摘　　要：地处喀斯特地貌的乌蒙山可乐幅岩溶区地质情况复杂,常规地质填图工作面临较大困难。为了解该区地层结构、构造发育特征及浅部岩溶发育情况,通过大比例尺音频大地电磁法查明地层结构,圈定大规模构造发育特征;利用高密度电法获取浅部电性特征,查明重点部位浅部岩溶发育情况。实践表明,采用组合物探勘查模式,既可提高工作效率,又可以互相印证,在岩溶区地质填图中取得了良好的效果。The karst geological situation in Wumengshan is complex,which leads to great difficulties for geological mapping work.In order to find out the stratigraphic structure,tectonic development characteristics and shallow karst development in the area,firstly,we identify the stratum structure and delimit large-scale tectonic development features by using the large-scale AMT method,and then use the high-density electrical method to obtain shallow resistivity characteristics to identify shallow karst development in key parts.The application of the integration of several methods can both improvethe working efficiency and verify mutually,providing good effect onthe geological mapping of karst areas.
