摘　　要：针对河北及邻区2013年以来的地震平静现象,依据汶川8.0级、昆仑山口8.1级和日本9.0级地震前后我国M_L5.0以上地震活动空间图像分布特征,结合华北地震第四活动期内华北地区5级、6级地震时序特征,以及日本海沟地震与华北地震的相关统计关系,研究认为,河北及邻区近年的地震平静现象应属于正常的平静时段。In order to study the obvious seismic quiescence in Hebei and adjacent areas since 2013,the spatial image distribution characteristics of M L 5.0 seismic activity in China before and after the Wenchuan 8.0 great earthquake,the Kunlun mountain 8.1 great earthquake and the Japan 9.0 great earthquake are summarized combining with the sequence characteristics of the M 5 and M 6 earthquakes in North China during the fourth activity period and correlation statistical relationship between Japanese Trench earthquake and North China earthquake.The result shows that the seismic quiescence is a normal quiet period of seismic activity of Hebei and adjacent areas.
