Abstract As an important ecotype resource, geothermal resource is extremely useful and has good market potential.
With the temperature field of land surface as the object, thermal infrared remote sensing has accumulated abundant
successful experience in geothermal resource survey. In previous geothermal resource survey, land surface
temperature was frequently replaced by thermal infrared spectral radiance or brightness temperature to interpret the
geothermal abnormal area. This replacement, however, is unreasonable in fact. This paper has forecasted favorable
geothermal areas by retrieving land surface temperature with the temperature and emissivity separation algorithm and
interpreting geological structure based on ASTER data as well as analyzing hot water activity and deep gas
characteristics of the earth in Changbaishan volcanic area. The results show that the Tianchi section of Liudaogou-
ChangbaishanTianchi-Zengfenshan fault and the Changbai-Julong section of Changbaishan volcanic ring fault make up
favorable areas for geothermal resource exploration and volcanic monitoring.
