Abstract:Aim at the problem of fewness data and update slowly in velocity field, this paper studied the methods of data obtain and analysis for velocity field build. Using observation data from crustal movement observation network of China surveyed in 2011-2015. Both high precise coordinate and velocity of the 260 stations have been calculated with GAMIT/GLOBK and GMT software. Building the 1°×1° grid model of velocity field in mainland China using Kringing method based on the 260 stations velocity. And then estimating the grid model using the velocity of seven IGS stations in China from IERS and 2000 region stations from CMONOC. The result can be concluded that this grid model have higher pricese and reliability. The result in this paper have a great significant for engineering.
