The results showed that annual and seasonal average temperature of Zhongning County showed increasing trend overall in recent 57 years, the tendency rate of annual average temperature was 0. 28 ℃10 a, the maximum was 0.47 ℃/10 a in winter, the tendency rate of average maximum temperature was 0.32 ℃/10 a, the tendency rate of average minimum temperature was 0.34 ℃/10 a; annual precipitation and precipitation of spring, summer and autumn all showed decreasing trend, and the tendency rate were -9.34, -3.02, -6.15 and - 1. 32 mm/10 a, respectively; precipitation of winter showed increasing trend weakly, and its tendency rate was 0. 11 mm/10 a. The overall climatic trends were warm and dry, and gradually to the direction of high temperature and drought. Because the changes of climatic, the frequency of weather disasters increased, finally, the effect of climatic change on agriculture and adaptive strategies was analyzed.关键词
