Abstract： Based on the monthly precipitation data of Guichi rainfall station in Chizhou City， Anhui Province in East China for 69 years， a variety of precipitation change and catastrophe analysis methods are used to analyze and study. The results show that the precipitation of Chizhou City in 69 years shows a non significant increase trend from the overall observation. From the interannual sequence observation， it can be found that there is no mutation in the four seasons except spring， and there are mutations in individual years in other seasons.

Keywords： precipitation; change trend; mutation analysis
