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.
