摘　　要：选取南四湖流域相关水信息资料,利用水文统计等方法,分析了南四湖主要入湖河流干支流、入湖河流与湖区的洪水遭遇频率。研究发现:河道支流发生5a一遇、10a一遇、20a一遇降雨时,遭遇到其干流相应洪水标准分别为4a一遇、7a一遇、10a一遇洪水;入湖河流发生5a、10a、20a一遇洪水时,与相应的上、下级湖湖水位同频率。Relative hydrological information data of Nansi lake valley was selected.It adopted hydrological calculation,statistical analysis and other methods comprehensively to analyze the flood coincidence probability of main stream,tributary and the lake area.The results found that when river tributary occur flood of 1/5,1/10,1/20,the relative main stream will occur precipitation of 1/4,1/7,1/10.When the river which is into the lake occur flood of 1/5,1/10,1/20,the relative water level of the superior and lower lake is the same frequency.
