【摘要】 城镇区域网络空间结构是由城镇间的联系网络构成的空间等级结构,是交通网络、经济网络、信息网络相互叠加、复合形成的结果。本研究的目的在于分析不同时段各城镇节点在诸联系网络中所处的地位及彼此间的联系程度,以此判断整个城镇形成的空间网络形态和演化过程所呈现的规律,希望本研究结果能对各城镇未来的发展方向提供理论决策。本文以银川平原城镇区域为研究对象,归纳总结了近年来学者对城镇网络、区域空间网络的研究成果,对城镇区域网络空间结构、信息网络和城镇复合网络的概念进行了界定；借鉴网络城市、流动空间、复杂网络理论分析了研究区域网络空间结构的形成、演变过程及演化特征。首先,将银川平原不同时段的交通图进行拓扑变换,选取通达性、关联度、中心性等指标分析交通网络的演化过程、规律与影响因素,得出不同时段银川平原的空间结构呈现的特征。其次,构建城镇间经济联系模型,为不同时段的城镇进行等级划分,确定各城镇间的联系方向,以此来分析经济流的空间涨落过程,同时探讨了银川市经济中心与门户城市的重叠效应。再次,从理论上分析了信息网络如何促进城镇区域从层级结构向网络结构演进,建立区域信息化空间差异测评体系,运用层次分析法对不同时段的城镇进行了信息化水平的测度,并对其进行了信息化空间差异的分类,以此探讨各城镇间信息化空间差异的发展趋势。最后,通过对复合网络协调度的计算,得出不同时段银川平原复合网络的空间结构,探讨了优化策略。研究结果表明,银川平原的空间结构从单中心的中心地模式向多中心的网络化模式转变；发展过程中银川市一直是核心城市；网络结构中,只有少数的城镇节点有大量的网络连接；城镇节点偏向于就近连接；城镇间的网络联系渐趋复杂化；吴忠的亚核心地位开始凸显。更多还原

【Abstract】 Network space structure of urban area is the space level structure composed of associative network between different cities. It is the result of traffic network, economic network, and information network stack with each other. The purpose of this paper is to analyse the position which is the urban in the relation network and the relationship between each other in different periods, to judge the space network morphology of the whole town and the law which presented in the evolution process. I hope the result of this study can provide a theoretical decision for the urban’s development direction in the future.Based on the urban in the yinchuan plain area as the research object, this paper summarizes the research results of the urban network and regional spatial network in recent years,with defines the urban regional spatial network, information network and the urban complex network. Referencing network cities, flow space and the complex network theory,the paper analyzes the formation, the evolution process and evolution characteristics of network space structure in research area.First of all,this paper takes topological transformation among different traffic map in Yinchuan plain, selecs the accessibility, correlation degree and the centricity index to analysis evolution process, rules and influence factors of the traffic network.It is to get a different period of yinchuan plain space structure characteristics of the present. Secondly, through the construction of economic relation model,the paper divides the urban classes of different times, determines the relationship between direction of each town, in order to analysis the flow of economic fluctuation space process, discusses the economic center and yinchuan gateway city of overlap effect. Again,the paper analysis the process of the information network to promote urban area from level structure to the network structure evolution theoretically, through the establishment of regional informatization spatial difference evaluation system, the paper measures the informatization level of urbans of different periods using the analytic hierarchy process. It analyses the classification of information space difference, and discusses the information space of the differences between urban development trend. Finally, based on the calculation of complex network coordination degree, the paper gets the result of space structure of the complex network in the yinchuan plain in different period and discusses the optimization strategy.The results show that, the spatial structure of Yinchuan plain has a change from the single center mode of center to multiple centers network mode. In the process of the development, Yinchuan has been a core city. In network structure, only a few towns node has a large number of network connections; towns node is biased in favor of the nearest connection:the network connection between town gradually complicated; the core position of Wuzhong will be highlighted.更多还原
