基于小城镇生活圈的城乡公共服务设施配置优化--以辽宁省瓦房店市为例

Urban and Rural Public Service Facilities Allocation Optimization Based on Small Town Life Circle:Taking Wafangdian City of Liaoning Province as an Example

目前国内关于生活圈理论的应用,主要集中在宏观都市圈层面城市间的通勤圈,以及微观社区层面城市居民日常生活圈,而中观层面构建生活圈的相关研究较少。本文试图以辽宁省瓦房店市为例,在中观层面通过对小城镇生活特征进行总结,按照公共服务设施的使用功能特征构建基本生活圈和品质生活圈两类圈层,利用GIS软件可达性分析各城镇的辐射范围,空间上落实两类圈层,结合各类设施时间特征和功能特征,以及城镇的功能特色,完善城乡公共服务设施配置项目,同时对中心城市用地布局的调整提出建议。通过本文的研究希望可以对完善全国广大小城镇公共服务设施的配置提供一个可以考虑的修正因素,为国土空间规划体系下公共服务要素配置提供新的工作思路。

At present,the application of life circle theory in China mainly focuses on the commuting circle between cities at the level of macro metropolitan circle,and the daily life circle of urban residents at the level of micro community,lacking the research on the construction of life circle at the meso level.Taking Wafangdian City in Liaoning Province as an example,this paper attempts to summarize the life characteristics in small towns at the meso level,and construct two kinds of circles of basic life circle and quality life circle according to the use function characteristics of public service facilities,by analyzing the radiation scope of each town using the accessibility of GIS software,implementing two kinds of circles in space,and combining the time characteristics and function characteristics of various facilities and towns,in order to improve the urban and rural public life circle.Meanwhile,suggestions are put forward for the adjustment of the land layout of the central city.Through the research,this paper hopes to provide a correction factor that can be considered to improve the allocation of public service facilities in large and small towns in China,and to provide a new working idea for the allocation of public service elements under the territorial spatial planning system.
