摘　　要：电磁波层析成像是一种发展中的地球物理勘探技术,主要分为电磁波走时层析成像技术、电磁波衰减系数层析成像技术和电磁波相位层析成像技术,这些方法已广泛用于金属矿、非金属矿、石油天然气、工程地质与水文的勘察。介绍了电磁波层析成像中电磁波走时、电磁波衰减系数和电磁波相位三种层析成像方法的理论基础和研究现状,分析了电磁波反演图像重建技术及其在内外的实际应用现状,对电磁波层析成像技术的发展趋势进行了展望。Electromagnetic tomography is an effective geophysical exploration technique, which can be grouped into three categories： travel--time tomography, attenuation tomography and phase tomography. It can obtain the image of position and geometry of target through computer processing, and has been widely used in metal and nonmetal minerals, petroleum, engineering and hydrologic geology prospecting. This paper first introduces the basic theory and development of electromagnetic wave travel-time tomography, attenuation tomography and phase tomography, then elucidates the development of image reconstruction and its application. Finally the tendency and further study of electromagnetic tomography are proposed.
