Geothermal resource is considered as a clean and renewable energy, which has the advantages of stable heat supply, low cost and high efficiency. As one of the most significant surface environmental parameters, Land Surface Temperature (LST) can be derived from satellite information or direct measurements. The fault structure is also another important indicators of geothermal resources. In order to study the spatial distribution of these two, based on the Landsat8 OLI data in Nimu area, this article superposed the relationship between LST and main faults. The single-window algorithm method was used to invert the LST, coupled with the interpretation of a combination of an active fault zone characteristics. The results showed that the intersection area of the Yadong-Gulu North-South fault zone and the Yarlung Zangbo suture zone is rich in geothermal resources. Rock fracture along the fault zone, joints and fractures, providing a good place for geothermal activities. In addition, the hidden fault structure in the region has a strong influence on hydrothermal activity, causing a large area of surface temperature anomalies. Mainly through structural and thermal analysis of surface temperature anomalies, the background of regional geothermal identified anomaly geothermal focus areas. Also shows thermal image data of its obtained has visual, image, speed, free from traffic conditions, and many other advantages, in particular, depopulated zone on the plateau geothermal anomaly detection, has an important significance.
