【摘要】：基于改进的引力模型,以湖北省浠水县散花镇为研究对象,分析散花镇43个行政村的空间相互作用格局,依据村镇网络的潜力指数和节点度定量化划分村镇等级体系,探讨其发展策略。结果表明,散花镇形成西南区域、省道S201沿线和东部区域3个显著分异的区域。西南区域行政村综合实力为71.92、可达性为19.39 min,优于镇域均值,其潜力指数和节点度多为I等,村村联系紧密,是村镇网络的中心;省道S201沿线行政村综合实力为66.44,潜力指数略低,为II等,但受益于良好的交通区位,可达性为19.20 min、节点度多为I等,村村联系广泛;东部区域实力弱,行政村综合实力为54.06,交通落后,可达性仅为27.23 min,潜力指数和节点度多为III等,村村联系松散,处于村镇网络的边缘。据此,根据潜力指数和节点度并从村镇网络结构与功能优化的角度将散花镇村镇等级体系划分为城镇/集镇、中心村、发展村和一般村。其中,城镇和集镇应加强产业合理布局和基础设施建设,体现辐射带动作用,优化村镇网络联系;中心村要合理规划工农业,强化与城镇和集镇等经济中心的空间联系,推进城乡统筹发展;发展村要考虑到其区位和资源禀赋条件,因地制宜确定发展方向;一般村着重发展现代农业,推动农业产业化与规模化发展。研究丰富了村镇等级体系规划的理论,对优化城乡资源配置、统筹城乡发展具有指导意义。
[Abstract]:Based on the improved gravity model, the spatial interaction pattern of 43 administrative villages in Sanhua Town, Xishui County, Hubei Province is analyzed, and the hierarchical system of villages and towns is classified quantitatively according to the potential index and node degree of village network. The development strategy was discussed. The results showed that Sanhua Town formed three distinct regions: southwest region, provincial road S201 line and eastern region. The comprehensive strength of administrative village in southwest region was 71.92, the reachability was 19.39 mins, which was better than the mean value of town area. The potential index and node degree are mostly I and so on, the villages and villages are closely connected and are the center of the village and town network, the comprehensive strength of the administrative villages along the provincial road S201 is 66.44, the potential index is slightly lower, and the potential index is II, but they benefit from the good traffic location. The reachability is 19.20 mins, the node degree is mostly I, the connection between villages and villages is extensive, the eastern region is weak, the comprehensive strength of administrative villages is 54.06, the traffic is backward, the reachability is only 27.23 mins, the potential index and node degree are mostly III and so on, the villages and villages are loosely connected. According to the potential index and node degree and from the point of view of optimizing the network structure and function of village and town, the hierarchical system of Sanhua town is divided into town / market, central village, development village and general village. Cities and towns and market towns should strengthen the rational layout of industries and the construction of infrastructure, embody the role of radiation driving, optimize the network links between villages and towns, and strengthen the spatial links with economic centers such as towns and towns, and the central villages should rationally plan industry and agriculture, and strengthen the spatial links with economic centers such as towns and towns. To promote the overall development of urban and rural areas; to develop villages to take into account their location and resource endowment conditions, to determine the direction of development according to local conditions; and to focus on the development of modern agriculture in general villages, The study enriches the theory of the planning of the village and town hierarchy system, and has guiding significance for optimizing the allocation of urban and rural resources and coordinating the development of urban and rural areas.
