Abstract: In this paper, The author firstly introduced the processing strategy of obtaining the coordinate and velocity base on the CGCS2000(Chinese geocentric 3D coordinate system), Secondly a new plates displacement reference frame of Chinese mainland subjected to the regional No-Net-Rotation (NNR) conditions is researched,The results inferred the position of the Euler rotation pole of the Chinese mainland plates is (64.77°N,94.093°E) and its rate is 0.2997(°)/Ma base on the CGCS2000. Finally, Crustal movement velocity field of Chinese mainland are inferred through the precise result of CORS and national GPS network, and the model of crustal deformation velocity field has been established base on the adoptions of Finite Element Interpolation method. On which, the regional crustal deformation characters of china mainland have been proximately analyzed. Base on the study of this paper, the precision, dynamic and reliability of CGCS2000 would be further renewed and maintained, further more the basic data with high spatial-temporal resolution and scientific methods are referred to study characteristics of Chinese mainland crustal movement.
