摘要： 根据湖盆地貌、湖泊沉积物分析,本文指出:中昆仑山区的封闭湖泊17000年以来湖面在总体下降过程中,出现了3期相对高湖面,近期湖泊仍在收缩咸化,未来仍将继续达一趋势。

关键词: 封闭湖泊湖面波动, 中昆仑山区

Abstract: Fluctuations of closed lake level results from the relative changes of lake water and volume of lake basin. For the closed-lake was constructed by drainage input lake and evaporation of lakesurface at the thousand years scale. So it was very sensitive that the fluctuations of closed-lake level respond to the changes of climate.It has provided trustworthy and easy comparison evidence to analyse the geomorphology of lake basins, lacustrine deposits, geochemical information and orgnisms ecological character reserved in the lacustrine deposits. Since 17000 a.B.P. the closed-lake level was shrinking, but appeared three stages of high lake level in the Middle kunlun Mountains. Recently, the closed-lake lever is shrinking. In future, the closed-lake level will shrink continually.

Key words: Fluctuations of closed-lake level, Middle Kunlun Mountains
