| 摘 要： | 介绍了求得中国近海海面地形的几何水准法、球函数模型法、海洋水准法,重点介绍了海洋水准法,并指出用水文资料计算中国近海海面地形时,必须考虑气压的均衡效应和气压的非均衡效应。定量分析了水文因素的影响,气压因素的影响,及太平洋北赤道流(黑潮)对中国近海海面地形的影响,得出了一些有益的结论。

| Abstract: | In this paper,the methods of geometric leveling,spheric harmonic function and hydrostatic leveling used for calculating the mechanism of off-shore sea surface topography are presented,where the hydrostatic leveling method is mainly mentioned.The paper also pointed out that the isostatic effect and non-isostatic effect of atmospheric pressure must be considered when the Chinese off-shore sea surface topography is computed by using the hydrologic data.With the quantitative analysis of the effects on Chinese off-shore sea surface topography caused by the factors of hydrology and atmospheric pressure,and the north equatorial current(Kuroshio)in pacific ocean as well,some useful conclusions have been obtained. |
