摘要
随着环境保护的呼吁声越来越高,人们对环境污染物之一的垃圾的处理越来越关注,选址工作在垃圾填埋场的整个建设过程中的地位非常重要。本次选用ETM++遥感影像提取基础地理信息,结合垃圾填埋场建址的标准,利用GIS空间分析功能分析出适合场址的几个候选区。利用层次分析法选取相关评价指标,建立模糊综合评判模型对几个候选区进行评价;得分结果验证出每个备选填埋场均满足建场要求,得分最高者被筛选为为最佳场址。该方案科学合理,以期对垃圾填埋场的投资建设提供参考。
With the growing calls for environmental protection, it is very important to select garbage landfill site throughout the construction process, for waste disposal which is one of the environmental pollution being concerned. In the paper, the basic geographic information was extracted from ETM＋＋ remote sensing images. Based on the building criteria of garbage landfill site, it analyzed several candidate regions using spatial analysis functions of GIS. Moreover, it selected some related evaluation index by Analytic Hierarchy Process to establish the fuzzy comprehensive evaluation model. The evaluated results of candidate regions showed that all alternative landfill sites met requirements, so the location of highest scores was selected as the best site. The program could be scientific and rational to investment and construction of landfills for reference.
