| 摘 要： | 运用系统的观点对小城镇生活垃圾填埋场选址进行多因素、多层次的分析,建立了小城镇生活垃圾填埋场综合评判系统的层次结构模型,确定了小城镇生活垃圾填埋场布点的适宜度等级。以重庆市小城镇为研究对象,以区域性联合集中处理为前提,以22.2 km为县域镇区域联合半径,利用ArcCatalog和ArcMap软件对所收集到的数据进行了图形数字化、关键区域的提取、缓存区分析、建设地形适宜度分析和地质灾害区划分析,并进行了各影响因素图层的叠加计算和关键区域的叠加计算,最终得到了重庆市小城镇填埋场优化布点图,为有关部门提供决策支持。

| Abstract: | After multi-factor and multi-tiered analysis of the site selection of domestic garbage landfills in small town with a systematic angle of view, a hierarchical structured model of comprehensive evaluation system, which outputs the suitability grade of site selection of domestic garbage landfills, was established. Taking small towns in Chongqing as object of study, collected data were analyzed utilizing ArcCatalog and ArcMap software on the premise of regional combined and centralized treatment mode with a region radius of 22.2 km. Data analyses include figure digitization, key area extraction, cache analysis, topographical suitability assessment and geological disaster analysis. Influencing factor layers and key areas were also computed by repeated addition. As a result, a distribution map of small-town domestic landfills in Chongqing was drawn so as to provide reference and scientific basis for policy making. |
