[目的]研究西部大开发、"一带一路"战略推进下带来的乌鲁木齐城市热环境问题.[方法]选取1994年7月16日、2008年8月7日的Landsat-5/TM及2015年7月17日的Landsat-8/OLI_TIRS影像数据,利用单窗算法进行地表温度反演,对反演结果进行空间统计分析,提出从整体至分区的角度分析乌鲁木齐市地表温度时空分布状况,通过对地表温度反演结果归一化处理划分热环境等级,进而研究乌鲁木齐市地表热环境时空变化特征.[结果]整体上,1994—2015年地表温度差异较大,平均温度相差15.08 ℃,最高温度和最低温度相差近30.00 ℃,最低温度变化不大.区域上,新市区、沙依巴克区、天山区地表温度历年来一直居高,最低温度一般分布在水磨沟区和乌鲁木齐县.[结论]乌鲁木齐市中心城区热环境效应较为明显,城市高温区有扩散的显著趋势.%[Objective]The research aimed to study the environment problems of the constant advancing strategy of western development and Belt and Road.[Method]The paper selecting Landsat-5/TM on July 16 in 1994 and on August 7 in 2008 and Landsat-8/OLI_TIRS three scenes image data on July 17 in 2015,using mono-window algorithm to carry out land surface temperature inversion.The inversion results were in spatial statistical analysis, and proposed an angle that from the overall to regional analysis on Urumqi surface temperature distributions of time and space.The results of land surface temperature inversion were in normalization processing to divide heat environment levels,and then the features of land surface thermal environment in Urumqi were studied.[Result]On the overall,the land surface temperature difference dur-ing 1994/2015 was big, and the average temperature difference was 15.08 ℃.The maximum temperature and the minimum temperature difference was nearly 30.00 ℃.The lowest temperature change was not obvious.On the area,the land surface temperature in new urban are-a,Sha Ebak area,Tianshan area had been high over years.The lowest temperature was commonly distributed in Shuimogou area and Urumqi County.[Conclusion]The thermal environment effect in Urumqi City is more obvious, and the city high temperature area has the significant trend of expanding and extending outward.
