摘要：

Characteristic analysis of rainfall variation can offer technical support to flood prevention. Based on annual precipitation data of eleven major stations in Zhuzhaoxin River Basin from 1964 to 2008, Kendall method was applied to analyze the evolution tendency. Moving t-test and orderly clustering analysis method were discussed with sudden change points. Then spectrum density graph of variance was used to analyze precipitation variation period. The result showed that the variation of rainfall was obvious; the sudden change points occurred in 1976, 1986 and 2002; Precipitation variation periods were three years and seven years.
