Abstract:Based on the climate and water resources data of Jingzhong , Shanxi Pr ovince for recent 49 years, the change characteristics of temperature, precipita tion and water resources are analyzed. The results indicate that the annual mea n temperature is rising at a rate of 0.3 ℃/10a, and the increasing mainly occur s in winter. While, the precipitation is decreasing at a rate of 35.9mm/10a, wit h the largest decrease in the 1990s. The water resources, groundwater and river runoff all tend to decrease, which are consistent with the changes of precipitat ion.
