The siting of Municipal Solid Waste (MSW) landfills in Greece is a difficult process due to land resource limitations, the country's mountainous, insular and primarily water permeable terrain as well as an exacerbated public opposition (NIMBY syndrome). A GIS-based methodology is presented here with the goal to identify and rank the candidate landfill sites for the entire island of Lesvos. The initial step of the methodology comprises a GIS-based spatial analysis that uses 10 criteria, by excluding all areas unsuitable for any waste disposal activity. The pre-selected areas are then further assessed by fieldwork and candidate landfill sites are determined. The candidate sites are ranked using 19 criteria with predefined weight coefficients on a 0 to 10 grading scale. The weight coefficients are estimated for each criterion using the Analytic Hierarchy Process (AHP), while the grading scheme is based on pre-defined guidelines. An overall suitability index is produced for each candidate site allowing comparison and best case selection. A case study for the island of Lesvos is presented here, in which eight candidate landfill sites were finally selected and ranked. Social factors highly determined the ultimate selection of the site in Lesvos, since the third rather than the first site suggested by the methodology, was finally approved by local authorities.
由于土地资源有限、希腊多山且岛屿众多以及主要为透水地形，再加上公众反对情绪加剧（邻避综合征），在希腊选址建设城市固体废弃物（MSW）填埋场是一个艰难的过程。本文提出了一种基于地理信息系统（GIS）的方法，旨在识别莱斯博斯岛全岛的候选填埋场并对其进行排名。该方法的初始步骤包括基于GIS的空间分析，该分析使用10个标准，排除所有不适用于任何废物处置活动的区域。然后通过实地考察对预选区域进行进一步评估，并确定候选填埋场。使用19个标准对候选场地进行排名，在0到10的评分尺度上具有预定义的权重系数。使用层次分析法（AHP）为每个标准估计权重系数，而评分方案则基于预定义的指南。为每个候选场地生成一个总体适宜性指数，以便进行比较和选择最佳方案。本文介绍了莱斯博斯岛的一个案例研究，最终选择并排名了八个候选填埋场。社会因素在很大程度上决定了莱斯博斯岛场地的最终选择，因为最终获得地方当局批准的是该方法建议的第三个场地，而非第一个场地。
