交通优势度与人口流动的空间格局及互动关系研究——以山东省为例
A Study on the Spatial Pattern and Interactive Relationship between Traffic Advantage and Population Mobility—A Case Study of Shandong Province

交通建设和人口流动相互促进和制约，两者的协调均衡发展是实现以人为本的交通强国战略的切实保证。引用交通优势度模型、社会网络分析法和耦合协调度模型，对交通和人口流动两个系统的空间分布特征及相互作用关系进行量化分析。结果表明：山东省公路和铁路的交通优势度分别呈现中间高四周低的“核心–边缘”结构和单核心的“放射状”结构；山东省的人流网络密度整体较低，高密度区呈现核心阴影效应，联系强度的空间邻近性显著，城市个体的人口流动势能差异较大；交通系统对人口流动系统的带动和约束作用相对更强，根据发展水平组合关系可分为16类，以超前型和同步型为主，根据耦合系协调关系分可为3类，以公路、铁路均为良性协调的类型为主。
The traffic construction and population mobility promote and restrict each other. The coordinated and balanced development of the two is the practical guarantee for the realization of the people- oriented transportation power strategy. The traffic dominance model, social network analysis method and coupling coordination model are used to quantitatively analyze the spatial distribution characteristics and interaction between the traffic and population mobility systems. The results show that the transportation advantages of highways and railways in Shandong Province are “core edge” structure, which is high in the middle and low around, and “radial” structure, which is a single core. The density of people flow network in Shandong Province is low as a whole, the high-density area presents the core shadow effect, the spatial proximity of the connection intensity is significant, and the potential energy of population flow of urban individuals is different. The transportation system plays a relatively stronger role in driving and constraining the population mobility system. According to the level of development, the combination relationship can be divided into 16 categories, mainly advanced and synchronous. According to the coordination relationship of the coupling system, it can be divided into 3 categories, mainly highway and railway are benign coordination.
