基于引力可达性的公共服务设施公平性分析模型——以福建长汀为例

Based on the Gravity of Accessibility of Public Service Facilities Fairness Analysis Model:Take Fujian Changting as an Example

公共服务设施的完善配套已成为社会文明进步的标志,其空间分布的公平程度深刻影响着城市居民的居住环境和生活质量。本文引入了威布尔的引力模型,借助Arc GIS软件平台,尝试构建基于引力可达性指数的公共服务设施公平性分析模型,并以福建长汀为例进行了实证研究,以期为公共服务设施规划提供实用的分析方法和技术支撑。

Perfectly allocated facilities have become a symbol of social civilization and progress .The equity level of public service fa-cilities’ spatial distribution influences city dwellers ’ living conditions and quality intensely .This paper introduces Weibull ’ s Gravity Model, tries to build an analysis model on equity level of public service facilities based on gravity accessibility index with ArcGIS plat -form, and take Changting as a case study, so as to provide one kind of analysis method for the planning of public service facilities .
