摘　　要：物探数据反演的多解性给资料处理和解释造成了一定的困难,而等效源法正是利用了反演的多解性,通过对等效源的密度进行反演得到地下真实的场源。采用棱柱体等效源,对三维理论模型重力异常进行反演成像计算和分析,并运用实际重力资料进行了计算和处理。理论和实践证明效果良好,表明了等效源反演在重力测量中的可行性和正确性。The multiple solutions of inversion cause some difficulties in geophysical prospecting data processing and interpretation. However, the equivalent source method just uses the multiplicity of solution through inversing the density of equivalent sources to obtain the real field underground. By using the prism as equivalent source, we calculated and analyzed the inversion imaging for the gravitational anomaly of theoretical 3D model, used the real gravity data to conduct calculation and processing. Good results were demonstrated theoretically and pratically, showing the viability and correctness of the method.
