其他摘要：Through spatial analysis of average temperature, annual precipitation in recent 50 years in Xinjiang from the CRUTS2.0 data set and the quantitative analysis of the same climatic factor in recent 22 years from the observation data for 29 observation points in Xinjiang, and by studding the water area change of main lakes, the climate change and its effects to water resources in Xinjiang were presented in this paper. The result shows that the average temperature in Xinjiang has been increased at the speed of 0.6˚C/10asince the end of 1980s, in northern Xinjiang increased at 0.4˚C/10 a，in southern Xinjiang at 1.5˚C/10 ain it; In the same period, the annual precipitation has been increased 55%, in northern Xinjiang increased with a rate of80.9 mm/10a, in southern Xinjiang with54.2 mm/10a; In the spatial charac- teristic of the changes, there are a better coincidence with the increased area of the average temperature and annual pre- cipitation; Analysis on the hydrological data of the same time shows that the warming and wetting climate in Xinjiang is the dominant factor that resulted the increasing tendency for water resources factor, as the water area of main lakes; By comparison the water area of Lake Aibi and the climatic data of Xinjiang, it shows that the water area of Lake Aibi is positively correlated with annual precipitation and average temperature in Xinjiang, the coefficient of the water area between annual precipitation and average temperature are RP = 0.87 and RT = 0.57 respectively.
