中国大陆现时地壳水平运动特征及其驱动机制

摘要

利用1999-2007年中国大陆及邻区在ITRF2007参考框架下的1 068个GPS观测成果,以地统计分析为基础,应用运动学研究方法,分析了中国大陆及邻区地壳表层速度场的分布特征,以及印度、欧亚、菲律宾、太平洋4大板块在相互作用过程中,对中国大陆及其邻区地壳表层运动与变形分布的影响范围和程度以及驱动机制进行了分析.%In the work, on the basis of geo-statistics analysis, with the kinematics method and by use of the 1 068 results of GPS observation in the China continent and its adjacent under the ITRF2007 reference fromwork the distribution characteristics of the horizontal crustal velocity field and the driving mechanism are studied. The influence range and degree of relative action between the India, Eurosia, Philippines and Pacific Ocean Plates on the movement and deformation of the China continent and its adjacent region are analyzed as well.
