摘要：通过对2009年、2011年和2013年通过CMONOC计划的三次活动观测到的约2000个GPS站点的数据分析，报道了中国大陆新的水平全球定位系统(GPS)速度场。假设地壳块体描述它们的运动学行为，利用GIMPSY软件对22个地壳块体的参数进行估计，以拟合GPS的速度。我们限制我们比较两个相互竞争的模型，在这两个模型中，涉及刚性块和变形块。我们的模拟表明，以相干运动和内部应变为特征的大多数地块可能更好地描述了中国大陆地壳形变的运动学。
Abstract: We report a new horizontal Global Positioning System velocity field in the Chinese mainland from the data analysis of about 2000 GPS sites observed in 2009, 2011 and 2013 through three campaigns of the CMONOC project. Assuming the crustal block to characterize their kinematic behaviors, we estimate parameters of 22 crustal blocks to fit the GPS-derived velocity by using GIPSY software. We restrict us to compare two competing models in which the rigid blocks and the deforming blocks are involved. Our modeling suggests that the most crustal blocks characterized by coherent movement and internal strain may be better in describing the kinematics of crustal deformation in the Chinese mainland.
