摘要: 根据中国地壳运动观测网络基准网1998年9月初至2002年6月底GPS连续观测结果,结合各基准站的水平位移的分量时间序列,试图利用空间上更直观、更清晰的水平位移向量方法进一步说明中国地壳运动观测网络基准网水平位移测量精度、水平方向点位稳定性及2001年11月14日昆仑山口西8.1级大地震前后的地壳水平运动时空演化过程。

Abstract: Based on the results of GPScontinuous observations at the fiducial stations in theCrustal Movement Observation Network of China(CMONOC) from early September 1998 tothe end of June 2002 and combined with the time series of the displacement components aeach station, the authors have tried to discuss in a conceptually direct and clear way on the ac-curacy of the horizontal crustal movements, the stability in the horizontal position of the monu-ments of the fiducial stations in CM(DNOC and the temporal and spatial evolution of the hori-zontal crustal movements before and after the great Kunlun mountain earthquake with M8. 1on Nov. 14, 2001.

Key words: Crustal movement, GPS, Time series, Great Kunlun mountain earthquake with M8.1, Displacement vector
