Selection of landfill site is a complex process and needs many diverse criteria. The purpose of this paper is to evaluate the suitability of the studied site as landfill for MSW in Karaj. Using weighted linear combination (WLC) method and spatial cluster analysis (SCA), suitable sites for allocation of landfill for a 20-year period were identified. For analyzing spatial auto-correlation of the land suitability map layer (LSML), Maron's I was used. Finally, using the analytical hierarchy process (AHP), the most preferred alternative for the landfill siting was identified. Main advantages of AHP are: relative ease of handling multiple criteria, easy to understand and effective handling of both qualitative and quantitative data. As a result, 6% of the study area is suitable for landfill siting and third alternative was identified as the most preferred for siting MSW landfill by AHP. The ranking of alternatives were obtained only by applying the WLC approach showed different results from the AHP. The WLC should be used only for the identification of alternatives and the AHP is used for prioritization. We suggest the employed procedure for other similar regions.
垃圾填埋场的选择是一个复杂的过程，需要考虑许多不同的标准。本文旨在评估研究区域作为卡拉季市垃圾填埋场的适宜性。使用加权线性组合（WLC）方法和空间聚类分析（SCA），确定了 20 年内可用于分配垃圾填埋场的适宜地点。为了分析土地适宜性图层面（LSML）的空间自相关，使用了 Maron 的 I 指数。最后，使用层次分析法（AHP）确定了垃圾填埋场选址的最优选址。AHP 的主要优点是：相对容易处理多个标准，易于理解和有效处理定性和定量数据。结果表明，研究区域的 6%适合进行垃圾填埋场选址，AHP 确定第三备选方案为最适合的垃圾填埋场选址。仅通过应用 WLC 方法对备选方案进行排名，结果与 AHP 不同。WLC 仅应用于备选方案的识别，而 AHP 则用于优先级排序。我们建议在其他类似地区采用所采用的程序。
