本文介绍了江苏地区地磁(F、Z)观测台网的情况。对台网观测资料的精度进行了讨论。最后,为了探索与研究震磁关系,作者对以下问题阐述了自己的看法: 1、为捕捉地震前磁异常,有必要在地震监视地区建立简易的、长期的、密集的地磁台网; 2、在中低纬度地区应重视地磁垂直分量(Z)观测。 This paper introduces the geomagnetic (F, Z) observation network in Jiangsu Province. The accuracy of the observation data of Taiwan Network is discussed. Finally, in order to explore and study the relationship between magnetism and magnetism, the author expounds his own views on the following issues: 1. To capture the pre-seismic magnetic anomalies, it is necessary to establish a simple, long-term and dense geomagnetic network in the seismic surveillance area; Geomagnetic vertical component (Z) observation should be emphasized in the middle and low latitudes.
