摘要

摘要: 以12个GPS站12年的坐标序列为研究对象.采用Kashyap信息准则（KIC）噪声模型估计准则对四种组合噪声特性进行估计,探讨慢滑移（ETS）现象对GPS站坐标时间序列的影响,结果表明:ETS引起了GPS站坐标序列模型的变化,E、N方向分量噪声模型占比与U分量模型占比差异较大,可能造成噪声模型的错误估计;ETS后的站速度及其不确定度相比ETS前站速度及其不确定度均有增加,且在U分量表现明显;特殊地理位置的测站可进行标记研究,尽量减少地震运动带来的不利影响,为地壳运动研究提供有价值的参考资料．

Abstract: The 12-year coordinate sequence of 12 GPS stations is studied. The estimation criterion of KIC noise model is used to estimate the four combined noise characteristics, and the influence of slow slip phenomenon on GPS station coordinate time series is discussed. The results show that ETS causes the change of GPS station coordinate sequence model, and the ratios of E, N direction component noise model and U component model are quite different, which may cause erroneous estimation of noise model; the speed of the station and its uncertainty after slow slip are larger than before slow slip; and obvious for the U component. The station at special geographical location can carry out the marking research to minimize the adverse effects caused by the earthquake movement, and study the crustal movement, whih can provide valuable reference materials.
