摘　　要：对于南海地层横向磁化率变化较大的地区,以往的常磁性界面反演方法失去效果,为解决类似的磁界面深度反演问题,本文通过对常规磁界面迭代反演方法进行改进,获得基于磁性识别的自适应和变磁性磁界面的迭代反演方法,构建多种模型进行界面深度反演计算,通过对比计算结果,对该方法进行验证,为后续的相关研究提供一定的理论依据。The stratum lateral magnetic susceptibility changes greatly in South China Sea,so the inversion method of the previous magnetic interface had no effect.In order to solve the problem,this paper makes improvements on the iterative inversion method of the conventional magnetic interface and obtains the iterative inversion method of the self-adaptation and variable magnetic interface based on magnetic recognition.In addition,it builds kinds of models to make inversion calculation on the depth of the interface.Comparing the results,it testifies the method and provides a reference for the future related research.
