摘要
河姆渡地区在温暖期种子植物区系的地理分布,热带成分占31.7%,其中热带亚州成分具有相对优势,地带性植被组成以中亚热带和南亚热带地区成分为主.在距今7000~6000年前,河姆渡一带处于中亚热带南部,相当于气候带较个北移4~5个纬距.
This article analyses the animal and plant remains in more detail,obtained the third and fourth cultural deposit layers (about 7000 to 6000a B. P. )at Hemudu site in Zhejiang Province. Firstly, using Andersen's method.a correction is made for the percentage of various plant's spore and pollen in these layers. Secondly, on the basis of these results, the dominant species and the construction community species of zonal forest vegetation are identified, and the paleovegetation of Holocene Hypsithermal is reconstructed in Guangdong Hemudu region. Finally, contrasting the above-mentioned paleovegetation with the vegetation of Wuyanling Natural Reserve in southern Zhejiang and Dinghushan Natural Reserve in GuangDong today,the paleoclimate is also reconstructed in the said region during that time.
