摘　　要：为提高野外CSAMT测深数据的反演解释效率,基于一维全区反演,提出了CSAMT一维自动迭代与人机联作方式交替反演进行拟二维反演解释的思路。该方法在自动迭代反演中,将BOSTICK反演结果作为自动迭代反演的初始模型。这里详细介绍了该方法的反演流程,并将该方法应用于实际资料的反演,反演结果与钻探资料基本吻合,证实了该方法是有效的。A new way is proposed in the paper to improve the processing efficiency of CSAMT data through using 1D automatic iterative and man-machine interactive inversion by turn. In this way, the results of the BOSTICK inversion is taken as the initial model of our inversion. The inversion flow chart is introduced deeply in this paper. The method is applied to real data and it is found that the inversion results are coincidence with the drilling results. The results show that the method is valid.
