摘要
可可西里地区位于青藏高原的腹地，以可可西里地区综合科学考察资料为依据，通过湖泊沉积物层序－年龄事件与近代冰川活动遗迹的对比研究，建立了环境变化的物性柱综合剖面及其时序性，将３２０００ａＢ．Ｐ．以来可可西里地区湖泊环境演化序列划分为７个旋，为深入认识青藏高原环境变迁提供新的信息。
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.
