【Abstract】 Based on the analysis of the pollen samples from the Xiachuan site,the present paper makes a preliminary reconstruction of the palaeoclimatic and palaeoecological environments at the site. The climate-zone features of the Xiachuan pollen suggest that the site underwent six climatic changes from 36,000 to 12,000 BP.In this temporal scope,the early phase of the main Xiachuan cultural re- mains,lasting from 23,000 to 13,000 BP,corresponded just to the flourishing stage of the last glacia- tion,when the growth of trees at Xiachuan must have been concerned with the existence of mountain basins in this area;from 13,000 to 12,000 aBP,i.e.in the period of the late Xiachuan cultural remains corresponding to the Fen zhuang interstadial,there was the rise of the summer monsoon and a little going up of the temperature.更多还原
