摘要
本文介绍了海面地形的概念和测量方法,采用Engelis的海面地形数学模型计算出中国近海海面地形,比较了海面地形差距与验潮站平均海面的几何水准差距是一致的,得出了青岛站高程起算面高于世界大洋海面地形为零的大地水准面约0.25m。本文对研究中国近海平均海面、海面地形和海洋大地水准面都有一定的理论意义和参考价值。
This paper offers an introduction to the concept of Sea-Surface Topography and the survey methods related. Engelis' mathematical model is used in obtaining China Offshore Sea-Surface Topography. Sea-surface topography difference is compared with that of geodetic sea level at the tidal stations and a consistency has been found which reveals that the elevation datum at Qingdao Station is 0.25 higher than the geoid of the global ocean surface topography which is zero.
