Abstract With the fast rise in the number of GPS continuous operational reference system (CORS) stations in China, and geodesy and geodynamics subjects growing on the basis of geographic information needs, it is imperative to establish a high precision velocity model in China. China’s mainland is divided into five blocks: Northeast China, North China, South China, Qingzang (Tibet) and Northwest China.The study is performed on construction of the velocity field model in China’s mainland on the basis of three methods: Kriging interpolation, higher collocation precision in the blocks of Qingzang and North China, and the performance of the movable least squares collocation method.The latter is worse than other methods in all blocks.Finally, we apply configuration using Kriging interpolation and least squares collocation to estimate the 1°×1° center of grid velocity results.The resulting difference of the two methods is small.
