摘　　要：地热资源作为一种清洁能源,得到广泛开采与利用。为服务国家和自治区重大战略和经济建设,保障资源能源安全,推进地热地质研究助力乡村振兴,探明精河县地热资源开发潜力,发展绿色环保经济。采用具抗随机干扰能力强,适用城市密集人口地区灵活作业的地震波频率谐振法进行断裂构造解译。通过分析剖面波阻抗值间的变化趋势及状态,推测断层发育情况及地层岩性、深度、厚度变化情况,查明工作区主要断裂构造空间展布情况。结合水文地质调查、遥感、同位素(C14)等判别依据,圈定2处地热前景区,分别位于精河县黑山头和蘑菇村一带,为后续精河县地热地质钻探实施提供科学地质依据。As a kind of clean energy,geothermal resources are widely exploited and utilized.In order to serve the ma-jor strategic and economic construction of the country and the autonomous region,ensure the security of resources and energy,promote geothermal geological research,help rural revitalization,explore the development potential of geother-mal resources in Jinghe County,and develop a green and environment-friendly economy;The seismic wave frequency resonance method with strong anti random interference ability and flexible operation in densely populated urban areas is used to interpret the fault structure.By analyzing the variation trend and state between the section wave impedance val-ues,the fault development and the variation of formation lithology,depth and thickness are speculated,and the spatial distribution of main fault structures in the working area is found out.Further combined with hydrogeological survey,re-mote sensing Isotope(C14)and other discrimination basis,delineate two geothermal front scenic spots,which are locat-ed in heihatou and mushroom village,Jinghe County;Provide scientific geological basis for the follow-up implementa-tion of geothermal geological drilling in Jinghe county.
