城市地铁交通网络可达性与社会经济关系分析

Urban Network Analysis in Beijing Based on Subway Accessibility

不同的路网结构对居民的便利性有不同的影响。城市地铁的建设和完善扩大了城市空间,为居民通勤提供了便利,同时,它也影响和改变着城市格局。本文以北京市为例,基于北京完备的地铁网络,采用空间句法对其现状和可达性进行评估。利用社会经济网络评价北京市各区的中心性指数,分析社会经济网络与各区可达性水平的联系。结果表明,北京的交通中心是西城区和东城区,而经济中心是海淀区和朝阳区。北京主城区呈现三核城市模式发展,预测未来发展方向将在石景山区和大兴区。

Different road network structure has a different impact on the convenience of residents.The construction and improvement of urban subway compress the city in space,provide convenience for residents commuting.At the same time,it also affects and change the city pattern.The experiment will be applied in Beijing,which improved the subway network at an early time.The status of urban subway network and the accessibility of it will be evaluated using space syntax method.Evaluate the centrality index of each district in Beijing by social and economic network,and analyze the connection between the social economic network with the level of accessibility of each district.The results showed the transportation center of Beijing is Xicheng and Dongcheng district.While the economic center is Haidian and Chaoyang district.The main districts of Beijing are developing with three-core urban model.The differences between the metro network and the economic network shows that Daxing and Shijingshan district could be the future development direction.
