Abstract：Rigid motion model of China continent blocks is established from several period GPS data, and the relative motions among the blocks in China continent is analyzed. Through analysis of the evolution of blocks’ motion, the variation that crustal deformation offset from background field is studied, and its influence on the seismic activity in China coontinent is also analyzed. The blocks in China continent move eastwards generally, and the rate is defferent from each other, in which the rate of Tibet block is the biggest, and it is gradually weaker towards north and east. Compared to western blocks, the directions of eastern blocks show a clockwise rotation. There is a dynamic diffrence between the blocks’ motion in defferent period. As the motion of one or two blocks shows relatively independence, the variation of block motion is not complately consistent.
