The geothermal resources in Tengchong area of Yunnan are rich,and the quantitative prediction and evaluation of geothermal resources is imperative.The retrieval of surface temperature by remote sensing is an important method for the study of geothermal.The ETM data of Band6 thermal infrared channels of a work area of temperature inversion and the eliminate the shadow effect of temperature inversion of correction makes a larger temperature difference between the situation improved,reducing the temperature difference caused by exposure to the sun.The results show that the surface temperature distribution is mainly in three regions,and the 14 -21 degree is selected as the favorable interval for the evaluation of geothermal prediction by the temperature inversion result and the known hot spot overlay analysis.%我国云南腾冲地区地热资源丰富,对地热资源进行定量的预测评价势在必行.而以遥感为手段进行地表温度的反演是地热研究的重要方法.本文利用ETM数据的Band6热红外通道,对工作区进行温度反演并通过消除阴影影响对反演温度进行修正使得温度差异较大的情况得到改善,减少了太阳照射造成的温差影响.结果表明,研究区地表温度分布主要有3个区域;通过温度反演结果与已知地热点叠加分析,选取14 ～21℃为进行地热预测评价的有利区间.
