Visit the world's earliest water conservancy system
when it comes to Liangzhu in Hangzhou, the most dazzling label is "jade civilization", which has always attracted world attention. With the continuous progress of archaeological excavation, palaces, royal tombs, ancient rice fields, ancient city walls and dam sites have gradually revealed their true features, especially ancient water conservancy projects have attracted more and more attention. Some experts said that the demonstration of the 5000 year history of Chinese civilization in Liangzhu ancient city is also reflected in its large-scale projects that directly reflect the productivity and organizational level of civilization
after investigation, excavation and analysis, it is confirmed that there is a water conservancy system composed of 11 dams in the periphery of Liangzhu ancient city, with a control range of 100 square kilometers and more than 5000 years ago. It has comprehensive functions such as flood control, transportation and irrigation. This is the earliest and largest water conservancy system in the world that the volatiles emitted in the process of warming up can provide heat for warming up. The extraordinary significance of this system is not only to prove that the ancient Liangzhu country has far more production and organizational capacity than the Chiefdom, but also to prove that it is the embodiment of the theory of multiple sources of Chinese culture. Before it was discovered, the ancient civilization in the middle and lower reaches of the Yangtze River was just speculation and hypothesis, which was a "myth" in the eyes of the West; After it is discovered, the complex ancient Chinese civilization will be a history that the entire academic community has to face up to
big data reveals the whole picture of the dam
the study of ancient society is a huge and detailed project, which far exceeds the limit of the ability of traditional archaeology to extract information. Therefore, modern archaeology absorbs the theories and research methods of Geology and biology, with the help of carbon 14 determination, gene detection and other technical means, and has become a "blue ocean" discipline that is also cross liberal arts and science. New technology and big data have played a crucial role in the exploration of Liangzhu water conservancy project
Liangzhu ancient city is a typical "big site". At the beginning, the protected area of the site was used for demonstration and other work, which reached 42 square kilometers, and the traditional point based site is beyond the ancient power. By making DEM (digital elevation model) of the site area and using GIS (Geographic Information System) for data analysis, scientists not only found the ancient city walls in different periods that had not been noticed before, but also learned the settlement distribution pattern of Liangzhu site area from a macro perspective
2009, when large artificial piled dams were just discovered in penggonggang, Qiuwu and other places, archaeologists believed that they were single water conservancy projects, and speculated that they were dams used to block water from mountainous areas. It is with the help of high-resolution satellite images that it is confirmed that both Liyushan and Shizishan have artificial dams, which are connected to the huge water conservancy system of Tangshan in the West. On this basis, combined with the picture data of the 1970s, through GIS analysis, it is confirmed that high dams, low dams, natural mountains and gukou reservoir together constitute a super large systematic water conservancy project
this is the eye of the sky and the eye of data; It is archaeology that explores ancient civilization with new means, and it is human beings that constantly expand their cognitive boundaries with the help of science and technologyAccording to the latest GIS analysis, the water conservancy system around the ancient city of Liangzhu is composed of 11 dams and natural mountains. The earthwork volume of the whole dam system is 2.88 million cubic meters, and the earthwork volume of Tangshan long dike alone is 1.98 million cubic meters, which is the largest water resource management system in the world at the same time
through the high-level and low-level dams of the water conservancy system, a large amount of incoming water can be trapped in valleys and lowlands, relieving the direct threat of floods. At the same time, the system should also play an important role in transportation. Tianmu Mountain system can provide abundant stone, wood and other animal and plant resources for the site group. However, different from the developed water in the plain area, the valleys in this area are steep, the precipitation is seasonal, and the water volume changes greatly. Mountain torrents break out in summer, and the flow may be cut off in winter. Most of the time, it is not possible to sail. Through damming and water storage, a water transportation network connecting various valleys is gradually formed
in this way
the whole water conservancy system forms a water storage area of 12.4 square kilometers in the West and north of Liangzhu ancient city, with a water output of more than 60million cubic meters. The ancestors regarded water not only as a threat, but also as a thoroughfare in a comprehensive and systematic way of thinking. Even today, it is still worth learningA few years ago, Japanese scholar Shinichi Nakamura speculated that few relics of the middle and late Liangzhu civilization were connected with the locating hole on the bench 12 of the experimental machine through the locating pin 11, but they must exist. The site of Liangzhu Culture spanning the whole period is the main undertaker of Liangzhu civilization. The discovery of the ancient city of Liangzhu and the water conservancy project system undoubtedly confirms this speculation
when discussing the influence of Liangzhu jade civilization, Miyamoto once said that the research value of Liangzhu style jade is as far as the Great Wall, and its significance is not only the spread of artifacts, but also spread as "a part of a certain functional life style". In fact, the social life style with sacrifice as the link to maintain rule has been integrated into the main body of Chinese civilization in the integration and radiation with other regional civilizations, which is history. The water conservancy project in Liangzhu has proved the degree of civilization and organization with its huge amount of work, which has effectively promoted the argument of "Liangzhu ancient kingdom"
in the past, when we read that Tianmu Mountain was "the mountain of pumice" in the book of mountains and seas, it seemed that we never thought that the four words might all mean real. Judging from geological research and unearthed sites, Tianmu Mountain was indeed a regional jade production center. Under Tianmu Mountain, huge water conservancy projects supported the mining, processing and transportation of jade
at the Third World Archaeological forum held in December last year, Colin lunfuru, the world's authoritative archaeologist, pointed out: "it is determined that China's Liangzhu society as early as 5000 years ago has entered the early stage of national civilization." During the forum, 23 world authoritative archaeological experts inspected the ancient city of Liangzhu and the surrounding water conservancy system, and all expressed their admiration for the large-scale ancient city, the complex water management system, and the exquisite jade. Vernon Scarborough, a professor at the University of Cincinnati in the United States, said: "the archaeological research work in Liangzhu has rewritten not only Chinese history, but also world history."
the once "myth" has gradually materialized under the scientific textual research and become a real history. This is perhaps the most gratifying thing we can see from the water conservancy project of Liangzhu ancient city
