2 million years ago—the first breakthrough by Chinese scientists in this field to gain international recognition.
安芷生常说：“每粒黄土都是地球写的日记，我们的任务就是读懂这些日记里的气候密码。”在纪元后小冰期，黄土甚至越过了台湾海峡，沉积在大鬼湖湖底。气候的每一次冷暖交替，都对应着文明的一次重组。暖期时，黄土高原成为人口聚集、文化繁荣的中心；冷期时，北方游牧力量南下，先民退守高地、筑城自固。
An Zhisheng often says: “Every grain of loess is a diary written by the Earth; our task is to read the climatic code within these diaries.” During the post-Common Era Little Ice Age, loess even crossed the Taiwan Strait and settled on the bottom of Daguihu Lake. Every alternation of cold and warmth corresponds to a reorganization of civilization. In warm periods, the Loess Plateau becomes a center of population aggregation and cultural prosperity; in cold periods, northern nomadic forces move south, and the ancestors retreat to high ground and build cities for self-defense.
理解气候“旋回”的节奏，就能理解文明“旋回”的节奏。
To understand the rhythm of climatic “cyclical return” is to understand the rhythm of civilizational “cyclical return.”
03 距今5400年前后
03 Around 5,400 Years Ago
三皇时代的思想成就与5400年前的海侵冲击，共同塑造了黄土高原在五帝时期的文明格局。
The intellectual achievements of the Three Sovereigns era and the transgression of 5,400 years ago together shaped the civilizational configuration of the Loess Plateau during the Five Emperors period.
距今8200至5400年前，地球处于大暖期的持续阶段。黄土高原气候温润，植被茂密，为文明的孕育提供了最优越的自然条件。正是在这一时期，中华文明的思想根基得以奠定。
From 8,200 to 5,400 years ago, the Earth was in the sustained phase of the great warm period. The Loess Plateau had a mild climate and dense vegetation, offering the most favorable natural conditions for the gestation of civilization. It was during this period that the intellectual foundations of Chinese civilization were laid.
燧人氏时期，中华文明开始缔结，确立了“天、地、人”三道思维框架。伏羲氏时代将八索演绎成八卦；神农氏制耒耜、种五谷、尝百草。据第三次全国文物普查数据，仰韶文化遗址有5000多处，仅中原地区就有3000多处。黄帝在位期间，文字、音乐、历数、宫室、舟车等发明相继出现。三皇时代的文化成就，为后世五帝时期的社会整合提供了思想和物质基础。从巫鬼崇拜到人文觉醒，从敬畏自然到主动改造，这一“变巫为儒”的思想转型，正是在三皇五帝的漫长时期中逐步完成的。
During the Suiren period, Chinese civilization began to take form, establishing the three-principle framework of Heaven, Earth, and Human. In the Fuxi era, the eight cords were elaborated into the Eight Trigrams; Shennong made ploughs, planted the five grains, and tasted the hundred herbs. According to the Third National Cultural Relics Census, there are over 5,000 Yangshao culture sites, more than 3,000 of them in the Central Plains alone. During the reign of the Yellow Emperor, inventions such as writing, music, calendrical calculation, palaces, boats, and carts appeared in succession. The cultural achievements of the Three Sovereigns era provided the intellectual and material foundation for the social integration of the later Five Emperors period. From shamanic worship to humanistic awakening, from revering nature to actively transforming it, this transformation of “turning shamanism into Confucianism” was gradually completed over the long span of the Three Sovereigns and Five Emperors.
距今约5400年前，发生了一次重要的海侵事件，海平面上升至比现在高出约20米。海水淹没了第三阶梯的大片沿海低地，原居长江下游巢湖流域的凌家滩文化受到严重冲击。凌家滩文化是中华文明“古国时代”第一阶段的杰出代表，遗址出土了精美的玉器、完整的宇宙观体系，玉版上刻有八角星纹，是“天圆地方”宇宙观最早的实物见证之一。凌家滩先民的玉器加工精度达到惊人的0.15毫米，其社会组织、等级制度与稻作文明均已达到相当高度。
Around 5,400 years ago, a major transgression raised sea level to about 20 meters above present. Seawater submerged large stretches of coastal lowland on the Third Step. The Lingjiatan culture, originally in the Chaohu basin of the lower Yangtze, was severely affected. Lingjiatan is an outstanding representative of the first phase of China’s “ancient state era.” The site yielded exquisite jades and a complete cosmological system; an eight-pointed star pattern carved on a jade plaque is one of the earliest material witnesses to the “round heaven, square earth” cosmology. Lingjiatan jade-working precision reached an astonishing 0.15 millimeters, and its social organization, hierarchy, and rice-farming civilization had all reached considerable heights.
海侵迫使凌家滩先民大规模迁徙，一支沿长江、淮河流域逆流而上，涌入黄土高原所在的第二阶梯，将玉器传统、八角星纹宇宙观带入黄土高原，与当地文化融合。凌家滩的文化要素正是通过这次迁徙在黄土高原沉淀下来，深刻影响了后世中华文明的空间哲学。
The transgression forced the Lingjiatan people into large-scale migration. One branch traveled upstream along the Yangtze and Huai river basins into the Second Step, where the Loess Plateau lies, carrying the jade tradition and the eight-pointed-star cosmology with them, and fused with local cultures. It was through this migration that Lingjiatan’s cultural elements settled into the Loess Plateau and profoundly shaped the spatial philosophy of later Chinese civilization.
距今约5000余年前，黄帝、炎帝、蚩尤三大部族在涿鹿汇聚。炎黄部落是黄土高原的农耕联盟，依托第二阶梯的河谷与台地发展了成熟的粟作农业；蚩尤则代表第三阶梯的东夷族群，长期生活在滨海低地。5400年前的海侵不断挤压第三阶梯的生存空间，蚩尤部落被迫西进。经过阪泉之战与涿鹿之战，三大部族最终走向融合，形成了中华民族最早的雏形，并创造了共同的图腾——龙。
Around 5,000 years ago, the three great tribes of the Yellow Emperor, the Yan Emperor, and Chiyou converged at Zhuolu. The Yan-Huang tribes were an agrarian alliance of the Loess Plateau, developing mature millet agriculture on the river valleys and tablelands of the Second Step. Chiyou represented the Dongyi peoples of the Third Step, long settled in coastal lowlands. The transgression of 5,400 years ago kept squeezing the living space of the Third Step, forcing Chiyou’s tribe westward. After the Battle of Banquan and the Battle of Zhuolu, the three tribes ultimately moved toward fusion—forming the earliest prototype of the Chinese nation and creating a common totem: the dragon.
距今5400至4200年前，进入五帝时期，气候历经暖盛到冷干到回暖三阶段。甘肃秦安大地湾遗址、河南巩义双槐树遗址、甘肃庆阳南佐遗址、山西南部陶寺古城，这些遗址的规模与密度表明，黄土高原在五帝时期已成为中华文明的核心区域。陶寺古城发现了迄今最早的朱书文字，将中国有文字可考的历史向前推进了一大步，也证明当时的社会已进入文明阶段。
From 5,400 to 4,200 years ago came the Five Emperors period, with the climate passing through three phases: warm prosperity, cold-dryness, and warming. The Dadiwan site in Qin’an, Gansu; the Shuanghuaishu site in Gongyi, Henan; the Nanzuo site in Qingyang, Gansu; the Taosi ancient city in southern Shanxi—their scale and density show that the Loess Plateau had already become the core region of Chinese civilization during the Five Emperors period. Taosi yielded the earliest known vermilion writing, pushing China’s documentable history forward by a great step and proving that society had entered the civilizational stage.
2026年入选全国十大考古新发现的南佐遗址，为此提供了最有力的物证。南佐遗址位于泾河上游董志塬上，距今约5100至4700年，总面积约600万平方米。核心区由9座大型夯土台及环壕构成，存在一条贯穿南北的中轴线，这是中国古代目前所见年代最早、最为清晰的都邑聚落中轴线。南佐遗址的“九台”布局与《旋回》的“九宫格”空间哲学形成跨越时空的呼应。九座夯土台呈倒“U”字形围合核心区，“九台”位于遗址中心，宫城位于九台中心，主殿位于宫城中心，层层向心，将空间秩序与权力秩序融为一体。宫殿区已呈现中轴对称格局，南北向中轴线清晰可辨，证明五千年前黄土高原已诞生了结构复杂、礼制初现的早期国家形态。
The Nanzuo site, selected in 2026 as one of China’s Top Ten Archaeological Discoveries, provides the strongest material evidence. Nanzuo lies on the Dongzhi Tableland in the upper Jing River, dating to about 5,100–4,700 years ago, with a total area of roughly 6 million square meters. Its core consists of nine large rammed-earth platforms and a ring moat, with a north-south central axis—the earliest and clearest central axis of a capital settlement yet seen in ancient China. The “nine platforms” layout at Nanzuo resonates across time with the “Nine-Palace” spatial philosophy of Xuanhui. The nine platforms form an inverted “U” enclosing the core; the “nine platforms” sit at the center of the site, the palace city at the center of the nine platforms, the main hall at the center of the palace city—layer upon layer toward the center, fusing spatial order with the order of power. The palace area already shows axial symmetry, with a clearly legible north-south central axis, proving that 5,000 years ago the Loess Plateau had already given birth to an early state form with complex structure and incipient ritual order.
04 距今4200年前后
04 Around 4,200 Years Ago
距今约4200年前，发生了一次更为严重的海侵事件，海平面上升至比现在高出约66米。这是已知最严重的海侵现象，海水淹没了第三阶梯更广阔的土地。原居长江下游太湖流域的良渚文化彻底崩溃，龙山文化、石家河文化也受到严重冲击。先民被迫向西、向北大规模转移，先进的生产技术、精致的玉器、系统的宇宙观沿长江、淮河流域逆流而上，涌入黄土高原。与此同时，两河流域的苏美尔文明、印度河流域的哈拉帕文明也同步消失于海侵线下，并向第二阶梯转移。古埃及古王国也在同一时间窗口内崩溃，残余势力向南退入努比亚。四大文明在同一个时间窗口内被同一种力量撼动，被迫向不同方向转移。
Around 4,200 years ago, an even more severe transgression raised sea level to about 66 meters above present. This is the most severe known transgression; seawater submerged still broader stretches of the Third Step. The Liangzhu culture, originally in the Taihu basin of the lower Yangtze, collapsed entirely; Longshan and Shijiahe cultures were also severely affected. The ancestors were forced into large-scale westward and northward migration. Advanced production techniques, exquisite jades, and systematic cosmology traveled upstream along the Yangtze and Huai river basins into the Loess Plateau. At the same time, the Sumerian civilization of Mesopotamia and the Harappan civilization of the Indus valley disappeared below the transgression line and moved to the Second Step. The Old Kingdom of Egypt also collapsed within the same window, its remnants retreating south into Nubia. Four great civilizations were shaken by the same force within the same window, forced to move in different directions.
良渚文化的玉琮、玉璧等礼器系统，承载着以“方圆”为核心的宇宙观，随着人群的迁徙进入黄土高原。玉琮从长江下游沿江逆流而上，经荆楚、汉水进入黄土高原，最终在陕北石峁遗址的皇城台墙体中以“藏玉于墙”的形式沉淀下来。陕北石峁遗址的出现，正是这一“格式化”过程的物质见证。“格式化”在此处的含义是：原有文明程序被清除或覆盖，新的文明程序在“清零”的基础上重新写入。良渚、龙山等第三阶梯文明的文化基因被压缩、打包、写入黄土高原的第二阶梯文明程序之中，以新的形态继续运行。2025年，中国科学院付巧妹团队与陕西省考古研究院在《自然》杂志发表了石峁遗址古DNA研究成果，基于169例古代人骨样本的大规模核基因组分析，确凿证实石峁文化人群主体源于陕北仰韶晚期人群，其文化和人群发展具有连续性。研究还重建了石峁古城内部横跨四代的家族谱系，清晰透视了其以父系亲缘为核心构建社会等级的运行模式。宏伟的皇城台、复杂的城门结构、大量的良渚风格玉器，表明在夏朝建立之前，黄土高原上已经出现了具有早期国家形态的复杂社会。
The jade cong, jade bi, and other ritual vessel systems of the Liangzhu culture carried a cosmology centered on “square and circle,” and entered the Loess Plateau with the migration of peoples. The jade cong traveled upstream from the lower Yangtze through Jing-Chu and the Han River into the Loess Plateau, ultimately settling in the form of “jade hidden in walls” in the Huangchengtai walls of the Shimao site in northern Shaanxi. The appearance of Shimao is precisely the material witness of this “formatting” process. “Formatting” here means that the original civilizational program was cleared or overwritten, and a new program was written on the cleared foundation. The cultural genes of Third Step civilizations such as Liangzhu and Longshan were compressed, packaged, and written into the Second Step civilizational program of the Loess Plateau, continuing to operate in new forms. In 2025, the team of Fu Qiaomei of the Chinese Academy of Sciences and the Shaanxi Provincial Institute of Archaeology published ancient DNA research on Shimao in Nature. Based on large-scale nuclear genome analysis of 169 ancient human bone samples, it conclusively confirmed that the main population of Shimao culture originated from the late Yangshao population of northern Shaanxi, with continuous cultural and population development. The research also reconstructed a family lineage spanning four generations within Shimao ancient city, clearly revealing a mode of social hierarchy built around patrilineal kinship. The grand Huangchengtai, complex gate structures, and numerous Liangzhu-style jades indicate that before the establishment of the Xia dynasty, a complex society with an early state form had already appeared on the Loess Plateau.
蚩尤战败后，其族群并未完全消失。在海侵的持续压力下，蚩尤残部一部分融入华夏，一部分向南迁徙进入长江中游与珠江流域，成为后世苗族、瑶族、畲族等民族的先民。4200年前的海侵加剧了第三阶梯人群的西进压力，各地迁徙浪潮叠加，加速了文明格局的重塑。黄土高原在这一过程中再次成为第三阶梯移民的“避风港”和“熔炉”，完成了又一次“吸纳”与“整合”。
After Chiyou’s defeat, his people did not disappear entirely. Under the sustained pressure of transgression, part of the remnants merged into the Huaxia, and part migrated south into the middle Yangtze and Pearl River basins, becoming ancestors of later peoples such as the Miao, Yao, and She. The transgression of 4,200 years ago intensified westward pressure on Third Step populations; overlapping waves of migration accelerated the reshaping of the civilizational order. In this process, the Loess Plateau once again became a “safe harbor” and a “furnace” for Third Step migrants, completing another round of absorption and integration.
距今4200至3000年前，进入三代时期。在黄土高原西缘，接续这一文化浪潮的是齐家文化，甘青地区已形成较为系统的青铜生产技术，并大规模引种了源自西亚的小麦和大麦。商末气候转冷，西周晚期汉江冰冻，犬戎入侵。正是在冷暖交替的旋回中，西周原点得以建立，文王作《周易》，太公作《山海经》，姬旦作《周礼》。源于“九宫格”认知的“井田制”与“井田城市”也在三代时期被确立，成为3000年来空间的营造逻辑与形式总图。春秋战国时期，诸子百家集中涌现，中国哲学完成了变“巫”为“儒”的历史性转变。
From 4,200 to 3,000 years ago came the Three Dynasties period. On the western edge of the Loess Plateau, the Qijia culture continued this cultural wave; the Gan-Qing region had already developed relatively systematic bronze production and extensively introduced wheat and barley originating in West Asia. At the end of the Shang the climate turned cold; in the late Western Zhou the Han River froze and the Quanrong invaded. It was precisely in this cyclical return of cold and warmth that the Western Zhou origin was established: King Wen composed the Zhouyi, the Grand Duke composed the Shan Hai Jing, and Ji Dan composed the Zhou Li. The “well-field system” and “well-field cities” derived from “Nine-Palace” cognition were also established during the Three Dynasties, becoming the logic of spatial creation and the master plan of form for 3,000 years. During the Spring and Autumn and Warring States periods, the Hundred Schools of Thought emerged in concentration, and Chinese philosophy completed the historic turn from shamanism to Confucianism.
秦汉隋唐，黄土高原所在的关中平原继续作为中华文明的政治与文化核心。秦人立足关中，完成了“大一统”的政治框架，郡县制、书同文、车同轨、统一度量衡，为历代王朝奠定了权威性的规范。汉承秦制，长安成为丝绸之路的起点，黄土高原的文化基因通过制度、文字、伦理向整个东亚大陆辐射。隋唐时期，长安更是成为当时全球最大的城市，人口超过100万，70多个外交使团，3万多个外国留学生，成为大环道上文明交流最耀眼的枢纽。宋元明清，虽政治重心东移北上，但黄土高原作为中华文明根脉的地位从未动摇，元大都、明清北京城的规划，依然遵循着西周“九经九纬”“左祖右社”的营国理念。
Through Qin-Han and Sui-Tang, the Guanzhong Plain where the Loess Plateau lies remained the political and cultural core of Chinese civilization. The Qin, based in Guanzhong, completed the “great unity” political framework—the system of commanderies and counties, the same writing, the same track gauge, unified weights and measures—laying down authoritative norms for successive dynasties. Han inherited the Qin system; Chang’an became the starting point of the Silk Road; the cultural genes of the Loess Plateau radiated through institutions, writing, and ethics across the East Asian continent. In the Sui-Tang period, Chang’an became the largest city in the world at the time, with a population of over one million, more than 70 diplomatic missions, and over 30,000 foreign students—the most dazzling hub of civilizational exchange on the Great Corridor. Through Song-Yuan-Ming-Qing, although the political center shifted east and north, the Loess Plateau’s status as the root of Chinese civilization never wavered. The planning of Yuan Dadu and Ming-Qing Beijing still followed the Western Zhou state-building ideal of “nine longitudinal and nine latitudinal avenues” and “ancestral temple on the left, altar of soil and grain on the right.”
05 收缩与扩张
05 Contraction and Expansion
黄土高原的文明史，从来不是单向度的线性发展，而是收缩与扩张的交替往复。冷期收缩自守，暖期向外扩张。每一次收缩与扩张，都是文明在“吸纳——淬炼——辐射”循环中的自我更新。
The civilizational history of the Loess Plateau has never been unidirectional. It alternates between contraction and expansion. In cold periods it contracts and holds; in warm periods it expands outward. Every contraction and expansion is a self-renewal of civilization within the cycle of “absorption—refinement—radiation.”
冷期收缩：石城防御与力量的凝聚
Cold-Period Contraction: Stone-City Defense and the Cohesion of Strength
距今4200年前后，全球进入干冷期。陕北高原的黄土梁峁上，涌现出数十处石城遗址。石峁遗址是这一防御体系的顶峰，拥有内外两道石墙，城墙上设马面、角楼，城门设瓮城，外城东门被誉为“华夏第一门”。石峁外城东门遗址出土了陶器、玉器、壁画等大量珍贵文物，城门结构复杂，由内外瓮城、门道、墩台等组成，体现了高超的防御工程技术。石城的修建并非为了日常居住，而是应对掠夺者的避难场所。石峁古DNA研究证实其主体人群为华夏人，他们建城防范的是来自北方的压力。当气候变冷，北方游牧力量南下压力增大，先民便退守高地，以石城为盾，构筑起防御链条。冷期的压力迫使先民凝聚力量，石城的修建需要大规模组织协调，这种“被迫的凝聚”反而强化了文明的内聚力和组织力。每一次冷期的收缩，都是一次“淬火”，在压力中锻造韧性，在危机中积蓄力量。
Around 4,200 years ago, the globe entered a dry-cold period. On the loess ridges of the Northern Shaanxi Plateau, dozens of stone-city sites emerged. Shimao is the peak of this defensive system, with inner and outer stone walls, bastions and corner towers on the walls, and a barbican at the gate; the eastern gate of the outer city is hailed as “China’s First Gate.” The eastern gate site of Shimao’s outer city yielded large quantities of precious artifacts—pottery, jades, murals—with a complex gate structure composed of inner and outer barbicans, gate passages, and platforms, embodying superb defensive engineering. The stone cities were not built for daily habitation but as refuges against raiders. Ancient DNA research on Shimao confirms that its main population was Huaxia; they built cities to guard against pressure from the north. When the climate turned cold and the southward pressure of northern nomadic forces increased, the ancestors retreated to high ground, using stone cities as shields to build a defensive chain. The pressure of cold periods forced the ancestors to consolidate strength; the construction of stone cities required large-scale organization and coordination; this “forced cohesion” in turn strengthened civilization’s internal cohesion and organizational capacity. Every cold-period contraction is a “quenching”—forging resilience under pressure, accumulating strength in crisis.
暖期扩张：文明辐射与新的融入
Warm-Period Expansion: Civilizational Radiation and New Integration
与冷期的收缩自守相对应，暖期则是黄土高原文明向外扩张的窗口期。距今5400至4200年前，黄土高原的文化影响力向四周辐射：向西，仰韶文化系统扩展至甘青地区；向北，红山文化的玉器沿燕山南北一线南下；向东南，龙山文化的黑陶和玉器沿黄河、淮河流域传播至整个华北平原；向南，甘青人群沿横断山脉河谷向云贵高原迁徙。与此同时，这些线路也成为外来文化要素涌入的管道，来自中亚的青铜技术、小麦种植沿羌中道传入，来自南方的稻作技术沿长江汉水一线北上。每一次暖期的扩张，都是一次“融炉”，在辐射中传播文明，在吸纳中完成新的提升。
In contrast to cold-period contraction and self-preservation, warm periods were windows of outward expansion for the Loess Plateau. From 5,400 to 4,200 years ago, its cultural influence radiated in all directions: westward, the Yangshao culture system expanded into the Gan-Qing region; northward, Hongshan jades moved south along the Yanshan line; southeastward, Longshan black pottery and jades spread along the Yellow and Huai river basins across the North China Plain; southward, Gan-Qing populations migrated along the Hengduan Mountain valleys toward the Yunnan-Guizhou Plateau. At the same time, these routes became conduits for incoming foreign elements: bronze technology and wheat cultivation from Central Asia entered along the Central Qiang Route; rice-farming technology from the south moved north along the Yangtze-Han River line. Every warm-period expansion is a “melting furnace”—spreading civilization through radiation, achieving new elevation through absorption.
收缩与扩张，看似相反，实则一体。冷期在防御中凝聚力量、淬炼韧性；暖期在辐射中传播文明、吸纳外来养分。这种“有张有守”的循环往复，正是“旋回自洽”在黄土高原上的生动实践。每一次循环，黄土高原都在“吸纳——淬炼——辐射”的完整周期中完成一次跃升，文明的高度在每一次“收缩——扩张”的交替中持续攀升。
Contraction and expansion appear opposite yet are in fact one. In cold periods, strength is consolidated and resilience tempered through defense; in warm periods, civilization is spread and external nutrients absorbed through radiation. This cyclical recurrence of “tension and preservation” is precisely the vivid practice of “cyclical return and self-consistency” on the Loess Plateau. In each cycle, the Loess Plateau completes a leap within the full sequence of “absorption—refinement—radiation,” and the height of civilization climbs with every alternation of “contraction—expansion.”
而八百里秦川，在每一次上山与下山的交替中，成为中华文明在第二阶梯上最坚实的脊梁。
And the Eight-Hundred-Li Qin Plain, in every alternation of ascent and descent, becomes the most solid spine of Chinese civilization on the Second Step.
06 四通八达
06 Reaching in All Directions
黄土高原从来不是封闭的。在“天地矩阵”中，它处于四条流域线与四条阶梯线的交汇节点，是四方文化流动的枢纽。而这片枢纽最核心的骨架，正是环青藏高原的三条文明传播大动脉与四大流域蓝脉网络的交汇。
The Loess Plateau has never been closed. In the “Heaven-Earth matrix,” it lies at the intersection of the four river basin lines and the four step lines—a pivot of cultural flow from all directions. At the core of this pivot lies the intersection of the three great civilizational transmission arteries around the Qinghai-Tibet Plateau with the blue-vein network of the four river basins.
环青藏高原大通道的三条动脉
The Three Arteries of the Great Corridor around the Qinghai-Tibet Plateau
围绕青藏高原存在三条贯穿万年的文明传播大动脉，以黄土高原为共同的东方枢纽。羌北道连接河西走廊与西域，距今约4000年前来自中亚的青铜铸造技术、小麦种植技术正是沿此线路传入黄土高原。羌中道东端出口直抵渭河流域，距今约8200至5400年前古羌人正是沿羌中道从高原东缘进入黄土高原。2025年考古调查确认，羌中道“西通西域并延伸至南亚、中亚、西亚，北连河西走廊以通南北，南达西藏、四川及云贵高原，东抵陕、甘、宁并延伸至中原”，“实为欧亚大陆早期文明互动不可或缺的十字枢纽”。羌南道向南沟通东亚与南亚。
Around the Qinghai-Tibet Plateau run three great civilizational arteries spanning ten thousand years, with the Loess Plateau as their common eastern pivot. The Northern Qiang Route connects the Hexi Corridor and the Western Regions; bronze-casting and wheat cultivation from Central Asia entered the Loess Plateau along this route around 4,000 years ago. The eastern exit of the Central Qiang Route reaches directly into the Wei River basin; from about 8,200 to 5,400 years ago, the ancient Qiang entered the Loess Plateau from the eastern edge of the plateau along this route. A 2025 archaeological survey confirmed that the Central Qiang Route “extends west to the Western Regions and further to South Asia, Central Asia, and West Asia; north to the Hexi Corridor linking north and south; south to Tibet, Sichuan, and the Yunnan-Guizhou Plateau; and east to Shaanxi, Gansu, and Ningxia, extending into the Central Plains”—“truly an indispensable cross-hub of early Eurasian civilizational interaction.” The Southern Qiang Route connects East Asia and South Asia to the south.
三条动脉与各条次一级线路形成完整闭合：羌中道与黄河沿线、西辽河-西拉木伦河一线在河套地区交汇；羌北道经蒙古高原与燕山南北一线相接；羌南道与藏彝走廊、长江汉水一线相连。主次线路相互交织，构成了一个以黄土高原为中心的完整空间网络。
The three arteries and their secondary routes form a complete closure: the Central Qiang Route intersects with the Yellow River line and the Xiliao-Xilamulun line in the Hetao region; the Northern Qiang Route connects with the north-south Yanshan line via the Mongolian Plateau; the Southern Qiang Route connects with the Zang-Yi Corridor and the Yangtze-Han River line. Primary and secondary routes interweave, forming a complete spatial network centered on the Loess Plateau.
四大流域的蓝脉网络
The Blue-Vein Network of the Four River Basins
书中将中国大陆的流域概括为四条东西向的“蓝脉”：西辽河-塔里木河线、黄河线、长江线、珠江线。黄土高原恰好坐落于黄河线的中游。
The book summarizes China’s river basins into four east-west “blue veins”: the Xiliao-Tarim line, the Yellow River line, the Yangtze line, and the Pearl River line. The Loess Plateau sits precisely in the middle reaches of the Yellow River line.
与西辽河-塔里木河流域：红山文化的玉器沿燕山南北一线南下，与黄土高原的龙山文化相遇，其文化要素通过黄土高原汇入了中华文明的主干。与黄河流域：黄河及其支流渭河、泾河、洛河、汾河，构成了黄土高原文明发生与传播的主动脉，八百里秦川正是黄河中游最精华的段落，西周正是在此确立了“井田制”与“井田城市”的空间形制。与长江流域：石家河文化、屈家岭文化通过长江汉水一线输入黄土高原，距今4200年前的海侵之后，良渚文明的一支北上，最终在陕北石峁沉淀下来。与珠江流域：通过西南线路与沿海线路相连。
With the Xiliao-Tarim basin: Hongshan jades moved south along the Yanshan line and met the Longshan culture of the Loess Plateau; their cultural elements merged into the trunk of Chinese civilization through the Loess Plateau. With the Yellow River basin: the Yellow River and its tributaries—the Wei, Jing, Luo, and Fen—constitute the aorta of the Loess Plateau’s civilizational genesis and transmission; the Eight-Hundred-Li Qin Plain is the most essential stretch of the middle Yellow River, and it was here that the Western Zhou established the spatial form of the “well-field system” and “well-field cities.” With the Yangtze basin: Shijiahe and Qujialing cultures entered the Loess Plateau via the Yangtze-Han River line; after the transgression of 4,200 years ago, one branch of Liangzhu civilization moved north and ultimately settled at Shimao in northern Shaanxi. With the Pearl River basin: connected via the southwestern and coastal routes.
龙州鲤的分布变迁，为气候旋回提供了独特的生物学证据。这种今天仅分布于广西西江上游的鱼类，其咽齿骨却在距今约8200年前的河南贾湖遗址中被大量发现，当时淮河流域的气候类似于今日广西西江流域。随着气候转冷，龙州鲤的分布从淮河南缩至珠江流域，成为气候“旋回”的活体证据，也印证了黄土高原与珠江流域之间跨越数千年的生态与文化联系。
The distributional shift of the Longzhou carp provides unique biological evidence for climatic cyclical return. This fish, found today only in the upper reaches of the Xijiang River in Guangxi, left quantities of pharyngeal teeth at the Jiahu site in Henan around 8,200 years ago, when the climate of the Huai River basin resembled today’s Xijiang basin. As the climate cooled, its range contracted southward from the Huai River to the Pearl River basin—living evidence of climatic “cyclical return,” and corroboration of an ecological and cultural link across thousands of years between the Loess Plateau and the Pearl River basin.
四大空间节点
Four Spatial Nodes
环绕八百里秦川，四大空间节点如同通向四方的门户：晋南陶寺古城是向东南延伸的支点，是中原地区早期更为成熟的国家形态代表；豫北二里头遗址呈现“九宫格”式布局，标志着文明从“方国”走向“广域王权国家”；陕南汉水谷地是南北文化流动的关键节点；甘南洮河、大夏河流域是羌中道进入黄土高原的门户，多元文化在此融合。关中盆地本身四面关塞，东有函谷关、西有大散关、南有武关、北有萧关，四关固守使八百里秦川成为“四塞之地”，既可在暖期向四方辐射文化，又可在冷期闭关自守、保存实力。
Surrounding the Eight-Hundred-Li Qin Plain, four spatial nodes serve as gateways to the four directions: Taosi in southern Shanxi is the fulcrum extending southeast, representing a more mature early state form in the Central Plains; Erlitou in northern Henan displays a “Nine-Palace” layout, marking civilization’s movement from “square states” to a “broad-territory kingly state”; the Han River valley in southern Shaanxi is a key node of north-south cultural flow; the Tao and Daxia river basins in southern Gansu are the gateway through which the Central Qiang Route enters the Loess Plateau, where diverse cultures fuse. The Guanzhong Basin itself is enclosed by passes on four sides—Hangu to the east, Dasan to the west, Wu to the south, Xiao to the north. With the four passes secured, the Eight-Hundred-Li Qin Plain becomes a “land of four enclosures,” able both to radiate culture in all directions in warm periods and to close itself off and preserve strength in cold periods.
从甘肃永靖的炳灵寺，到山西永济的鹳雀楼，一条黄河串起了黄土高原的东西两端。炳灵寺的佛像，见证了佛教沿羌中道东传的足迹；鹳雀楼的诗句，记录了中华文明对天地日月的凝视。从永靖到永济，不只是地理的穿越，更是文明的行走。永靖则永济，黄河入海流。
From Bingling Temple in Yongjing, Gansu, to Guanque Tower in Yongji, Shanxi, a single Yellow River strings together the eastern and western ends of the Loess Plateau. The Buddha statues of Bingling Temple witness Buddhism’s eastward passage along the Central Qiang Route; the verses of Guanque Tower record Chinese civilization’s gaze upon Heaven, Earth, sun, and moon. From Yongjing to Yongji is not merely a geographic traverse but a walking of civilization. Yongjing then Yongji—the Yellow River flows into the sea.
来自海洋的推动力同样不可忽视。海侵海退的反复发生，深刻塑造了黄土高原与海洋文化的关系。距今5400年前的海侵，导致凌家滩文化向第二阶梯转移。距今4200年前的海侵，是海岸线离黄土高原最近的时候，良渚文化、苏美尔文明、哈拉帕文明同时消失于海侵线下，并向第二阶梯大规模转移。黄土高原在这一过程中成为第三阶梯移民的“避风港”和“熔炉”。书中将四条阶梯线概括为穆大陆线、凌家滩线、良渚-苏美尔线、亚细亚线，黄土高原所在的第二阶梯正是在每一次海侵中吸纳第三阶梯的文明成果，又在每一次海退中将淬炼后的文明成果向第三阶梯辐射。
The driving force from the ocean is equally not to be ignored. The repeated occurrence of transgression and regression profoundly shaped the Loess Plateau’s relationship with maritime culture. The transgression of 5,400 years ago caused the Lingjiatan culture to move to the Second Step. The transgression of 4,200 years ago was when the coastline was closest to the Loess Plateau: Liangzhu culture, Sumerian civilization, and Harappan civilization disappeared below the transgression line at the same time and migrated on a large scale to the Second Step. In this process, the Loess Plateau became a “safe harbor” and a “furnace” for Third Step migrants. The book summarizes the four step lines as the Mu Continent Line, the Lingjiatan Line, the Liangzhu-Sumer Line, and the Asia Line. The Second Step where the Loess Plateau lies absorbed the civilizational achievements of the Third Step in each transgression, and radiated the refined achievements back to the Third Step in each regression.
而太行山是横亘在高原与海洋之间的天然屏障，八陉则是这道屏障上被河流切割、被时间磨出的连接第二、三阶梯的天然“石门”。它们不仅是人员迁徙和物资流通的必经之路，更是高原文明向外延伸的生命线。
And the Taihang Mountains are a natural barrier between the plateau and the ocean; the Eight Gorges are natural “stone gates” on that barrier, cut by rivers and worn by time, connecting the Second and Third Steps. They are not only indispensable routes for migration and material flow but lifelines for the plateau civilization’s outward extension.
正是通过这一“四通八达”的格局，大环道三条动脉及其次一级闭合网络、四大流域的蓝脉网络、四大空间节点的门户支撑，黄土高原完成了四方文化的“汇聚——淬炼——辐射”的完整循环。它不是被动地接收，而是主动地转化；不是简单地叠加，而是有机地重构。
It is precisely through this “reaching in all directions” configuration—the three arteries of the Great Corridor and their secondary closed networks, the blue-vein network of the four river basins, and the gateway support of the four spatial nodes—that the Loess Plateau completed the full cycle of “convergence—refinement—radiation” of cultures from all directions. It is not passive reception but active transformation; not simple superposition but organic reconstruction.
结语
Conclusion
黄土高原的历程，是“旋回自洽”理论的绝佳注脚。它既是气候变迁的记录者，黄土层本身封存着数百万年地球冷暖交替的信息，安芷生院士的“东亚季风变迁三旋回”理论正是从这片土地中读出的气候史诗；也是文明序列的存续者，三皇五帝在此活动，三代九朝在此兴替，四方文化在此汇聚、淬炼，最终升华为中华文明的完整形态。
The course of the Loess Plateau is the perfect footnote to “cyclical return and self-consistency.” It is both a recorder of climatic change—the loess layers seal millions of years of Earth’s cold-warm alternation, and Academician An Zhisheng’s theory of “Three Cyclical Returns of East Asian Monsoon Change” is the climatic epic read from this land—and a preserver of the civilizational sequence: the Three Sovereigns and Five Emperors were active here, the Three Dynasties and Nine Reigns rose and fell here, cultures from all directions converged and were refined here, ultimately sublimating into the complete form of Chinese civilization.
从距今243万年的西侯度火种到南佐遗址的中轴线城市，从青铜技术的早期探索到石峁遗址的古DNA家族谱系，再到二里头、殷墟，直至汉唐长安，黄土高原保存了一条在地球上绝无仅有的、完整而连续的人类文明演进序列。南佐遗址的“九台”与“中轴线”证明五千年前的黄土高原已孕育了礼制国家的雏形；石峁遗址的父系家族与社会等级，是中华文明“多元一体”格局在遗传学上的实证。每一次海侵都是一次“格式化”，每一次暖期都是一次“重启”，每一次冷期都是一次“淬火”。黄土高原的文明程序正是在这种“格式化——重启——淬火”的循环中不断升级，从仰韶的彩陶到龙山的黑陶，从石峁的石城到二里头的宫城，从西周的礼制到秦朝的帝制，每一轮循环都使文明上升一个台阶。
From the Xihoudu fire of 2.43 million years ago to the central-axis city of Nanzuo, from early bronze technology to the ancient DNA family lineage of Shimao, and on to Erlitou, Yinxu, and the Chang’an of Han-Tang, the Loess Plateau preserves an unparalleled, complete, and continuous sequence of human civilizational evolution on Earth. The “nine platforms” and “central axis” of Nanzuo prove that 5,000 years ago the Loess Plateau had already gestated the prototype of a ritual state; the patrilineal family and social hierarchy of Shimao are genetic evidence of Chinese civilization’s “unity in diversity.” Every transgression is a “formatting,” every warm period a “restart,” every cold period a “quenching.” The civilizational program of the Loess Plateau upgrades itself through this cycle of “formatting—restart—quenching”: from Yangshao painted pottery to Longshan black pottery, from Shimao stone city to Erlitou palace city, from Western Zhou ritual order to Qin imperial system—each cycle raises civilization one step higher.
八百里秦川是它的心脏，大环道三条动脉是它连接世界的血脉，四大流域是它横向伸展的臂膀，四大节点是它通向四方的门户。冷则收缩自守，以石城为盾；暖则向外扩张，以文明为矛。它四通八达，连接四方，在每一次汇聚中淬炼，在每一次辐射中传播，周秦汉唐，莫不如此。
The Eight-Hundred-Li Qin Plain is its heart; the three arteries of the Great Corridor are its blood vessels connecting to the world; the four river basins are its laterally extending arms; the four nodes are its gateways to the four directions. Cold, it contracts for self-preservation, using stone cities as shields; warm, it expands outward, using civilization as its spear. It reaches in all directions, connecting the four quarters, refining in each convergence, spreading in each radiation—Zhou, Qin, Han, Tang, all were thus.
安芷生院士用半个世纪的黄土研究告诉我们：气候在变，而且有其规律性。理解这种规律，顺应这种规律，在“旋回”中完成“自洽”，这不仅是黄土高原过去五千年的生存智慧，也是它面向未来的根本路径。
Academician An Zhisheng, through half a century of loess research, tells us: the climate is changing, and it has its regularity. To understand that regularity, to comply with it, and to complete “self-consistency” within “cyclical return”—this is not only the survival wisdom of the Loess Plateau over the past five thousand years but also its fundamental path toward the future.
黄土高原以它的地层记录了气候的“旋回”，又以它的文明承载了历史的“自洽”。这方土地本身就是一部活着的《旋回》，它用黄土写就的史书尚未合上，未来的篇章正等待着新一轮暖期中的中国人继续书写。
The Loess Plateau records the “cyclical return” of climate in its strata and bears the “self-consistency” of history in its civilization. This land is itself a living Xuanhui; the history book written in loess has not yet closed, and its future chapters await the Chinese people of a new warm period to continue writing.
