摘　　要：地磁异常与地震相关性研究是一个较为活跃的领域。马边台地磁Z分量表现出较明显的映震现象。其表现为:(1)“低点位移”在时间领域分布异常;(2)瞬时差幅度异常;(3)日变形态畸变。本文以马边台23年的地磁资料,以成都地磁台为参照,从以上三方面进行了分析和总结,得到单台地磁预测地震的一些有益的启示。Basing on the geomagnetic data for 20 years observeo from Mabian Seismic station , we think that there is a clear interrelated relationship between the geomagnetic vertical intensity around Mabian seismic station and the seismicity around. The relationship between the geomagnetic anomaly and earthquakes is an important research branch.First, the precursor of the low point movement appears in the time domain. Second, the shortterm change of geomagnetic data is considered as a precursor. Last, the daily change of the geomagnetic data shows an irregular change status.
