介绍了海面地形的研究现状,并根据几何水准求得了中国近海的海平面倾斜及其精度.给出应用水文资料计算中国近海海面地形的公式及其计算结果。探讨了由球函数模型计算中国近海海面地形的理论和方法,并对不同方法进行了比较,得出了一些有益的结论.
The present research status of sea topography is introduced and the sea level tilt and its accuracy in offshore China are obtained according to the geometric level.The formula to calculate the sea surface topography of China offshore by using hydrological data and its calculation results are given. The theory and method of calculating the sea surface topography of China’s offshore by the spherical function model are discussed. The different methods are compared and some useful conclusions are drawn.
