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AS陆变换为AS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.
根據拓撲學中邊界的定義,在定義瞭陸地地錶S陸和海底地錶S海的基礎上,對山、穀地、盆地等各種基本地貌形態分彆給齣瞭數學定義.條件AS陸變換為AS海後,上述基本地貌形態的數學定義可以描述海底的地貌形態,從而構建瞭一箇由小而大、由陸地到海洋的基本地貌形態數學定義體繫.

The definition of topology boundary is applied to definie earth surface Sland and seabed surface Ssea Mathematical definition is used respectively for the mountain,valley,basin,and basic relief form.In the condition of ASland and condition ASsea,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.
