Ancient dyke ruins found in C. China
An important achievement was made during recent excavations on the Longshan'gang Ancient Site, Xichuan County, Henan Province. Archeologists discovered a dyke ruins which was constructed in the later period of the Yangshao Age (Zhujiatai Culture).
It is a very rare one in cultural ruins of the same period in the middle reaches of the Han River
Also called the Huanglianshu Ancient Site, the Longshan'gang Ancient Site is a cultural relic protection project in the inundated area of the Danjiangkou Reservoir in the middle section of the South-to-North Water Diversion Project.
Since May 2008, the Institute of Cultural Relics in the Henan Province has been carrying out archaeological surveys and excavations on the site. Up to now, they have excavated 10,900 square meters in total.
After doing archaeological surveys and excavations for four successive years, archaeologists have fundamentally made clear the ranges and layout of the cultural relic piles of various periods of the Neolithic Age and made many important achievements.
This ancient site has abundant ruins, including ruins of the Qing Dynasty, Ming Dynasty, Song Dynasty, Yuan Dynasty, Han Dynasty, Western Zhou Dynasty, Wangwan Third Stage Culture, Shijiahe Culture, Qujialing Culture and later period of the Yangshao Age (Zhujiatai Culture). Their distribution range is wide. Types of the ruins include the dyke, large-scale multi-room house, ash pit and worshipping area, of which, the dyke ruins discovered this time is most significant.
The person in charge of excavating the ancient site said that the dyke ruins is located in the northeastern edge of the Neolithic Age ruins zone and has a south-to-north structure. Newly discovered ruins of the Neolithic Age are all located within the dyke (to the southwest of the dyke).
Outside the dyke is an ancient river channel (low land). The southeast end of the dyke is at the turning point of the river channel and the northwestern end of the dyke is at the northwestern part of the ancient site. The dyke was made of tamped mud and is very solid. The archaeological team also found that the internal slope of the dyke is on the remains of a collapsed house, which is preserved quite well.
From the ware excavated from the house, it could be judged that the dyke belonged to the later period of the Yangshao Culture (Zhujiatai Culture). The situation that many ruins of the later period of the Yangshao Culture accumulate on the internal slope of the dyke has also confirmed the construction time of the dyke.
Experts believe that, from the location and the surrounding tribe environment of the dyke, it could be judged that the function of the dyke was to control the flood. Since its construction structure is similar to those of many city and city wall ruins of the Neolithic Age discovered in the middle reaches of the Yangtze River, the dyke ruins not only has certain significance for studying the functions of the prehistoric city walls in the middle reaches of the Yangtze River but also has high academic values for researching the tribe formation transition and the law of the transition of this place in various periods of the Neolithic Age and for learning about the cultural appearance and nature of the connection region between the southern and north cultures.
