摘要
用几何水准法、水文法、重力—卫星测高法三种不同方法求得了中国近海海面地形,给出了中国近海海面地形数学模型和中国近海海面地形图,探讨了中国近海海面地形形成机制,包括海洋水文因素、大气压力影响,以及太平洋北赤道流的影响。
This paper uses the geometric leveling method, the hydrographic method and the gravity-satellite altimetry method to gain the inshore sea surface topography of China, and gives out the mathematic models and the sea surface topographic map of Chinese inshore, then discusses the sea surface topography mechanism of Chinese inshore, include the marine hydrographic factors, atmosphere pressure effects and the North Equatorial Current of Pacific Ocean effects.
