| 摘 要： | 根据中国华北地区断层形变测量资料的系统处理结果和已知构造带的分布 ,给出了该区现今主要块体的活动边界 ,分别统计了不同区带断层垂直运动的平均速率 ,对其差异性进行了对比 ,并结合地震活动的空间分布进行了分析。结果表明 ,不同区带的断层活动差异性显著 ,断层测点分布条带与主要构造带或地震活动带一致时 ,其断层垂直运动的平均速率较高 ;在区块与条带相交或相邻的情况下 ,条带上比区块的断层平均活动速率明显偏高

| Abstract: | In this paper,several areas and zones are outlined on the basis of fault deformation from surveying sites and known geologic structure in North China,and the statistics of average rate of vertical fault movement in different areas and zones is made.The differences and comparison between them are analyzed in accordance with the spatial distribution of seismic activity.The results show that the active levels of the faults are different in different areas and zons. When a zone agree with a main fault belt,a geologic structure belt or a seismically active belt,the average of vertical fault movement will be higher.When a zone crosses or neighbors with an area,the average of vertical fault deformation in the zone will be obviously higher than that in the area.This is an important evidence to determine the nowaday boundary of active land block in North China. |
