| 热红外遥感是地热资源勘查中的常用技术，对江西寻乌地区的Landsat 8热红外影像采用单窗算法，根据MODIS影像计算大气水汽含量，并逐步获取反演参数，得到地表温度反演结果；利用MOD11_L2地表温度产品对结果进行对比分析，验证反演有效性。通过对已有地热资料和地质构造背景的研究，总结地热形成的有利构造条件，分析地表反演温度与已有地热及断裂构造之间的空间关系，建立地热异常区圈定依据，并剔除假异常，最终在研究区圈定了11个潜在地热异常区，为该区地热勘查提供依据。 |

| Abstract: |
| Thermal infrared remote sensing technology is commonly used in geothermal resources exploration. In this paper, the mono-window algorithm was used to calculate atmospheric water vapor content from Landsat 8 thermal infrared images in Xunwu area of Jiangxi Province, and the inversion parameters were gradually obtained based on MODIS image to produce the inversion results of land surface temperature. The results were compared and analyzed using MOD11_L2 land surface temperature products to verify the validity of inversion. Based on available data and geological structure background of geothermal information, the paper summarized the favorable tectonic conditions for geothermal formation, analyzed the spatial relationship between surface inversion temperature and existing geothermal and fault structures, established the geothermal anomaly zone, and eliminated the false anomalies. Finally, 11 potential geothermal anomaly areas were delineated in the study area to provide the basis for geothermal exploration in this area. |
