摘　　要：以TM、航空热红外扫描和航空彩红外图像上显示的遥感影像特征为依据,结合野外实地调查和温泉分布区色彩信息的增强处理结果,识别提取地热异常区和非异常区。根据已知温泉产出的地质构造条件和地面测温等资料,进行地热异常区综合遥感预测,提出了7处地热异常的有利地段,从而为寻找地热水指出了方向。According to the remote sensing image features displayed on the TM image, aerial thermal infrared scan image and aerial color infrared image, integrated with the field survey and the enhanced processing result of color information in hot spring distribution area, the geothermal normal and abnormal area were identified. Based on the geological structure conditions of known hot springs and ground thermometric data, the comprehensive remote sensing prediction of geothermal abnormal area was carried out. Seven favorable geothermal abnormal areas were put forward and the direction for hot spring exploration was given.
