摘　　要：在新疆阿克苏地区水文地质调查基础上,根据当地地形、地貌条件,采用EH-4型电导率成像系统,在研究区域内做了面积性的水文物探工作,结合水文地质与地球物理场特征,根据剖面上纵横向电性特征以及深度切片资料,在当地的地质条件下,从水文地质的角度分析当地地下水赋存位置、理深和类型,并查明地下水资源可开发利用情况,根据电阻率值的变化圈定和保护低矿化度地下水层位与区域,并指出可重点关注的区域,为当地政府规划解决人畜饮用高矿化度地下水问题提供了科学的依据.Based on hydrological geology survey in Aksu Xinjiang, and conditios of to the terrain,and physiognomy, we have done a lot of hydrological geophysical research with EH-4 electric conductivity imaging system in the region. Combined with the local hydrological geology and geophysical features, in view of the longitudinal and transverse electricity features on the section plane and slice with the depth imformation of the work area, based on the local geological conditions, we analyzed the bed position, depth and type from the point of hydrologic geology, and find out the exploitable condition of the groundwater resources. Resistivity value changes have laid foundation for delineation and protection of the low mineralization groundwater horizon or area, and for pointing out the important areas to be paid attention. Scientific basis is provided to local government plan, which can solve the problem that people＇s drinking water if of high mineralization.
