基于拓扑网络的江淮城市群通达性分析

Analysis about Jianghuai Urban Agglomeration of the Accessibility Based on Topological Network

江淮城市群是安徽省域经济发展重点区域,通达性是衡量城市群内在联系的重要指标。文章基于江淮城市群境内高等级公路拓扑网络图,对该区域的通达性特征进行分析。结果表明:江淮城市群整体通达性水平良好,各城市间通达程度存在明显差异,天然地理障碍对城市通达性的影响较为明显。

Jianghuai Urban Agglomeration is the key area of economic development about Anhui province. While accessibility is an im- portant index which measures the linked function of the Urban Agglomeration. This paper draws the access features of the Cities through the topological network analysis of the high-class way. The results shows that Jianghuai Urban Agglomeration has a good level of the overall acces- sibility, there are significant differences between different cities, the natural geographical barriers are the more obvious influence on the ac- cessibility of the cities.
