摘　　要：地热资源是宝贵的可再生能源,它不仅能节省能源,还可以减少环境污染、减少碳排放,有利于生态环境保护,近年来在国内得到了充分的开发利用。通过上黄旗—乌龙沟构造岩浆岩带地热资源调查研究,在初步了解研究区地层、构造、水化学特征等地热地质条件的基础上,利用可控源音频大地电磁法、土壤氡气测量两种物探技术方法,初步圈定潜在地热资源的分布范围,初步发现了一条规模较大、反演深度较深的断裂构造,推断出地热靶区并确定布井孔位,验证了综合物探手段在上黄旗—乌龙沟构造岩浆岩带中寻找地热资源的有效性,为该研究区地热资源的进一步勘查与开发利用提供了地球物理依据。Geothermal resources are valuable renewable energy, it can not only save energy, but also reduce environmental pollution and carbon emissions, conducive to the protection of the ecological environment. In recent years, it has been fully developed and utilized in China. On the basis of a preliminary understanding of the geothermal geological conditions in the study area, such as strata, structures, and hydrochemical characteristics, the distribution of potential geothermal resources is preliminarily delineated by using two geophysical prospecting methods: the controllable source audio-frequency magnetotelluric method and the soil radon measurement, a fault structure with large scale and deep inversion depth has been found preliminarily, the geothermal target area has been deduced and the well positions have been determined, the effectiveness of comprehensive geophysical method in searching for geothermal resources in Wulonggou tectonic magmatic rock belt of Shanghuangqi is verified. It provides geophysics basis for further exploration, development and utilization of geothermal resources in the study area. In the meantime, the study area is also a deep poverty village at the provincial level. On the basis of promoting the development and utilization of local geothermal resources, it is of great significance to promote the development of local tourism and related industrial chain and promote the revitalization of local rural development.
