Abstract：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.
