The surrounding area of Ordos block located between Qinghai-Tibet block and north China block is one of the regions where the tectonic movement is most intensive in China mainland. Five large earthquakes with magnitudes greater than or equal to 8 have occurred in this region since 1300. In order to investigate the crustal movement, strain distribution and fault slip rates in this region, GPS data observed from 2009 to 2013 were collected at 527 campaign-mode and 32 continuously operating GPS stations and used to calculate a precise and high spatial resolution velocity field and strain rate field. The results reveal that GPS sites within Ordos block move towards NEE, the rates of these sites change little, and the strain rates are between (-1.0 similar to 1.0) X10(-8)/a. Tectonic movement and deformation of Shanxi rift is most intensive. The belt between Shanxi basin and its western mountains is under extension with a strain rate of (1.0 similar to 3.0)X 10(-8)/a. Meanwhile, the belt between Shanxi basin and its eastern mountains is under contraction with a strain rate of (2.0 similar to-3. 0) X 10(-8)/a. The faults at the west boundary of Shanxi basin show 2 similar to 3 mm . a(-1) of normal-fault extension. However, the faults at the east boundary of the basin demonstrate right-lateral slip rates of 1 similar to 2 mm . a(-1) and contraction rates of 1 similar to 3 mm . a(-1). The Linghe depression in the west of Hetao rift shows significant extensional deformation with a strain rate of (2.0 similar to 3.0) X 10(-8)/a. There is a shortening motion of 2.1 mm . a(-1) in the southwest of Ordos block, while the velocity rates change little near Liupanshan fault system. It reveals that the fault system is locked in deep. Weihe fault system shows 1.0 mm . a(-1) of left-lateral slip. Weihe basin is experiencing weak extensional deformation.
