摘　　要：为加强备用水源地建设,科学管理备用水源地资源,实现水资源可持续利用。文章以云南保山市孟官岩溶备用水源地为研究对象,利用水均衡理论及质量守恒定律进行水源地地下水资源评价;基于研究区水文地质条件,运用Arcgis软件实现地质模型三维可视化,直观体现岩溶地下水流通道,结合含(隔)水层水文地质参数,构建合理水文地质概念模型,建立与实际地下水位误差2 m范围内的三维地下水流场,预测流场变化;确定正常降水年取水方案为泉采供水,开采量小于允许最大开采量即可,枯水年采用井采辅助泉采方式供水,正常、连续枯水年供水井的开采总量分别为12419.22 m^(3)/d、11674.49 m^(3)/d,而泉采量则应小于39974.02 m^(3)/d;同时针对开采井位置及开采量划定一级、二级保护区面积分别为12.64 km^(2)、42.37 km^(2),并提出了对应保护措施。In order to strengthen the construction of alternate water sources,scientifically manage the resources of alternate water sources and realize the sustainable use of water resources,the article,taking Mengguan karst backup water source in Baoshan City,Yunnan Province,as the research object,the water balance theory and the law of mass conservation are used to evaluate the groundwater resources in the water source;based on the hydrogeological conditions of the research area,Arcgis software is used to realize the three-dimensional visualization of the geological model,which visually embodies the karst groundwater flow paths,and combined with the hydrogeological parameters of the water-bearing layer,the conceptual hydrogeological model is constructed to establish the reasonable hydrogeological conceptual model,and sink term is used to establish the three-dimensional groundwater flow field within the range of 2m error from the actual groundwater level to predicting fluid flow changes.It is determined that the water extraction program in normal precipitation year is spring mining for water supply,and the extraction volume is less than the maximum permissible extraction volume,and in dry water year,the water supply is carried out by well mining and auxiliary spring mining.The total amount of extraction from wells for water supply in normal and continuous dry water year is 12419.22 m^(3)/d and 11674.49 m^(3)/d,respectively,while the spring extraction should be less than 39974.02 m^(3)/d;Meanwhile,the area of the first-level and second-level protection zone for the mining well location and production volume is designated as 12.64 km^(2)、42.37 km^(2),and corresponding protection measures are proposed.
