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。
In this paper, according to the investigation data on geography, geology, hydrology, weather, vegeta- tion, 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.
