Based on 60 years' data from 22 hydrological stations in China, the dynamic changes of precipitation and temperature are analyzed by statistical method, and the correlation between precipitation and temperature was evaluated comprehensively. The main conclusions are as follows: a. Precipitation shows fluctuation in recent 60 years in China.It increases in some years and decreases in the other years, without the unified changes.b. The temperature change also has been in fluctuation.During the recent 10 to 20 years, the date from most hydrological stations shows increasing trend, but the data of some hydrological stations have shown the decreasing trend.So, it is hard to obtain a conclusion of global uniform warming.c. From the interrelationship between precipitation and temperature, in some periods or years, there was more precipitation with lower temperature, but the opposite situation also existed. Accordingly, it is difficult to draw a conclusion that temperature increase can lead to precipitation uniform increase or decrease.d. The correlativity between precipitation and temperature at most of the hydrological stations did not show significant positive or negative correlation. It shows that precipitation and temperature are likely to be conditioned by some other significant factors respectively.e. From the hydrological and meteorological analysis of China as one part of the world, we cannot conclude that global climate has the trend of changing warm.
