| Abstract: | Based on the data from a comprehensive survey to the Kekexili region in the central part of the Qinghai-Xizang(Tibet) Plateau, the authors discussed the lacustrine sedimentary sequences-ages event and compared with the remains of recent glacial activities, and set up a comprehensive column section and its time sequence regarding to environmental changes. Seven cycles of the environmental evolution time sequences from 32000 a.B.P. were classified and some new information for the understanding of the environment changes of the Qinghai-Xizang (Tibet) Plateau is provided. |
