基于天山北麓7个气象站1963~2010年逐月0 cm最高、最低地温资料，采用线性趋势分析、Mann-Kendall检验、Morlet小波等方法，分析了天山北麓地温变化特征。结果表明：（1）近48 a来，天山北麓0 cm最高地温以精河为高值中心，总体上呈西高东低的特征，最低地温以乌苏、乌鲁木齐为高值中心的中西部地区普遍较高；（2）0 cm地温呈显著上升趋势，最低地温增幅尤为显著，达0.87℃/10 a；（3）0 cm最低地温在2002年发生突变，而最高地温未出现突变；（4）0 cm地温异常年份主要发生在2006年之后，以偏暖为主。

Based on the monthly maximum and minimum ground surface temperature on 0 cm soil layer at 7 meteorological stations in northern piedmont of Tianshan Mountains during 1963-2010,the spatial and temporal distributions were analyzed by using the linear trend analysis,Mann-Kendall test and Morlet wavelets. The results showed that the spatial distribution of the maximum ground sur-face temperature decreased from west to east generally,the high value center was in Jinghe of Xinjiang. Meanwhile,the minimum ground surface temperature in central and western regions around Usu and Urumqi was higher than that in other places. In the past 48 years,the ground surface temperature showed a significantly increasing trend in the whole,and the linear climatic tendency rates of the minimum and maximum temperature was respectively 0. 87 ℃/10 a and 0. 46 ℃/10 a,but the fluctuation of the minimum ground sur-face temperature was much more than that of the maximum. In addition,the changes of seasonal ground surface temperature increased significantly during 1963-2010,and the warming trends in winter and autumn were holistically greater than in other seasons. The mu-tation of the minimum ground surface temperature occurred in 2002,while that of the maximum ground surface temperature didn’t pass the significance test. Meanwhile,the ground surface temperature being anomalous warmer occurred since 2006.
