摘　　要：为了使尼尔基水库防洪与兴利相协调,开展水库汛期分期研究。以逐旬降水量、25mm以上降水量级、1至3日最大降水量、逐旬流量、洪峰流量等为指标,采用长系列数据,分析暴雨、洪水在汛期内的变化规律,确定前汛期、主汛期和后汛期的分期时间分布。为确定汛期分期的合理性,以日降雨量、日入库流量为指标,采用模糊统计法进行检验,同时结合尼尔基水库实际运行,提出了合理汛期分期时间。为管理部门调控尼尔基水库防洪、兴利提供了依据。In order to better coordinate flood control and benefit promotion of Nierji Reservoir,the study on flood season staging of the reservoir is carried out.Taking the ten-day precipitation,the precipitation above 25 mm,the maximum precipitation from 1 to 3 days,the ten-day flow and the peak flow as the indicators,and using a long series of data,this paper analyzes the change law of rainstorm and flood in the flood season,and determines the time distribution of the pre-flood season,the main flood s eason and the post-flood season.In order to determine the rationality of the flood season division,the daily rainfall and daily inflow are taken as the indicators,and the fuzzy statistical method is used to test the reasonableness of the flood season division.Combined with the actual operation of Nierji Reservoir,the reasonable flood season division time is proposed.It provides the basis for the management department to regulate and control the flood control and benefit of Nierji Reservoir.
