摘 要: 深部电磁感应研究可以提供地下几百千米直到核幔边界的电导率分布信息,是地球构造、演化以及动力学研究中一种非常重要的地球物理手段,一直以来都是国内外研究的热点.本文拟从深部电磁感应的基本理论、正演模拟、数据处理及反演等三个方面,介绍几十年来国内外学者的研究成果,总结目前深部电磁感应研究所遇到的困难,并对其未来的发展提出建议.本文旨在使读者了解深部电磁感应研究的现状以及未来的发展方向和热点,以期推动该技术在我国得到进一步的发展和应用. As a hotspot both at home and aboard,deep electromagnetic induction is a significant geophysical tool to study the structure,evolution and dynamics of the Earth,because it can provide information of conductivity from a few hundred kilometers down to the core-mantle boundary.In this paper,we present the basic theory,numerical modeling,data analysis and inversion of deep EM induction,introduce the achievement of national and international experts,summarize the problem it is facing and give our suggestions about its future.Our goal is to make readers enhance awareness of deep EM induction study's current situation and future direction,and look forward to promoting its development and application in China.
