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。In the Sanhua Town of Xishui County in Hubei Province, an improved gravity model was applied to analyze the spatial interaction patterns of 43 administrative villages of the Sanhua Town, and quantitatively divided the town- and-village hierarchy in terms of the potential index and the vertex degree of the town-and-village network. In turn, the individual development strategies for the divided hierarchical components were proposed and discussed. Our results showed that there were three significantly differentiated regions formed, i.e., the southwest region, the region along the S201 provincial highway and the east region. In the southwest region, the accessibility and comprehensive strength of administrative villages, overmatching the averages of township regions, were 19.39 min and 71.92, respectively. And, their potential index and vertex degree were mostly in Class I with a close village-to-village connection, acting as the center of the town-and-village network. For the administrative villages along the S201 provincial highway, a lower comprehensive strength （a score of 66.44） and a potential index （a level of Class II） were recorded. Whereas, because of their convenient transportation location, their accessibility reached 19.20 min, and their vertex degree was mostly in Class I, indicating that they enjoyed wide connections among villages. Since the east region presented a poor strength with a score of 54.06 and a backward transportation condition with accessibility of 27.23 min, most of villages in this region had their potential index and vertex degree in Class III. The loose village-to-village connection was found to marginalize the east region in the town-and-village network. Therefore, the town-and-village hierarchy of the Sanhua Town was divided into four levels according to the potential index and vertex degree and from the perspective of network structure and functional optimization： town/market town, key village, developing village, and ordinary village.
