摘要： 冰川阻塞湖的突然排水是叶尔羌河突发性洪水发生的根本原因.借助于对冰川阻塞湖库容的测量及分析,计算出可能的最大库容量,进而给出叶尔羌河今后可能的最大洪水流量为6888.40m3/s。

Abstract: The main reason why the flood water take place on Yerqiang River is that the river valley was blocked by glaciers. In the present paper, the reserve volume of glacier block lake in history is calculated with accuracy analysis on the base of the detail data, and the maximum reserve volume in the future is predicted. A group of models for reserve volume and flood amount on the down stream so as to calculate reserve volume and flood amount and to determine that which one of river valleys is blocked. Finally, the maximum flood water, which possibly appears in the future, is calculated 688.40 m3/s .
