摘要
本文根据我国东部地区３７５６个重复水准点资料，提出了与我国东部地质构造相结合的新的数据处理思想，分别绘制了我国东部地区陆地与地壳垂直运动速率等值线图。应用地球动力学观点，重点探讨了东部地区的地壳垂直运动特征及其机制，发现我国东部地区（东经１０８度以东）地壳垂直运动总体表现为以地块为单元的拼合构造运动，这些块体的垂直运动速率、倾角年变率及相对应的方位角均不一致，指出这个现象与中国大陆及其周边地区各板块水平运动密切相关。
Based on the adjustment of 3756 bench marks on which repeated leveling has been carried out in two epochs, we obtained the first contour map of quasivertivalmovement rate of Earth's crust in East China under new method of Data processing. On the opinion of tectonics, We had made a detailed research on the crust vertical movement characteristic of eastern China and its mechanism, and found that the vertical movement of eastern China (108°E east) is mainly tectonic matching movement of tectonic units. The units' vertical movement rate, sloping angle and bearing azimuth is related to Indian plate, Eurasia plate, Philippines sea plate and Pacific plate.
