| 摘 要： | 从正演和反演理论出发, 分别对大地电磁正演和反演方法进行研究。首先论述大地电磁测深正演和反演方法发展现状, 并按照一定的标准对其归类。然后简要阐述不同电磁正演和反演方法的原理, 对比分析不同正演和反演方法的优势、局限性、适用范围以及改进方法。最后通过对正演和反演发展趋势的分析表明, 三维正演研究及全局寻优的非线性反演结合多参数联合反演方法将成为未来的主要发展方向。

| Abstract: | Based on the theory of forward and inversion, forward and inversion methods are studied respectively. Firstly, the magnetotelluric forward and inversion problems are analyzed, and the development and classification of the forward and inversion methods are summarized. Secondly, the principle and procedure of the different methods are described briefly, and the advantages, limitations and enhancement methods are comparatively analyzed. Finally, the trend of the forward and inversion methods are pointed in the future. The three-dimensional forward modeling methods and the global optimization and nonlinear inversion methods will become the main development trend. |
