Abstract On the basis of the GPS data of Chinese Crustal Motion Network in North China, the velocities and the strain rates on blocks in North China were calculated, as well as these on block’s boundary fault zones. The North China subplates’ motion and features of the strain rate, and also the features of the strain stress of the block’s boundary fault zones were studied. The results show that the direction of the westeast movement field of North China subplates turns from east to southeast, the NENNE fault zone is of rightlateral strike slip activity and the NWWEW fault zone is of leftlateral strike slip activity. The directions of the principal compressive strain axis of the subblocks are different. The present strain of the block’s boundary fault zones indicates that the force of the north part of Tanlu fault zone and the Shanxi downfaulted zone is mainly compressive, the strain energy is accumulating, but the strain rate is small, the speed of the accumulation is slow, so we should pay attention to the variation in future.
