基于AHP的福州市垃圾中转站空间布局分析与评价

Spatial Layout Analysis and Evaluation of Garbage Transfer Stations in Fuzhou Based on AHP

为提高城市垃圾管理系统运转效率,针对垃圾转运系统中中转站选址问题,采用层次分析法(AHP)构建福州市城区垃圾中转站空间布局现状评价体系,利用欧氏距离分析、缓冲区分析和叠置分析等GIS空间分析方法进行适宜性评价并提出优化方案。研究结果表明部分现有站点处于适宜性等级较低的区域内,研究有效解决了垃圾中转站选址不合理问题,为政府决策部门合理规划垃圾中转站选址提供有益参考。

In order to improve the operation efficiency of urban garbage management system, solving the location problem of garbage transfer station in garbage transfer system, the improved analytic hierarchy process(AHP) was used to construct the evaluation system of spatial layout status of garbage transfer station in Fuzhou, the GIS spatial analysis methods such as Euclidean distance analysis, buffer analysis and overlay analysis were combined to analyze the current situation of the spatial layout of garbage transfer stations in the urban area of Fuzhou, and the suitability evaluation and proposed optimization scheme were performed. The result shows that some stations are in areas with lower suitability levels. This method can be effectively used to solve the problem of unreasonable location of garbage transfer station and provide a useful reference for government decision-making departments to plan the location of garbage transfer station reasonably.
