///Assuming that the GPS velocity field is greatly affected by the interseismic elastic deformation of the upper crust, under the constraints of the existing GPS data, and referring to the elevation data and the NUVEL-1A model of global plate movement, the authors constructed the viscoelastic mechanical models to analyze the rationality of the explanation to the Tibetan present-day crustal movement by two different deformation mechanisms in the deep continental lithosphere, including the viscous flow in the lower crust and the ductile strain localization in the deep fault zones. Numerical experiments show that the present-day crustal movement in different regions of the oft-com:office:smarttags" />Tibet may be attributed to different geodynamic mechanisms. Due to the high elevation and the lower viscosity of the lower crust, the gravity plays an important role in the present-day movement of the Tibetan Plateau.oft-com:office:office" />
