中文摘要：

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。

英文摘要：

Complexity is a measure of the level of organization of the system, when the system is compelled to be far away from the thermal equilibrium condition and enters the ordered state through self- organization, the complex structure appears frequently. As a typical, open and complex giant system, the transport network com- plexity research received a strong attention of various research areas. At present, the complex research of trans- port network mainly centralized in road network complex elementary theory （research direction and system）, the topology of road network （scaling, small-world, reliability and centricity） as well as the kinetics process of road network. However, few efforts have been devoted to the complexity emergence of road network from dy- namic process. Therefore, based on the urban-rural road network spatial databases of Wuhan urban agglomera- tion ,this article systematically reveals the topological structure evolution and complexity emergence of ur- ban-rural road network with the application of complex network theory. Urban-rural road network is a typical two-dimensional plane picture, lacking of ＂super planarity＂, and overall showing a similar characteristic of sto- chastic network. Urban-rural road network is a complex network which evolves between random network and regular network so that the whole road network demonstrates a performance of cross-coupling of the random- ness and orderliness. Complexity evolution of urban-rural road network system is the result of the joint action of self-organization and hetero-organization mechanism, and the complexity emergence of urban-rural road net- work is a mutually alternate and ever-changing process in the function intensity, which was mainly influenced by the partial random disturbance and regularity regulation. Transportation network is the material conditions and prerequisites for forming the metropolitan area network system. It is also the main channel of material flow, energy flow and information flow which play important role in
