摘　　要：应用大华北地区最新流动地磁观测资料,对该地区2015.0年代岩石圈磁场空间分布及地震地质特征进行了分析与讨论。结果表明:大华北地区岩石圈磁场具备较强的局部异常特征,其空间分布形态与测区内主要板块具有一定程度的对应关系,而历史地震多发生于一些特殊的岩石圈磁场部位。Based on the latest mobile geomagnetic observation data of North China region, the spatial distribution and seismic geological features of the region＇s 2015.0 lithospheric magnetic field are analyzed and discussed. The re- suits show that the lithospheric magnetic field in North China has the characteristics of strong local anomalies. Its spatial distribution pattern and the main plate in the area have a certain degree of correspondence, and previous earthquakes mostly occurred in some soecial parts of the magnetic field of the lithosohere.
