英文摘要：

In the interpretation of geophysical data processing, the phenomenon of anisotropy is the important factor that cannot be ignored. In the anisotropy medium, the forward modeling of magnetotelluric has always been the forefront subject in the field of electromagnetic induction at home and abroad . The paper aims to briefly introduce the development of forward modeling and several major research methods. Additionally, the paper also probes into the research directions, difficulties and challenges of magnetotelluric in the anisotropy medium.
