摘　　要：简述了辽宁地区地球物理场监测地磁测网的改造情况;利用改造后测网观测成果,分别绘制了辽宁地区地磁场总强度梯度分布图、地磁场总强度等值线分布趋势图及地磁场年变化分析图:探讨了改造后的地磁测网地磁场梯度分布规律;分析了辽宁地区各重要活动断裂及老震区地磁场总强度的年变化和邻期变化特征,为地震预报提供服务支撑。This paper resumed the reconstruction of the geomagnetic network at the geophysical field in Liaoning. Based on the observation data after reconstruction, the gradient distribution and the total geomagnetic intensity isoline distribution trend map are drawn. The gradient distribution law of the geomagnetic network after reconstruction has been discussed. The annual variation and the adjacent variation features of the important active faults and the old seismic zone in Liaoning are analyzed, which could provide support for the seismic prediction.
