Abstract: GPS data from Shanxi Continuously Operating Reference Stations(CORS) during the period of 2009-05 and 2011-02 were processed using GAMIT/GLOBK software.Then coordinate time series and velocities of the reference stations were determined.Based on it,crustal movement of the Shanxi Province was analyzed in detail.Results show that the absolute horizontal velocity of the stations inside this region move at 33.97 mm·a-1 on average in the direction of SEE110.55° under the ITRF2005 reference frame,while the average horizontal velocity relative to the Eura-Plate is 6 mm·a-1 in the direction of SE130.69°.As for the vertical velocity field under the ITRF2005 frame,subsidence behavior is shown in most areas.Moreover,stations in the southern part subside at a higher rate than those in the north.Main cause of the subsidence is due to the long-term exploitation of groundwater and coal,which is much worse in the southern region.
