摘　　要：基于伊和乌素地区CSAMT资料,结合地形地貌、人文电磁干扰条件以及方法的有效勘查深度与收集钻孔验证情况分析,对方法的勘查效果进行了评价。研究表明:研究区地形地貌条件较好、人文电磁干扰可控;方法勘探深度可靠,成果反映的3个电性界面、四层地电结构,与钻孔揭露情况基本相一致,在该地区具有较好的勘查效果。Based on CSAMT data in the Yihewusu Area,and the topography,human electromagnetic interference condition,effective exploration depth and analysis of drilling hole verification,this paper has evaluated the exploration effect of the method.The study result shows that the topography and geomorphology condition in the study area is relatively good and the human electromagnetic interference is controllable.The exploration depth of the method is reliable.The three electrical interfaces and the four-layer geoelectric structure reflected by the result are basically consistent with the situation revealed by the drilling hole.There is a good exploration effect of the method in the area.
