摘　　要：地下水资源的勘探和管理对于确保水资源的可持续利用至关重要。茫崖市尕斯库勒湖流域紧邻昆仑山前冲积扇,地下水资源相对丰富,加强该地区淡水资源勘查,对于维持区域内生态环境的可持续性发展具有重要意义。高密度电阻率法作为一种有效的地球物理勘探手段,在地下水勘查领域展现出了其独特的优势,与传统电阻率法相比高密度电阻率法具有更高的空间分辨率和数据采集效率,能够更精确地识别地下结构和含水层。文章主要介绍了高密度电阻率法的技术原理、方法和在尕斯库勒湖地区地下水勘查中的应用实例,在对研究区地质地貌和水文地质结构进行分析的基础上开展高密度电阻率法的工作,利用现场勘测的数据进行反演处理,为判定含水层位置、地层变化提供可靠的物探资料依据,对同类型地区使用该方法勘查水资源具有一定的指导意义。The exploration and management of groundwater resources are crucial for ensuring the sustainable utilization of water resources.The Gaskule Lake Basin,located near the alluvial fan in front of the Kunlun Mountains in Mangya City,is relatively rich in groundwater resources.Enhancing the exploration of freshwater resources in this area is crucial for ensuring the sustainable development of the regional ecological environment.As an effective geophysical exploration method,the high-density resistivity method has shown its unique advantages in the field of groundwater exploration.Compared with the traditional resistivity method,the high-density resistivity method has higher spatial resolution and data acquisition efficiency,and can more accurately identify underground structures and aquifers.This paper mainly introduces the technical principles,methods,and application examples of the high-density resistivity method in groundwater exploration in the Gaskule Lake area.Based on the analysis of the geological landform and hydrogeological structure of the study area,the work of the high-density resistivity method was carried out.The inversion processing was conducted using the field survey data to provide a reliable basis for geophysical exploration data for determining the location of aquifers and stratigraphic changes.The application of this method in similar areas for water resource exploration has certain guiding significance.
