According to the routine meteorological data of Wafangdian City from 1957 to 2012 ,the variation of the temperature and precipitation in Wafangdian City was analyzed.The results showed that the annual average temperature in Wafangdian City was on the rise tendency as a result from the contribution of the temperature rise in spring and summer.It also showed that the rise range of the annual average minimum of temperature was more than that of the annual average maximum temperature.Besides ,the sudden change of the annual average temperature happened in 1988.The annual precipitation was on the rise tendency.The precipitation in spring was on the increase and that in the other seasons was on the decrease.The differences of the monthly precipitation were obvious.
