摘　　要：针对现有速度场模型采用数据少、现势性不强的问题,详细论述了速度场模型建立的数据获取与处理方法,利用中国大陆地壳运动监测网络中260个连续运行基准站2011~2015年的连续观测数据,采用GAMIT/GLOBK与GMT软件,获得高精度的定位及速度成果,并基于上述速度成果采用克里金插值法构建了中国大陆地壳运动速度场1°×1°格网模型。最后利用IERS公布的中国区域7个IGS站实测速度以及全国范围内均匀分布的陆态网络区域站实测速度,对模型内插结果进行检核,验证了模型的现势性、精确性和可靠性。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 ve- locity of the 260 stations have been calculated with GAMIT/GLOBK and GMT software. Building the 1°X 1° grid model of velocity field in China's Mainland 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.
