摘　　要：近年来,大地电磁法作为深部找矿与地球电性探测的感应类电法有了迅猛的发展,国内电磁法仪器基本上都是美、加、德三国地球物理公司所生产,中国已进口了几百套这些设备.随着中国国力的增强,地面电磁探测系统的自主研制被提到议事日程.从2010年开始,中国科学院地质与地球物理研究所牵头,联合中科院院内及高校等单位在国土资源部探测技术与实验研究专项(SinoProbe)中承担了《地面电磁探测(SEP)系统研制》项目的研究,目前已取得阶段性成果.本文详尽地论述了大地电磁法仪器发展现状、系统研究目标和总体设计,SEP发射系统、感应式磁传感器、分布式电磁数据采集系统、3DEM数据正反演成像软件和可视化数据管理软件、SEP系统集成和野外测试结果,最后对地面电磁探测系统研究进行了讨论、总结和展望.In recent years, the magnetotelluric （MT） method develops rapidly. The MT instruments are almost monopolized by several big geophysical companies from the United States, Canada and Germany, and China has imported nearly 500 sets of these devices. With increasing of national strength, electromagnetic exploration system development independently is on the agenda. In the year of 2010, the Institute of Geology and Geophysics, Chinese Academy of Sciences, took on one subject of the SinoProbe project, the research of surface Electromagnetic Prospecting （SEP） system, and has obtained some achievements. This article presents in detail research of the SEP system, such as objectives and the overall design of the SEP system, the transmitter, the receiver, the coil and the software of the system, as well as test results in the field. Finally, this paper makes discussions, summary and outlook of this system.
