摘　　要：电磁法作为地球物理勘探的重要分支,现在已被广泛应用于地下结构成像,并且常和其他物探地质手段联合工作,用来确定地下隐伏地质情况。电磁法的探测深度一直是物探和地质工作者非常关注的问题,本文简要介绍了电磁法的发展,探测深度的定义,以及常用电磁法(频率域、时间域)的探测深度和影响因素,并做了简要总结分析。Electromagnetic method as the important branch of geophysical exploration, has now been widely used in imaging underground structure, and otten joints work with other geophysical and geological means, used to identify hidden underground geological conditions. Electromagnetic detection depth has been the geophysical and geological workers＇ very concerned problem, the electromagnetic method development, probing depth definition, as well as the common electromagnetic method （frequency domain, time domain） of probing depth and influence factors are introduced in this paper, and it is briefly summarized and analyzed.

关 键 词：探测深度 电磁法 频率域 时间域
