Due to spatial distribution of the Yangshao cultural sites, they had a river-oriented trend in comparison with those in the Longshan Period. Apart from terrain factors, distribution of the sites in both periods is subject to paleo-environmental changes. The Yangshao Culture originated in Holocene Optimum Period, and the Longshan Culture started in climatic fluctuations prior to Neolithic ending. But the latter owned more sites and wider scopes than the former did. Both the Cultures devel- oped fast in rich rainfall and warm periods, and withered for abrupt cooling events in 5.4 ka BP and 4.0 ka BP respectively. Therefore, the sustainability of Henan＇s Neolithic Cultures is not good as expected. Whilst, the ancient farming acted an irreplaceable part in distribution of human sites, and the need for farming space prompted human sites to expand from the western hilly areas towards the eastern plain of Henan. Moreover, the neighboring cultures poured into Henan and complicated the cultural patterns. Besides, characteristics of the sites in the Erlitou Period suggest that some social factors disturbed the spatial pattern at the end of Neolithic age in Henan.展开更多

The age of archaeological strata was determined by AMS^14C dating. According to the results, combined with the information of the ancient human activities and the cultural heritage data obtained from the Longshan cultural archaeological strata, it can be concluded that （1） Before 4500 aBP, the climate was humid and water level was high in the Huaihe River and its tributaries, the drainage basin and its surrounding areas were even flooded, so the site area was submerged and there were no human activities around the site. （2） About 4500 aBP, the climate began to become drier and water level of the Huaihe River and its tributaries began to decline, thus floodplain gradually appeared, Yuhuicun Site and Longshan Culture began to appear. （3） Around 4100 aBP, the climate was humid and rainfall was abundant, which resulted in frequent flood disasters in the whole Huaihe River Basin. （4） After 4100 aBP, the climate gradually transited to be cold and dry, agricultural production was constrained to reduce the food source, Yuhuicun Site was almost abandoned. （5） The environmental information in sedimentary strata and historical records based on ancient books agree with each other. In addition, Yuhuicun Site was related to Dayu Zhishui （Yu the Great in taming the floods） in ancient books.展开更多
