摘要:

村落空间网络是以农村居民点为节点、线性设施为依托、节点相互作用而构成的复杂网络。开展村落空间网络及其节点中心性研究能够理清节点在网络中的关键位置与影响范围,为农村居民点规划建设、整体网络结构优化提供理论借鉴。本文以重庆市江津区燕坝村为例,运用复杂网络理论与方法构建村落空间网络,进而辨析网络中心点及其辐射强度与辐射范围,厘定出农村居民点体系优化重组模式。结果表明:① 村落空间网络具有典型的非均衡层次结构、小世界特征与无标度特性,网络整体的联系程度较低;② 依据中心点的辐射能力划分其等级,形成Ⅰ级中心点、Ⅱ级中心点和Ⅲ级节点共同作用的网络节点体系;③ 基于此,从“整体-局部-个体”3个影响层次,构建了中心村(Ⅰ级中心点)扩散型、基层村(Ⅱ级中心点)增长型、散居农村居民点(Ⅲ级节点)挖潜型3类优化重组模式。

Abstract:

Rural spatial networks are complex networks consisting of rural settlements and linear facilities. They take rural settlements as nodes and linear facilities as the support; nodes interact within it. Rural spatial networks and node centrality are capable of identifying the key position and influence of nodes in the network, providing a theoretical reference for planning and construction of rural settlements and overall network structure optimization. Taking Yanba Village of Jiangjin district in Chongqing, we established a household and rural settlements database with spatial data links to attribute data by adopting the 3S+PRA method. We measured comprehensive quality and accessibility of rural settlements by comprehensive evaluation and grid analysis methods to determine the connection degree among rural settlements by improved potential models. Using the rural settlements in the village as nodes and the connection degree among rural residential areas are edges, we constructed a village spatial network using complex network theory to identify network center points, radiation intensity and radiation range. The results show that the village spatial network has a typical non-equilibrium hierarchical structure, small world characteristics and scale-free characteristics, and low overall connectivity. According to the radiation of the center points, a network node system consists of I, II and III center node interactions as classified. On this basis, three levels of influence from the whole to parts and individuals and three optimization and recombination patterns are constructed. These include the central village (grade I center) diffusion type, grassroots village (II Center) growth type, and scattered rural settlements (grade III node) promising type.
