摘　　要：针对乌蒙山重点地区地形、地质、地貌和气候条件复杂及工作条件差、基础资料缺乏等特点,建立了以野外地面调查为主,结合现场钻孔压水试验资料分析、水化学分析、环境同位素测试分析等多手段多方法的水文地质条件综合评价方法,研究了该区的地下水类型、地下水化学特征及其形成条件、主要含水层的分布,地下水补径排条件及其地下水动态变化特征。通过对该区地下水水文地质特征的分析,选择具有供水意义的富水块段进行地下水开发,选建探采结合井和表层泉,从而实现以供水安全为目标的精准扶贫,为研究乌蒙山重点地区的水文地质条件提供了一种新思路。In the region of Wu Meng shan key areas in China,the topographical,geological and climatic conditions are very complicated and the field investigations are also very difficult to be performed. With the consideration of the above reasons and lack of basic data,an integrated evaluation method is developed to study the related hydrogeological conditions of the region,in which field ground surface investigation is mainly adopted with combination of field data analysis of borehole water pressure test,hydrochemical analysis of groundwater from springs,and environmental isotope test,etc.. The hydrogeological conditions of Wu Meng shan key areas are also studied,such as the major types of groundwater and the geochemical properties,the spatial distribution of main aquifers,the relations among supply- runoff- drainage,and dynamic characteristics of groundwater,etc.. By analyzing the hydrogeological characteristics of the area,develop groundwater in meaningful Water- rich Section,build wells for exploration and surface springs,in order to achieve the goal of safe water to poor precision. The research also provides a new way to evaluate the hydrogeological conditions for the region of Wu Meng shan key areas.
