通过角域叠加的方法获得由纯地形引起的视电阻率异常，采用比值法对边坡地形条件下的高密度电阻率法测量数据进行地形校正，并结合测区钻孔地质剖面分析地改效果。结果表明：角域地形改正的方法是有效的，地改后的反演断面与实际的地质情况更加接近，效果较好。

With the angle domain overlay method, the apparent resistivity anomaly produced on pure landform was obtained;by adop-ting the ratio method, topographic correction was made for high density resistivity measuring data under the condition of slope topogra-phy;in combination with the drill hole geological sections in the surveying area, the effects of the topographic correction were analyzed. The results show that the method of angle domain topographic correction is effective, as is shown by the facts that the inverse sectional drawing after the topographic correction is closer to the practical geological situation, and the effects are fairly satisfactory.
