摘要
以柴达木盆地新构造运动发生的期次、黄河兰州谷地出现的突出构造事件、阿尔金断裂带第四纪所经历的大运动阶段、攀西裂谷区新构造运动分期、北京地区南段新构造运动波动、全国一些地区断裂活动时序等为例证，再次证明了第四纪以来中国大陆地壳活动具有明显的时段性，４次强烈的构造活动分别发生在上新世末至早更新世初、早更新世中晚期、中更新世中晚期和全新世。其中，以中更新世中晚期地壳活动强度最大、波及范围最广。
From the time series of neotectonic movement of the Qaidam Basin, the main neotectonic events of the Yellow River valley in Lanzhou,the main active stages of the Altun fault zone and time series of some faults activity throughout the country, this paper discusses the time and process of Quaternary crustal movement of the Chinese continent once again and gives the following conclusions:(1) The characteristics of the time and process of Quaternary crustal movement of the Chinese continent not only occur in the time series of the volcanic activity of the Chinese continent ,uplifting of the Qinghai Tibet Plateau, deformation of the Loess Plateau and faulting in the Three Gorges area of the Yangtze River and it's adjacent areas during the Quaternary, but also exist in the time series of neotectonic movement of the Qaidam Basin ,in the main neotctonic events of the Yellow River valley in Lanzhou, in the main active stages of the Altun fault zone and Quaternary activity of some faults throughout the country. (2) Although source materials are obtained from different regions, and they represent different crustal movement forms, their time series of activity are mainly consistent. (3) The Quaternary crustal movement of the Chinese continent are marked by an obvious rime span characteristic, Since the Early Pleistocene, there have been four times of tectonic movement(the initial Early Pleistocene, the middle Early Pleistocene, Middle Pleistocene and Holocene), of which the Middle Pleistocene tectonic movement is the strongest.
