Abstract: To explore the content of climate change, climate characteristics of water resources in Xinjiang, based on the meteorological data of 50 stations over the Xinjiang region, was estimated by the empirical formula of the land surface evaporation, and in turn the climate change characteristics and temporal distribution of water resources in Xinjiang area were analyzed by the method of Mann-Kendall test. The results showed that: (1) the precipitation, the average temperature and the evaporation during historical 54 years in the Xinjiang area was detected to increase significantly. (2) the highest value of the precipitation was found in North part of Xinjiang, followed by East and South parts. (3) the annual average temperature was found to increase with a significant trend of 0.03 ℃ per year. (4) The D-value of precipitation in the northern Xinjiang was close to the value of the Xinjiang, and was less than 0 in southern and eastern Xinjiang, which indicated that most areas of southern and eastern Xinjiang was strongly characterized by scare water resource and suffered arid climate through many years. (5) From northern to southern and from western to eastern, the precipitation, evaporation and precipitation deficit decreased, while the average temperature increased.
