摘　　要：随着社会的发展,洪水发生的频率越来越高,特别是在一些山洪频发地区,河道涨水快汇水急,必须得在洪水来临前做出精确化的洪水预警。还有如何确定洪水规模,为水利工程建设做好规划也一直是困扰人们的问题。广东省综合单位线法在处理上述两种问题时具有十分重要的意义。文章通过使用杜陵水文站的实测流量资料进行洪水的频率计算与使用广东省综合单位线法求得的结果对比分析,以此来验证广东省综合单位线法计算洪水的精度。With the development of society,the frequency of floods is increasing.Especially in areas with frequent mountain floods,where rivers rise rapidly and converge quickly,precise flood warnings must be made before the arrival of floods.How to determine the scale of floods and make good plans for water conservancy engineering construction has always been a problem that troubles people.The comprehensive unit line method in Guangdong Province is of great significance in dealing with the above two issues.The article compares and analyzes the frequency calculation of floods using the measured flow data from the Duling Hydrological Station with the results obtained using Guangdong Province Comprehensive Unit Line Method,in order to verify the accuracy of Guangdong Province Comprehensive Unit Line Method in calculating floods.
