摘　　要：在近年来国内外地球电磁学者的研究基础上,从大地电磁测深法的正演和反演理论出发,对目前常用的三维正演和反演理论进行简要阐述,总结了当前大地电磁测深法三维正演和反演的研究成果,分析了目前主流方法的优缺点及其应用局限性,最后对发展趋势进行了讨论。由于地球物理反演存在多解性,提高反演精度将成为今后的一大热点问题,利用其他地球物理勘探方法与大地电磁测深法相结合进行多参数三维反演,可提高三维反演的可靠性。With the domestic and foreign geoelectromagnetists preceding researches,this paper briefly introduces the research progress of the current commonly used three-dimensional forward and inverse in magnetotelluric sounding.Firstly,we summarize the achievement of three-dimensional forward modeling and inversion of magnetotelluric sounding.Then,the advantages and disadvantages of mainstream three-dimensional forward and inverse methods and their application limitations are analyzed.Finally,the development trend of magnetotelluric sounding three-dimensional forward and inverse is discussed.Due to limitation of multiple solutions in geophysical inversion,improving the accuracy of inversion has become a hot issue.The reliability of three-dimensional inversion can be improved by combining other geophysical exploration methods with magnetotelluric sounding for multi-parameter three-dimensional inversion.
