本文采用几何水准、海洋水准和卫星测高的综合法求得了较准确的中国近海海面地形，详细分析了中国近海海面地形的机制。经比较，海洋水文法（不考虑气压改正，认为海水温度、盐度是影响海面地形的主要因素）在黄渤海及东海海区的计算结果与综合法很接近，但在华南沿海约有２１ｃｍ的系统性差。经进一步研究发现，这是由于华南沿海（厦门至八所）气压影响造成的，气压的均衡效应、气压的非均衡效应、气压扰动和海平面波动的共振使海平面显著升高。此外还发现，太平洋北赤道流对东山至遮浪海区的海平面高度的机制也有影响。最后研究了海平面高度与纬度的关系，得出了一些有价值的结论。
In this paper, the more accurate sea surface topography of China’s coastal area is obtained by the method of geometric level, ocean level and satellite altimetry. The mechanism of sea surface topography in China’s coastal area is analyzed in detail. By comparison, the results of ocean hydrological method (without correction of atmospheric pressure, sea temperature and salinity are the main factors influencing sea surface topography) are close to the comprehensive method in Huang-Bohai Sea and East China Sea. However, Poor sex. After further study, it was found that the sea level was significantly increased due to the pressure effects of the coastal areas of South China (eight to eight in Xiamen), the equilibrium effect of air pressure, the non-equilibrium effect of air pressure, the pressure disturbance and the resonance of sea level fluctuations. In addition, it was found that the mechanism by which the equatorial Pacific equatorial Pacific flows to the sea level from Dongshan to the covered area also has an impact. Finally, the relationship between sea level and latitude is studied, and some valuable conclusions are drawn.
