摘　　要：本文针对阿尔金山东段山间盆地独立水文单元第四系松散沉积层地下水的赋存位置与空间分布规律展开研究.在区域范围内首先采用遥感影像数据划分区域构造与水文地质单元;然后按地质规律设计10条音频大地电磁测深剖面,其中长剖面4条,分别是沿地下水径流方向1条,垂直径流方向上、中、下游剖面3条,最后综合长剖面纵横向地电特征和区域水文地质条件,推测地下水补给来源、地下运移通道、富集区、排泄区和第四系沉积中心及其形态.经钻孔资料验证,本次工作查明了地下水开发利用资源区与重点区域,为下一步工作与规划提供了科学依据.Location and spatial distribution of groundwater in Quaternary loose sediments of independent hydrological units in intermountain basins in the eastern part of Altun Mountains are studied in this paper.In the regional scope,firstly,remote sensing image data is used to divide the regional structure and hydrogeological unit,secondly,10 audio frequency magnetotelluric sounding profiles are designed according to the geological laws,including 4 long profiles,one along the groundwater runoff direction,and 3 upstream,middle and downstream profiles along the vertical runoff direction.Thirdly,based on the vertical and horizontal geoelectric characteristics of the long profile and the regional hydrogeological conditions,the authors concluded the position of the groundwater recharge sources,underground migration channels enrichment area,drainage area,Quaternary sedimentary center and its morphology.Verified by drilling data,this work has identified the groundwater development and utilization resource areas and key areas,providing a scientific basis for the next step of work and planning.
