摘　　要：基于Landsat TM数据,采用单窗算法进行了昆明地区地表温度的反演,获取了地表温度分布图.开展了对研究区热格局的分析,发现昆明地区存在显著热岛效应.通过剖面线分析得到典型区域地表温度变化情况,得出地表温度分布与下垫面密切相关的结论.另外根据水温反演结果和气象资料,初步探讨了滇池水域和城市气候的关系.The land surface temperature inversion of Kunming area is carried out by mono -window algorithm based on Landsat TM data. The picture of land surface temperature distribution is got. An analysis of configura- tion is then made. It is found that there is a significant heat island effect in Kunming. Typical regional land sur-face temperature changes are obtained by a profile line analysis with a conclusion that land surface temperature distribution is closely related to the underlying surface. Additionally, the relationship between Dianchi Lake and city climate is discussed according to the result of water temperature inversion and meteorological information.
