摘　　要：通过对"90%降雨事件法"进行改进,优化降雨频率计算表,得出适合滇池流域的"降雨事件法",用于确定不同污染控制目标下的初期雨水截流量。并以滇池流域为例,通过计算发现,要实现滇池流域全年初期雨水截流量达到50%总降雨量的目标,累积频率P取65.67%,初期雨水截流厚度为9.7 mm。该方法亦能推广应用到全国其他地区。Through improving ＂90% rainfall event method＂ and optimizing calculation sheet of rainfall frequency, an appropriate ＂rainfall event method＂ could be achieved to calculate interception ca- pacity of initial rainwater for different targets of pollution control in Dianchi Lake Basin. Setting Dianchi Lake Basin as an example and through calculating, to achieve the goal of 50% interception capacity of in- itial rainwater in Dianehi Lake Basin, the cumulative frequency P should be set as 65.67%, and the cor- responding interception capacity of initial rainwater should be set as 9.7 mm. This method can be applied in other places in China.
