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 increasing appeal for environmental protection, people are paying more and more attention to the disposal of rubbish, one of the environmental pollutants. It is very important that the site selection be carried out throughout the construction of the landfill. The selection of ETM + + remote sensing image to extract the basic geographic information, combined with the landfill site construction standards, the use of GIS spatial analysis function analysis of several candidate sites for the site. Analytic Hierarchy Process (AHP) was used to select the relevant evaluation indexes, and fuzzy comprehensive evaluation model was established to evaluate several candidate areas. The results of the scoring confirmed that each candidate landfill met the requirements of building site, and the highest score was screened as the best site . The scheme is scientific and reasonable, with a view to providing reference for the landfill’s investment and construction.
