Abstract:: Land Surface Temperature(LST) is a key parameter in geophysics and is widely used in climatology, hydrology and ecology. Nowadays, many methods have been developed on retrieving LST using infrared bands, and have good results in many arid and humid regions of China. Based on MODIS data, this paper retrieves land surface temperature of Heihe Basin with Mao’s split-window algorithm. The results show surface temperatures of desert and gobi are the highest, surface temperatures of water body and permanent snow/ice are the lowest, which can objectively reflect the climate character in late September in Heihe Basin. According to comparison between retrieving results and measured data in 9 weather stations, the average error is 0.82℃, which is in error allowance of retrieving land surface temperature. So this algorithm is suitable for rapidly retrieving LST of large areas.
