城乡共生视角下的村镇建设格局优化--以江苏省灌云县为例

Optimization of the town-village construction pattern from the perspective of urban-rural symbiosis:A case study of Guanyun county,Jiangsu province

城乡融合发展是乡村发展滞后背景下新的时代命题,村镇建设格局优化是破解乡村发展问题的重要抓手,其研究具有重要的理论和实践意义。基于城乡共生视角,以苏北灌云县为例,综合运用断裂点模型、社会网络分析法和场能模型,开展村镇建设格局优化。结果表明:(1)城乡共生视角下,村、镇的综合质量是共生基质,村镇之间相互作用、交流的时间和距离成本是共生界面,结合村镇的共生基质和共生界面进行共生选择,可指导村镇建设格局优化;(2)顾及镇质量、中心性和网络凝聚子群,确定灌云县村镇等级,利用改进的场能模型,通过测算县城及各镇的空间场能,完成村镇共生体构建,形成相互作用的城乡共生的县城—镇—村等级体系;(3)重构村庄引力矩阵并在村之间搭建有向连接线,发现包括后埠村、深沟村、东徐村等25个村与其他村庄的联系微弱,有待进一步调整,根据城镇辐射范围和村庄引力联系,形成优化调整方案,通过比较各村庄的点出度与点入度,将村庄划分为重点村和一般村,完成村镇建设格局优化。

Urban-rural integration is a new era proposition in the context of the backwardness of rural development.Optimizing the town-village construction pattern is a fundamental way to address rural development problems,which is of immense theoretical and practical significance.This paper adopts a comprehensive approach using the fracture point model,social network analysis method,and field energy model from the perspective of urban-rural symbiosis to restructure the town-village construction pattern in Guanyun county,located in northern Jiangsu province.The results demonstrate that:(1)The comprehensive quality of villages and towns is the symbiotic substrate,and the time and distance cost of interaction and communication between them is the symbiotic interface under the perspective of urban-rural symbiosis.The symbiotic substrate and interface of villages and towns can be combined for symbiotic selection to guide the optimization of the town-village construction pattern.(2)Based on town quality,centrality,and network cohesion subgroups,the grading of villages and towns in Guanyun is determined.The improved field energy model is utilized to establish town symbionts by calculating the spatial field energy of the county and each town,forming a county-town-village hierarchy of mutual urban-rural symbiosis.(3)The village gravity matrix is reconstructed,and a directed connection line is established between villages.It is observed that 25 villages,including Houbu,Shengou,and Dongxu,have weak connections with other villages,which require further adjustments.Based on urban radiation range and village gravity connections,an optimization adjustment plan is developed to optimize the town-village construction pattern.
