Annual and seasonal mean air temperature and total precipitation were analyzed using Nonparametric statistical test, trend simulate and analysis etc., methods. The results indicate that: The trend shows increasing trend in the past 50 years in Xinjiang, climate warming up mainly in winter which increasing range is 0.47°C/10a (p<0.01), annual average precipitation generally shows increasing trend with the range of 9.23 mm/10a and mainly in summer, but arid grade for heat and humidity situation shows increasing trend. Annual average temperature on spatial, shows a significance increasing trend at stations of 95% among in which the biggest increasing range is in Tianshan mountains, secondly is northern Xinjiang and the smallest is southern Xinjiang. The abrupt change on annual average temperature from cold to warm was happened during 1990-1994 and from more to less on annual average precipitation was happened during 1987-1991.]]>Burn, D.H. and M.A. Hag Elnur,2002255107122Chen, L., L.J.
