摘　　要：本文探讨强烈磁暴对地电测量的影响问题。首先从麦克斯韦方程组出发、求解地球对磁暴环流的电磁感应问题、得出地面一点的分量解，进而得到地面上的磁暴效应。其次，由磁暴效应对地电网络的作用得出两个效果，最后根据对固原台资料的分析得到两点认识、可作为地电观测中干扰识别与排除的依据之一。This paper probes into the problem of telluric current prospectunder the influence of strong magnetic storm from Maxwell’s equations,Fi-rst the component solution of a point of the earth’s surface is derived byresolving the problem of the electromagnetic induction of magnetic stormcirculation,Secondly two effects of geoelectric mesh line nfluenced by ge-omagnetic storm effect are obtained from the geomagnetic storm effect ofland surface,Finally from analyzing the data of GUYUAN station, two co-gnitions are obtained,which can be regarded as one of the bases of distur-bance’S identification and preclusion in geoelectric measuring。
