摘　　要： 贵州斜坡地带岩溶地区碳酸盐岩裸露,地表水快速下渗漏失,干旱缺水问题突出。同时受深切河谷控制,大部分地区地下水深埋且集中径流,储存空间分布和相互之间连通性高度不均匀,打井找水极其困难,有利蓄水构造导致地下水局部均匀富集,成为打井找水的关键。应急抗旱找水行动中发现向斜核部、背斜翼部、正断层和可溶盐与非可溶岩接触带为最常见地下水富水靶区,比较4种蓄水构造水文地质剖面与电阻率反演剖面差异,总体一致,在分析的地下水径流富集区实施钻井成井率较高。 The carbonate rocks exposed in the karst area of Guizhou slope area,surface water rapid infiltration,drought and water shortage problem is outstanding.Controlled by deep valleys,in most parts of the underground water buried and concentrated runoff,storage space distribution and mutual connectivity between highly nonuniform,water drilling extremely difficult,favorable reservoir structure local uniform groundwater enrichment,become the key of drilling Wells for water.Found in emergency drought water action,normal fault and soluble salt anticline wing and the lava contact zone is the most common underground water in the target area.The relationship between hydrogeological profile and resistivity inversion profile of 4 kinds of water storage structures is compared,and the well drilling rate is higher in the analysis of groundwater runoff concentration area.
