摘　　要：本文从研究视磁化强度填图的基本理论出发,解决了前人反演结果中存在大量负值的问题。本文应用泰勒级数展开导出了磁性层磁场的级数型积分表达式及其相应的频谱式,与Parker公式相比,推导更为简捷;文中提出的立体角窗加精度政正的方法使空间域方法在任意起伏磁性层情况下填图成为可能,从而扩大了方法的适用范围。在秦巴地区应用该方法圈定磁性岩体和确定深部磁性构造等,取得了较好的效果。Abstract This paper describes the basic theory of apparent magnetization mapping, inversion for apparent magnetization in frequency domain and spatia1 domain, test of theoretical model and application of the apparent magnetization mapping method in Qinling-Dabashan region.The theory and thod of inversion are strict and it has solved the problem of numerous negative values that exist in inversion results obtained by previous workers. The application of this method in Qinling-Dabashan region has reached valuable conclusions.
