Abstract
For the geothermal area in the southern part of Gongchangling, Liaoyang City, Liaoning Province, China based on ENVI 5.1 software, Aster thermal infrared remote sensing data was used for surface temperature retrieval. Based on the split windowing algorithm, the ground temperature retrieval result graph is finally obtained. According to this analysis, the temperature in the study area is mainly concentrated at 23-28°C. The average temperature is approximately 22°C. The minimum temperature is 12°Cand the maximum temperature is 35°C. The low temperature area is mainly near the Tanghe River and the Taizi River Basin in the study area. High-temperature areas are concentrated in the eastern fringe, where a large number of urban buildings are presented. The three hot springs are located in the study area, which is the high temperature area. In addition, the high temperature zone and the fracture structure in the study area have a large degree of fit.
