摘要:

镇村社区空间网络是以镇区为依托、镇村社区为节点、彼此关联为连边构成的空间组织形态,探索其结构特征及其优化策略对引导要素合理流动、提升网络运行效率等具有重要意义。本文选取重庆市沙坪坝区凤凰镇19个镇村社区作为网络节点,采用修正后的引力强度模型反映节点之间的联系,运用GIS工具和社会网络分析法、相关性分析等方法探究镇村社区空间网络结构的总体特征、节点特征及差异特征,提出镇村社区空间网络的优化策略。研究表明:镇村社区空间网络总体处于低水平、非均衡的发展阶段,网络兼具整体松散性与局部集聚性,且小世界特征较为显著,凝聚子群之间的关联性差异明显;镇村社区空间网络呈现“核心-边缘”的节点结构,核心节点的结构洞优势有待加强;社区居民不同的社会属性对网络结构造成了差异性影响;基于此,拟从节点自身功能完善、节点等级体系构建及节点间经济联系强化等方面,构建“1轴、1心、18点”+“1网、57线”的空间网络化模式,为当前及未来的农村社区建设提供示范。

Abstract:

Spatial network of village and town communities is a spatial organization form that relies on the town and takes the village and town communities as nodes and connections between nodes as edges. Exploring its structural characteristics and optimization strategies is of great significance for guiding the sound flow of factors and improving network operation efficiency. By selecting 19 village and town communities in Fenghuang Town of Shapingba District, Chongqing Municipality as network nodes, this study applied the modified gravitational intensity model to explore the connections between these nodes. Using GIS tools, social network analysis method, and correlation analysis method, this study examined the general characteristics, node characteristics, and characteristics of difference of the spatial network structure of the village and town communities, and established the network optimization strategies. The results show that the spatial network of the village and town communities is in a low level, unbalanced stage of development, which possess characters of both general looseness and local agglomeration, the small world characteristic, and the association difference between cohesive subgroups is significant. The spatial network of the village and town communities exhibited a 3-level node structure that takes the town community as the core, community 5, 7, 4, 10, and 14 as secondary cores, and contains the other communities, among which the structural hole advantage of the core nodes needs further enhancing. Various social attributes of community residents cause different effects to the network structure. On these bases, this study constructed a "one axis, one core, eighteen nodes, one network, and fifty-seven links" spatial network pattern by improving functions of the nodes, building the node hierarchy, and strengthening economic relations among nodes, and therefore providing a demonstration for current and future rural community construction.
