The unusual reactivation of the North China Craton(NCC)challenges the classical theories concerning the strength and stability of cratonic lithosphere and plays important roles for improving our understanding of the plate tectonics. The origin of seismic anisotropy is of fundamental importance to the understanding of the lattice?preferred orientation(LPO)of mantle minerals and mantle flow that produces it. The LPO of anisotropic olivine crystals in the upper mantle is believed to be the primary cause for SKS wave splitting，and the measurement of seismic anisotropy can provide key clues to distinguish deformation pattern of the upper mantle. In this paper, 493 shear wave splitting results in the North China Craton by using SKS phase，which are from 138 stations covering the NCC with dense spacing，are summarized. The strong anisotropy，rapid variation of splitting parameters imply that the shear wave splitting is mainly caused by the upper mantle anisotropy and reflects the effects of tectonic controls. We suggest that the Ordos block possibly remains the weak anisotropy of the Precambrian craton similar to that of the Kaapvaal Craton，south Africa，Proterozoic amalgamation generated the seismic anisotropy in the boundary zone between the Ordos Block and the Trans?North China Orogen，while the anisotropy in the eastern Trans?North China Orogen and eastern NCC were possibly associated with the lithospheric rejuvenation during the Late Mesozoic to Cenozoic.
