摘　　要：信息流动空间的支配性功能实质性地改变了现代城乡文化的空间结构。基于文化信息流的表征,通过构建武汉城市圈城乡文化节点的结节性测度指标体系,运用建模将文化节点的影响范围转化成结节性指数、文化节点等级与文化传播方式相结合的函数,发现信息化背景下武汉城市圈城乡文化的空间结构有三个特征:1城乡文化节点呈现以"京广"铁路为界东高西低的等级体系,其功能趋于软化;2文化廊道日益凸显,城乡文化空间结构的弹性逐渐增强;3城乡文化空间结构趋于网络化。信息化背景下应充分利用市场配置规律,发挥文化廊道的正效应,构建公共文化设施网络,优化文化信息流动空间,重塑现代城乡文化的空间结构。The spatial structure of urban-rural cultures includes that the cultural elements own their relative lo- cation and relationship, their interaction, mutual adaptation, the degree of agglomeration, and relative equilib- rium relation between urban and rural areas in space. First and foremost, following the generalization that cultural information usually flows from the higher-grade nodes to lower-grade ones and the basic theoretical orientation of modern cultural communication, we manage to construct the tuberous measure index system for urban-rural cultural nodes in Wuhan city circle according to the representation of cultural information flow. Finally the tuberosity of the cultural nodes based on the spatial buffer and spline curve is analyzed with ArcGIS. From the view of point, line and surface, the paper demonstrates the evolution of the spatial struc- ture of urban-rural cultures in Wuhan city circle under the information background. Three characteristics and regular findings are as follows： （1） there is hierarchical system with four grades in the urban-rural cultural nodes, which represents that the first-grade and the second-grade cultural nodes generally distributes spatial- ly like a cross-shaped pattern along the Beijing-Guangzhou Railway and Yangtze River Economic Zones, while the third-grade and the fourth-grade ones are located in the quadrants of the cross-shaped pattern; （2） the outline of the cultural corridors is increasingly apparent; （3） the spatial structure of urban-rural cultures presents the tendency of network, while the signs of cultural agglomeration start to appear.
