摘　　要：该文对地理边界进行了深入探讨,认为:1.地理边界是由划界因子确定的拓扑结构面,其空间关系根据地缘结构的时空耦合变化;2.地理边界划分依据地理隔离、区域均势、因子梯度而定;3.地理边界是地理现象整体发展中的“断片”,具有时空耦合的统一基础,4.统一地理边界是相互整合的有限划界因子集上的划分,是相对统一的。The paper focuses on geographic boundary and conclusions are drawn up: (1) geographic boundary is a topological surface which is demarcated by partitioned elements and varies with temporal and spatial coupling in boundary structure; (2) geographic boundary is delimited in terms of geographic isolation, regional potential and element gradient; (3) geographic boundary is a fraction of geographic phenomena in operation and it possess an integrated base with temporal and spatial coupling; and (4) the integrated geographic boundary is delimited according to integrated definite set of partitioned elements and is reiatively integrated.
