Since the Quaternary,very thick lacustrine sediments have been deposited in Dalangtan of Qaidam Basin.Based on a study of high-resolution sporopollen analysis on the Dalangtan ZK06 drilling,and paleomagnetic dating data,and composite indicator of longitudinal change of sporopollen assemblages and aquatic plants and Arboreal plant / no Arboreal plant ratio(AP / NAP) and Broadleaved trees / Coniferous trees(B / C) and Artemisia / Chenopodiaceae ratio(A / C),This paper established 10 sporopollen zones and 10 vegetation evolution stages,and discussed climate cycles since the early Pleistocene in this area,and regionally compared with the Uplift effect of Tibetan Plateau and global change.
