With the angle domain overlay method, the apparent resistivity anomaly produced on pure landform was obtained; by adopting the ratio method, topographic correction was made for high density resistivity measuring data under the condition of slope topography; 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.
