Abstract:The characteristics of air temperature and precipitation in Xiangyuan from 1957 to 2010 were analyzed. The impact of local crops was evaluated because of the climate change. The results show that the annual mean air temperature in 54 years was divided into a cold and warm period and rises as 0.3℃/10a. The changing trend of annual mean air temperature is same as the changing trend of the mean air temperature in spring, autumn and winter. But it is opposite in summer. The annual mean precipitation was divided into two rain and two dry period and reduces as -11. 56mm / 10a. The changing trend of annual mean precipitation is same as the changing trend of the mean precipitation in summer and autumn. It is opposite in spring and winter. Climate change has a negative impact on the local crops
Keywords:Air temperature  Characteristics of precipitation  Impact
