【摘要】:复杂性是一个系统的自组织水平的度量,当系统被迫远离热平衡状态并通过自组织进入有序状态的时候,复杂性结构常常涌现。作为典型、开放和复杂的巨系统,交通网络复杂性研究受到了各研究领域的强烈关注。以1989~2010年武汉城市圈城乡道路网空间数据库为基础,运用复杂网络理论,多度量系统揭示了城乡道路网拓扑结构演化及复杂性"涌现"过程:城乡道路网是一典型的二维平面图,缺乏"超平面性",整体呈类随机网络性质;城乡道路网是一介于随机网络和规则网络间的复杂网络,道路网整体表现出随机性和有序性的交互耦合;城乡道路网系统的复杂性演化是自组织和他组织机制共同作用的结果,是局部随机性干扰和规则性调控在作用强度上相互交互、此消彼涨演替的过程。
[Abstract]:Complexity is a measure of self-organization level of a system. Complexity structures often emerge when the system is forced to move away from the thermal equilibrium state and enter an ordered state through self-organization. As a typical, open and complex giant system, the research of traffic network complexity has been paid close attention to. Based on the spatial database of urban and rural road network in Wuhan urban circle from 1989 to 2010, using the complex network theory, this paper reveals the evolution and complexity of urban and rural road network topological structure evolution and complexity "emergence" process: urban and rural road network is a typical two-dimensional plane map. Lack of "hyperplanarity", the whole is like random network property; Urban and rural road network is a complex network between random network and regular network. The complex evolution of urban and rural road network system is the result of the interaction of self-organization and other organization mechanism, and the interaction of local random interference and regular regulation in the action intensity.
