联合GPS基准站和验潮站数据确定海平面绝对变化

Determination of the Absolute Rate of Sea Level by UsingGPS Reference Station and Tide Gauge Data

摘要: 采用中国地壳运动观测网络工程厦门基准站的GPS观测数据以及厦门验潮站的验潮数据,计算了厦门海域的海平面绝对变化速度,并就高程变化问题作了深入讨论,表明点位高程变化呈周期性,几期GPS连续观测受其影响不能得出实际的高程线性变化速率,指出了要监测验潮站的地壳垂直运动,最好采用多年连续的GPS观测数据。

Abstract: The rate of absolute mean sea level of Xiamen sea area is derived from the data of Xiamen tide gauge station and Xiamen GPS fiducial station of crustal movement observation network of China. The height variety is discussed in this paper. It is shown that height has spread and periodic variations. So the precision rate of vertical land movement can not be obtained only from several GPS campaigns.
