PREHISTORIC CULTURE, CLIMATE AND AGRICULTURE AT YUCHISI, ANHUI PROVINCE, CHINA

摘要

A palaeoculture sediment profile from the Yuchisi site, Mengcheng County of Anhui Province, China, was sampled to study the concentrations of elements, total carbon content, grain size and pollen percentages, to reveal information on food supply based on statistical analysis of elements between 5050?cal.?yr bp and 4000?cal.?yr bp. The variations in the reconstructed food supply and pollen percentages are in good agreement with the results of other archaeological methods. The results from pollen and element analyses indicate that the Longshan Culture at the Yuchisi site was not developed from the local Dawenkou Culture, and the cultural transition corresponds with an extremely dry event, which may have caused the change.
