摘要
根据拓扑学中边界的定义,在定义了陆地地表S陆和海底地表S海的基础上,对山、谷地、盆地等各种基本地貌形态分别给出了数学定义。条件A S陆变换为A S海后,上述基本地貌形态的数学定义可以描述海底的地貌形态,从而构建了一个由小而大、由陆地到海洋的基本地貌形态数学定义体系。
The definition of topology boundary is applied to definie earth surface S land and seabed surface S sea Mathematical definition is used respectively for the mountain, valley, basin, and basic relief form. In the condition of A Sland and condition A S sea the mathematical definitions of basic relief form may describe the relief form of seabed surface. Mathematical definition system of basic relief form is put forward from earth surface to seabed surface.
