| 摘 要： | 研究了中国大陆地壳垂直运动的特征，提出利用中国大陆现代地壳垂直形变速率图划分活动地块的思路和原则，并把中国大陆划分为东西2个Ｉ级地块，东北、华北、华南、西藏、甘青藏和新疆6个Ⅱ级地块和16个Ⅲ级地块．本文划分的活动地块边界与新构造活动的图象在总体上是一致的，局部地区有些差别．这表明，中国大陆地壳现今活动是第四纪以来新构造活动的继续，但也出现了一些新的活动趋势．

| Abstract: | WT5BZ]The characteristics of vertical crustal movement in Chinese mainland is studied, and the ideas and principles for dividing active blocks according to the Map of Recent Vertical Crustal Deformation Rate in China is proposed. As a result, Chinese mainland is divided into 2 first grade blocks, the east and west block, 6 second grade blocks, the Northeast China, North China, East China, Xizang (Tibet), Ganshu Qinghai Xizang and Xinjiang block, and 16 third grade blocks. The boundaries of active blocks divided in this paper are generally consistent with the pattern of neotectonic movement with some local difference. It shows that the recent crustal activity in Chinese mainland inherits the neotectonic movement occurred since the Quaternary, while some new activity tendencies appear. |
