摘　　要：热红外遥感是获取地表热状况信息的一种非常重要的手段,该地表热状况信息从一定程度上反映了地球深部热源的分布。以福建海坛岛—兴化湾滨海地热调查福清工作区为例,利用美国Landsat8卫星所携带的TIRS传感器所获取的热红外影像,通过大气辐射传输方程算法提取地热异常信息,结合地质、气象、高分辨率遥感影像等多重数据,对区域地热异常的分布进行预测,并与野外钻孔温度信息相验证,取得了较好的效果。Thermal infrared remote sensing is a very important approach to obtain the information of the surficialgeothermal condition which reflect the distribution of the deep source of deep heat on earth to some extend.Taking the geothermal investigation of coast in the Xinhua Bay,Haitan island,Fuqing city,Fujian Province for example,thearticle forecasts the distribution of reginal geothermalanomaly by using thermal infrared imagery from TIRS sensor carried by American Landsat8 satellite,extracting the information of geothermal anomaly through atmospheric radiative transmission equation algorithm,andcombined with the data of geology,meteorology,remote sensing image with high resolution,etc.We also verify our forecast with the drilling temperature information in the field and achieve the good effect.
