摘　　要：从Planck函数和热红外辐射传输方程出发,概述了热红外遥感反演地表温度的基本原理,总结了当前反演地表温度常用到的热红外遥感器及相应波段。将热红外遥感地表温度反演算法分为单通道、劈窗和多通道3大类,分析了每一类中较具代表性算法的原理、适用条件及精确度。从热红外遥感机理、发射率、环境辐射、混合像元、大气影响等方面概述了热红外遥感反演地表温度面临的主要问题,并对热红外遥感地表温度反演的发展趋势进行了展望。Starting from the Planck function and thermal infrared radiative transfer equation,this paper gives an overview of the basic principles of the thermal infrared remote sensing for surface temperature inversion.It also summarizes thermal infrared sensors and the corresponding bands used in the inversion of surface temperature.Algorithms for the inversion of surface temperature are divided into three categories：single channel,split-window and multi-channel,and typical algorithms of each class are analyzed from the view of the principle,applicable conditions and accuracy.The main problems faced by the thermal infrared remote sensing for surface temperature inversion are also summarized from the aspects of the thermal infrared remote sensing mechanism,emissivity,environmental radiation,mixed pixels and atmospheric effects,and the development trend of the thermal infrared remote sensing for surface temperature inversion is further pointed out in this paper.
