摘　　要：以对比研究层次分析法和模糊评判法在垃圾填埋场选址中的应用特征,并探究两者综合应用的可能性为目的,以自然地理、地质环境、工程地质条件及环境保护为评价标准,对广州市4个拟建填埋场进行了适宜性评价。在层次分析法确定的权重值的基础上,利用模糊评判法进行计算,最终确定兴丰填埋场为最佳场地,评价结果与实际应用情况相符。另外,通过对比分析发现,在参数选择与定量化方面,模糊评判法评价结果的准确性更高,而层次分析法的计算工作量较少;在评判结果的适用性方面,层次分析法的评判结果与实际相符性程度更高。研究表明,两种方法结合起来应用于垃圾填埋场的选址是可行的,且可提高评判结果的准确度。In order to compare and study the application characteristics of AHP and fuzzy evaluation method( FEM) in landfill siting,as well as the possibility of combining the two methods,the suitability of four selected landfills( proposed) in Guangzhou was evaluated with natural and geographical conditions, geological conditions, engineering geology and environmental conditions as the evaluation criteria. Xingfeng Landfill Site was determined to be the best ultimately,which matches with the actual application after the calculation of FEM based on weighting determined by AHP. Through comparision,the accuracy of FEM in selection of parameters and the quantitative is higher. While AHP is more convenient in the computation. The result of AHP is better consistent with the actual in judging the applicability of the results. The research shows that the comprehensive application of the two methods is feasible and can improve the accuracy of evaluation results.
