Abstract:

Based on the analyses of sporo-pollen,grain size and accelerator mass spectrometric (AMS)14C dating data from Taohuajian profile in Ruicheng County,Shanxi Province,this paper discusses the ancient cultural date and the paleoenvironmental change since Late Mid-Holocene. The study provides reliable quantitative data for the reconstruction of paleoenvironment in this area. The result shows that the climate is accord with its neighbouring areas,  and the ancient cultural date belongs to the period of Miaodigou culture. Three sporo-pollen assemblage zones are established through the stratigraphical changes of the sporo-pollen: the 5,250-5,000 aBP interval is a mild-wet climate with the landscape of  sparse prairie vegetation; the 5,000-4,800 aBP interval is a cool-dry climate with wilderness prairie vegetation; after 4,800 aBP there is a cool-wet climate with sparse prairie vegetation. 

Key words: Taohuajian profile, AMS 14C dating, sporopollen analysis, paleoenvironmental change
