摘　　要：依据测区地下构造条件、电性结构以及地电阻率特征,结合电测深曲线,建立三维有限元模型。通过数值模拟,计算测区内种植西洋参对地电阻率观测的影响形态和幅度。计算结果表明,在扣除地电阻率基准值后,西洋参种植干扰形态和幅度与实际观测值的异常变化较为吻合。In this paper, we established a three-dimensional finite element model according to theunderground structure conditions, electrical structure, earth resistivity characteristics and electricsounding data. Using the numerical model, we calculated the form and amplitude of affection byAmerican ginseng greenhouses. The results show that, after deducting the normal earth resistivityvalue, the affection type and amplitude caused by American ginseng greenhouse are consistentwith the actual observation changes.
