摘　　要：生活垃圾填埋场既是环境保护的基础设施,同时也是潜在的污染源。其选址需要考虑自然条件和社会条件等因素。利用GIS的空间分析功能,根据研究区域的实际情况,按照填埋场选址的要求,进行评价因子的筛选,选定填埋场与主要水体之间的距离、地面坡度及土地利用类型3个影响因素作为评价因子,运用层次分析法,以5 m×5 m的栅格大小为评价单元,对三个图层的每个栅格进行重新赋值,根据专家打分确定每个评价因子的权重,最终得出评价区域内各栅格的适宜性指数,确定了最佳选址区域。A municipal solid waste( MSW) landfill is not only environmental protection infrastructure,but also the potential sources of pollution. Therefore,the natural and social conditions should be taken into account in the site selection of a landfill. This paper uses GIS spatial analysis function to select three factors,the distance between the landfill and water surface,ground slope and utilizing type of land,as evaluation factors. The research region was divided into 5 m × 5 m grid size as the evaluation unit using the analytic hierarchy process. Each raster of the three layers was reassigned with values. The weights of each evaluation factors were determined by the scores of experts. This paper concluded the best feasible raster for constructing MSW landfill in the research region based on the integrated score of each regional raster.
