摘要 通过对卡拉库勒湖地理、地质现状的野外调查,结合其周边现代冰川和古冰川遗迹的遥感解译分析,提出了该湖泊是由不同期次、不
同条冰川共同作用形成的结论。卡拉库勒湖原湖泊面积至少为20.05 km2,现在已经被分割成大小不等的3个湖泊,其中主体仍是卡拉库勒湖
,面积为4.73 km2,比最初形成时至少缩小了13.24 km2。根据该湖泊的演化特征,提出了湖泊生态环境保护的建设性意见,为帕米尔高原上
这颗璀璨旅游明珠的可持续发展提供了依据。

Abstract : Based on field investigation of the Karakul Lake and interpretation of existing glacier and former glacier
vestiges according to remote sensing images,the author has put forward the overall and reasonable genesis of the Karakul
Lake. According to the evolutionary characteristics of the lake,this paper makes some suggestions concerning the protection
of the eco-environment of the lake, and offers the evidence for sustainable development of this famous lake in the Pamirs.
