针对水库汛期分期常见方法主观性大,分期模糊的缺点,文章探讨基于分形方法以河流径流量为指标因子对广西澄碧河水库汛期进行分期.分期结果为:前汛期是4月13日至6月11日、主汛期是6月12日至8月30日、后汛期是8月31日至10月31日.分期结果与澄碧河水库1963~2011年49年间出现大洪水的时间分布相符.文章以水库上游的河流径流量为指标因子进行汛期分期,为缺乏实测入库洪水资料的水库进行汛期划分提供了参考.

In view of the disadvantages of the subjectivity and treservoir flood season staging in the common method,this paper explores the method of fractal theory for Chengbi river reservoir flood season installments,which is based on river runoff as the index factor.The results indicate that the pre-flood season is from April 13th to June 11th, the main flood season is from August 30th to June 12th, the after-flood season is from August 31st to October 31st. The results of the stage are consistent with the time distribution of the great flood in 49 years of 1963~2011.In this paper, the river runoff in the upper reaches is used as the index factor for flood season staging,which provides a reference for the flood data of reservoir flood data.
