摘　　要：针对传统的水库汛期分期方法主观性大且分期判定指标因子单一的问题,基于分形方法,以降雨量为指标对澄碧河水库汛期进行了分期。在分期前,先根据流域历史日均降雨量确定水库汛期的起讫时间,再根据分形的聚类性确定水库分期的数量。结果表明:澄碧河水库汛期为4月13日—10月31日,其中前汛期为4月13日—6月6日、主汛期为6月7日—8月25日、后汛期为8月26日—10月31日。In order to solve the problem of traditional method of reservoir flood season staging of subjectivity and single index factor of staging deter-mination,this paper explored the use of fractal theory in rainfall of the index factor on Chengbihe Reservoir flood season. In the staging process,ac-cording to the reservoir historical average daily rainfall,it determined the reservoir flood season start and end time and determined the number of in-stallments of the reservoir based on fractal clustering. The results indicate that the flood season of Chengbihe Reservoir is from April 13 to October 31,of which,the early flood season is from April 13 to June 6,main flood season is from June 7 to August 25 and late - flood season is from August 26 to October 31.
