在江苏省高速公路网络2012年12月OD流量数据和通行时间数据支撑下,本文从县市尺度出发,在对城市空间关联的节点、路径和组团等要素分析基础上,尝试勾绘关联特征的基本图示。结论如下:1城市节点分布有一定的等级性,且节点重要性本身与其社会经济发展状况或在高速公路的功能定位有关。2单一组团或近邻组团以“中心城市+关联节点”进行关联,且城市间的通行时间基本在1小时内,而中长距离的双核心或多核心的组团则以中心城市作为联系基轴建构,且通行时间在1—3小时之间。3综合节点、路径和组团等要素勾绘的城市关联特征模式包含苏北系统、跨江系统和苏南系统,且该模式昭示以“多板块协同发展”的思路规划区域发展战略可作为优先考虑的方案。
Based on the data of the OD traffic data and the transit time data of expressway network of Jiangsu Province in December 2012, this paper starts from the scale of cities and counties, and based on the analysis of the elements, such as the nodes, paths and groups associated with the urban space, Basic illustration. The conclusions are as follows: 1 The distribution of urban nodes has a certain degree of hierarchy, and the node importance itself is related to its social and economic development or the functional orientation of the expressway. 2 A single group or a neighboring group is associated with “central city + associated node ”, and the passage time between cities is basically within 1 hour, while the long-distance dual-core or multi-core group uses the central city as the connection base Shaft construction, and the passage of time between 1-3 hours. The pattern of city association characterized by elements, such as comprehensive node, path and grouping, includes the North Jiangsu system, the inter-river system and the southern Jiangsu system, and the model shows that planning the regional development strategy with the idea of “multi-plate synergy development” Priority program.
