In order to reveal the variation characteristics of precipitation in baoji,the paper took. the meteorological observation data as the base in Baoji from 1960 to 2013,and analyzed the temporal variation characteristics of precipitation by using the general linear regression analysis, Morlet wavelet analysis and R/S analysis. The results showed that the precipitation has a general decreasing tendency for 54 years.Precipitation increases in summer and winter, and reduces in spring and autumn. Precipitation shows periodic change trend of different dimensions.The annual temporal scales of precipitation feature are 32,12,6 and 4 years. The seasonal temporal scales of precipitation feature are 4 to 7,10 to 17 and 24 to 32 years.The future variation trend of precipitation will keep consistent with that in the past.The precipitation in annual, spring and autumn will present the trend of decrease,and that in summer and winter will continue to increase.The factors that affect the change of precipitation in summer is the most complicated.
