Abstract: China Geodetic Coordinate System 2000(CGCS2000)is national new geocentric coordinatesystem of China,it has been adopted nearly 7years since July 1,2008,and it is being applied fully indifferent fields.The progress made in the construction CGCS2000framework was reviewed in this pa-per,the refinement of CGCS2000framework was introduced,and especially the plate motion modeland grid velocity field model which modeled in the CGCS2000frame maintaining were focused on de-scription,the update recommendation about CGCS2000frame was given at the end of this paper.
