摘要
根据北京西山若干新构造运动的标志及其地质年代测定资料，将该区新构造运动划分为“喜山期”和“西山期”两个阶段及其相应的１５个新构造幕（Ｈ１—Ｈ５和Ｗ１—Ｗ１０）。新生代以来，西山区新构造运动以不均衡的垂向差异性上升运动为主，兼有掀斜运动、断裂运动和水平运动。地壳运动以总体隆升背景上的脉动升降为特点．
he time of neotectonic movement in Western Mountain area is divided into two poriods: the Himalayan period and Western Mountain period and their corresponding 15 neotectonic episodes (H1-H5 and W1--W10) according to some neotectonic movement indicators and geochronological data. Since the Cenozoic the neotectonic movement in the Western area of Beijing has been dominated by non-isostatic vertical differential uplifting, with many faulting, tilting and horizontal movements between them. The crustal movement is characterized by a general trend to uplifting on the background of pulsational uplift and depression.
