This study used GIS based Multi-criteria Decision Analysis (MCDA) approach for evaluating the most environmentally suitable landfill sites in the study area. The weights of relative importance of the factors guiding landfill siting were estimated using pair-wise comparisons in AHP. The maps showing suitable landfill sites were generated applying a weighted linear combination (WLC) in GIS using a comparison matrix to aggregate different significant scenarios associated with environmental and economic objectives. To determine the appropriate areas where landfill sites can be located, thematic maps for all the criteria were generated using GIS. A final map was produced showing suitability for the location of the landfill sites. The suitable sites having an area equal to or above 4 ha at one place and 90% of which is barren land were considered suitable for landfill. The selected candidate sites were ranked to get the most desirable sites for landfill.

这项研究使用基于GIS的多标准决策分析（MCDA）方法来评估研究区域内最适合环境的垃圾填埋场。使用AHP中的成对比较来估算指导垃圾掩埋场址的因素的相对重要性的权重。使用比较矩阵在GIS中应用加权线性组合（WLC）生成了显示合适的垃圾填埋场的地图，以汇总与环境和经济目标相关的各种重要情景。为了确定可以放置垃圾掩埋场的适当区域，使用GIS生成了所有标准的专题图。绘制了最终地图，显示出适合填埋场地点的位置。一处面积等于或大于4公顷且其中90％为贫瘠土地的合适场所被认为适合填埋。对选定的候选地点进行排名，以获得最理想的垃圾填埋场。
