No direct relationship has been demonstrated between the direction of relative plate motion and linear indicators of movement direction on shallowly dipping foliations, thrusts and faults.

Relative plate motion can not demonstrate the motion velocity of individual plate, while absolute plate motion can show the motion velocity in the stationary geospace.

The absolute plate motion model can be achieved by inverting the data set of the propagation rates and/or trends of volcanic chains to determine the origin in the angular space for the relative plate motion.

So the authors consider that the formation and evolution of the Chinese inland basins are the necessary result of plate movements since Paleozoic.

For this information, it can be induced that the rotative velocity of the liguid outer core presents similar nonuniformity, and the nonuniform rotation will have an effect on crust plate movement.

In order to surmount many deficiencies in determining the parameters of plate movement by least square(LS) method,we have set up a semiparametric model based on compensated LS principle.

This paper gives a background review of geodynamical researches on plate motion,introduces the internal wave hypothesis and latitudinal normal density hypothesis presented by Chinese scholars recently.

Under the deformation analysis model composed of rigid plate motion + uniform strain of the plate + inner non-homogeneous strain of the plate, the movement and deformation of each main plate of the globe have been studied based on the velocity field data announced by IERS in the frame of ITRF2000 at 657 GPS,SLR and VLBI stations distributed on main plates.

In this paper, a new present-day global plate motion ITRF2000VEL is determined on the basis of space geodetic data, incorporating the ITRF2000 velocity fi.
