摘要: 摘  要:城市群交通网络的合理发展对于促进区域资源整合与协调发展具有重要意义。采用空间句法模型,分析1995~2015年中原城市群交通网络通达性演化特征,并提出相应交通网络优化改进建议。结果表明:(1)1995~2015年期间,中原城市群交通路网由初期的“发散”状,逐渐演化成为“树轮”状;通达性中心也由初期的郑州市扩大到洛阳市、许昌市、周口市、商丘市、开封市等周边城市,通达性较高的轴线已经从区域性线状分布发展为中心地区面状分布。(2)1995~2015年期间,中原城市群各城市通达度均有提高,京广线辐射区内城市通达度提升幅度明显大于陇海线辐射区域;郑州市、邯郸市等核心城市的通达度增长率在减缓,而亳州市、淮北市等边缘城市通达度增长率在上升。中原城市群交通路网建设总体呈空间收敛趋势,但城市间的通达度水平仍在逐渐拉大。(3)基于以上分析,研究提出将中原城市群交通系统整体培育成以郑州市为中心,以陇海线和京广线为“十”字发展轴的“多核多向状”网络结构。改进后的路网可以提升中原城市群各城市的通达性,能够充分体现城市群中心带动边缘、城市联动发展的基本功能。

Abstract: Abstract:The rational development of urban agglomeration transportation network is of great significance to promote the integration and coordinated development of regional resources. Based on the spatial syntax model, this paper analyses the evolution characteristics of traffic network accessibility in the Central Plains urban agglomeration from 1995 to 2015, and puts forward corresponding suggestions for traffic network optimization and improvement. The results show that: (1) From 1995 to 2015, the traffic network of the Central Plains Urban Agglomeration has evolved from the initial “divergent” shape to the “tree-ring” shape, and the accessibility center has expanded from Zhengzhou in the initial stage to Luoyang, Xuchang, Zhoukou, Shangqiu, Kaifeng and other surrounding cities. The axes with higher accessibility have developed from the regional linear distribution to the central area. (2) From 1995 to 2015, the accessibility of all cities in the Central Plains Urban Agglomeration has increased, and the increase of accessibility in Beijing-Guangzhou Radiation Area is significantly greater than that in Longhai Radiation Area; the growth rate of accessibility in core cities such as Zhengzhou City and Handan City is slowing down, while the growth rate of accessibility in border cities such as Bozhou City and Huaibei City is rising. The traffic network construction of Central Plains urban agglomeration shows a trend of spatial convergence, but the level of inter-city accessibility is still increasing. (3) Based on the above analysis, this paper proposes to cultivate the transportation system of the Central Plains Urban Agglomeration as a whole into a “multi-core and multi-directional” network structure with Zhengzhou as the center and Longhai and Beijing-Guangzhou lines as the “ten” development axes. The improved road network can improve the accessibility of the cities in the Central Plains urban agglomeration, and fully reflect the basic functions of the urban agglomeration center to drive the marginal and urban linkage development.
