摘要： 本文通过公元250年修建的引水工程——车箱渠的考证及其现今遗留的风口地形、永定河道变迁、人类活动遗迹和埋藏泥炭沼分布规律的讨论,指出北京地区近代构造运动以北西西向延伸的隆、凹相间的差异升降活动为其特征。破坏性地震就发生在这些北西西向断裂的端点或与活动性强烈的北北东向夏垫断裂的交汇部位。

Abstract: Based on archaeological, geological and geomorphological studies as well as seismic activities recorded in the Beijing region this paper discusses recent crustal movements and gives the following conclusions.[1] Recent crustal movements are characterized by the block-differential movement controlled by the NWW sinistrally trending fault and the NNE dextrally trending fault. [2] The stress field in the Beijing region coincides with the recent regional stress fieldof North China. [3] There has been marked changes in the faulting since Late Holocene, namely, beforethe Warring States Period (475-221 B.C.) the NNE trending fault was predominantwhile beginning from the Liao-Jing dynasties (907-1125A.D.) the NWW trending fault was prevailing. [4] Pleistoseismic activities are related with the NWW running structures.
