%X The seismic fault parameters can be inversed with Okada model based on the deformation data before and after earthquakes in the focal region and its adjacent area.Co-seismic displacements are simulated by use of these parameters and then the regional velocity field is obtained by deducting the co-seismic displacements from the GPS observation displacements.We processed and analyzed the data in northeastern margin of the Qinghai-Tibet plateau observed during 2001-2003 in two steps: firstly,simulated the displacements generated by Kunlun Ms{8.1 earthquake occurred in 2001 in this region,and then obtained the horizontal crustal velocity field by deducting the co-seismic displacements.The results reveal: 1) the effect of Kunlun Ms8.1 earthquake on the northeastern margin of Qinghai-Tibet plateau is obvious;2) the velocity field obtained with this method is better than the original GPS velocity field for reflecting the status of regional crustal movements and strain.
