According to the national weather service Tongchuan city for nearly 50 years (1964-2013) of rainfall measured data, the application of related theory and method of mathematical statistics, Mann-Kendall nonparametric tests, R/S analysis method, linear regression theory, all the methods are used to study these datas. Based on the results of mathematical statistics, analysis of the trends in Tongchuan city nearly 50 years of rainfall characteristics and time-space evolution. The results showed that the rainfall of Tongchuan is distributed unequal, it mainly concentrated in February, rainfall of Winter is lesser. In terms of the annual change, Tongchuan city nearly 50 years of rainfall overall showed a negative growth trend. At the same time, by using Mann-Kendall to Analysis this title we can see that, in 1, 2, 6, 7, 8, 11, 12 months, it showed rainfall increased, at the same time, the most obvious increase was in June. Analysis of the H index, in 1, 3, 4, 5, 6, 9 months they were greater than 0.5, it was showed that rainfall time series with long-term sustainability, changes in future rainfall characteristics can still play an important role in today’s rainfall predict. In this paper, China Tongchuan region for nearly 50 years of rainfall characteristics and trend of rainfall were studied, have discussed the changes in rainfall over the years as well as the possible future rainfall trends, base on this to guide the local economic construction, agricultural development and so on.
