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。
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 geo-morphology of lake basins, lacustrine deposits, geochemical information and or-gnisms 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.
