Land surface temperature is a key parameter in the physics of land-surface processes on regional and global scales,combining the results of all surface-atmosphere interactions and energy fluxes between the atmosphere and the ground. It is indispensable to many research fields. Retrieval of land surface temperature by using thermal infrared remote sensing has become one of the most important tasks in quantitative remote sensing. This paper sketched the surface temperature of thermal infrared remote sensing retrieval theory,summarized the methods and key technology of thermal infrared remote sensing retrieve land surface temperature under known land surface emis-sivity,and the difficulties in the current land surface temperature retrieval. Finally,future development trend of the land surface temperature with thermal infrar ed about remote sensing was discussed.
