| 摘 要： | 采用块体运动的整体旋转与线性应变模型(RELSM)描述块体内部形变,利用具有高崩溃污染率的抗差估计方法,对中国大陆构造环境监测网络在环渤海区域的GPS观测速度场数据进行测站筛选及拟合分析。结果表明,本文方法不仅能较好地兼顾块体整体运动的平滑性和局部构造运动的差异性,还能抑制粗差的影响,可获得较好的速度场拟合结果。

| Abstract: | Abstract: In this paper, we use the equation of rotation in the entire block and the linear strain model(RELSM) of block motion to describe the internal deformation of the block. We use the robust estimation method with high breakdown point to screen abnormal stations. The station screening and fitting analysis of the velocity field data of GPS observations from crustal movement observation network of China in Bohai rim region are discussed. The result shows that the method can better balance the smoothness of the overall motion of the block and differences in local tectonic movements. Moreover, it can also suppress the influence of gross error, so as to obtain a better velocity field fitting result. |
