摘要

根据祁连山区地形、地质、水文、气象、植被和山洪灾害的调查资料

采用灾害实例调查法、频率分析法和产流分析法对比确定了临界雨量

根据洪水发生的频率和洪峰流量

划分典型流域的风险区域

可供祁连山区小流域山洪灾害防治应用和同类流域研究参考。

Abstract

In this paper

according to the investigation data on geography

geology

hydrology

weather

vegetation

and flood disaster in Qilian Mountain area

critical rainfall amounts were determined using Case Investigation Method of Disaster

Frequency Analysis Method

and Rainfall Formation Analysis Method.In addition

Risk areas in typical river basin were plotted based on frequency of flood and flood peak volume

which could be used for flood disaster prevention and control in small river basin in Qilian mountain area

as well as for a research reference in similar river basins.
