Deep dynamic mechanism of the Tienshan region is a hot spot in geodynamics research,and seismic anisotropy is an important feature of the deep dynamic mechanism of the regional structure. The results show that the crust anisotropy of the Tienshan region is regional and affected by tectonic belt,fault strikes and regional stress. The upper mantle anisotropy shows that the fast polarization direction is generally parallel to the strike of the Tienshan tectonic belt,but becomes complex near the Issyk-Kul Lake,Tarim Basin and Junggar Basin,and regional double-layer anisotropy phenomenon exist in local area. The complex vertical variation may be due to the regional double layer anisotropy,but also needs further study to prove. Many researches about the crust and mantle of the Tienshan region support vertical coherent deformation mechanism. In addition,the mantle plume,asthenosphere deformation and small-scale mantle convection are all used to explain the dynamic mechanisms in the Tienshan area,which indicate the deep dynamic mechanism needs further research.
