Abstract:: Monthly and annual average precipitation and temperature data from 1960 to 2013 were used to study the variation trends of average temperature and precipitation on annual-scale and seasonal-scale in recent 54 years. The linear regression method, accumulative anomaly method and Mann-Kendall method and inverse distance weighted (IDW) interpolation were used in this study. The results were as follows. The annual average temperature varied between 6.2℃ and 9.0℃, and the annual average temperature rose gradually in fluctuation. The climate increasing trend rate was 0.32℃/decade over the recent 54 years, and the abrupt change in temperature occurred in year 1965 and year 1977. Those annual average temperatures were interpolated using inverse distance weighted (IDW) interpolation to reveal their spatial distributions. The results showed that the annual average temperature varied between 0.95℃ and 14℃ at each meteorological station. The temperature trend decreased from southern Xinjiang to northern Xinjiang, and the highest temperature was observed in southern Xinjiang, followed by Tianshan Mountains, and the lowest temperature occurred in northern Xinjiang. The annual precipitation varied from 93.20 mm to 205.80 mm,and the annual precipitation showed an increase trend in recent 54 years,which increased by 8.23 mm/decade. The abrupt change in precipitation occurred in 1963, 1975, 1978 and 1980. The IDW results showed that the annual precipitation varied from 34.20 mm to 261.00 mm at each meteorological station. The highest precipitation was observed in the northern Xinjiang, and then the next high precipitation occurred in the Tianshan Mountains of Xinjiang. The lowest precipitation occurred in the southern Xinjiang.
