One of the most challenging tasks faced by many cities in implementing a solid waste management program is the selection of new landfills. Ideal landfill sites should have minimal impact on the environment and economy. This study presents an alternative method, in which the modified Analytical Hierarchy Process was applied with Geographic Information Systems to determine the most suitable landfill sites and thoroughly investigated the landfill site suitability map process, taking into consideration the economic criteria, such as slope and distance to roads, as well as environmental factors, including land use/land cover, geology/hydrogeology, distance to residential areas, distance to surface water and distance to protected areas, Aksaray province in central Anatolia of Turkey. According to the results of the study, environmental factors (W: 0.869769) were determined to be more important than economic factors (W: 0.130230). Eight percent of the study area was not suitable, 20% was lowly suitable, 14% was moderately suitable, 51% was suitable and 7% was highly suitable for landfill construction. Among the highly suitable areas, two alternative locations were identified in the southern part of the province of Aksaray. The first alternative (Alternative-I) has an area of ⁓184 km² and ~ 35 km away from the Aksaray city center, while the second alternative (Alternative-II) has an area of 3133 km², and ~ 65 km away from the city center. Both alternative areas are suitable within 30 years of waste storage period. The findings obtained from the study serve as a guide in the selection of landfills.

许多城市在实施固体废物管理计划时面临的最具挑战性的任务之一是选择新的垃圾填埋场。理想的垃圾填埋场应对环境和经济影响最小。本研究提出了一种替代方法，其中，将经修改的层次分析法与地理信息系统一起使用，以确定最合适的垃圾填埋场，并在考虑经济标准（例如坡度和距离道路以及环境因素，包括土地使用/土地覆盖，地质/水文地质，到居民区的距离，到地表水的距离以及到保护区的距离，土耳其中部安那托利亚的阿克萨赖省。根据研究结果，环境因素（W：0。869769）被确定为比经济因素更重要（W：0.130230）。研究区域的8％不适合，低水平为20％，中度为14％，适度为51％，高度适合于垃圾填埋场的为7％。在高度合适的地区中，在阿克萨赖省的南部确定了两个替代地点。第一种选择（Alternative-I）的总面积为⁓184km距离阿克萨赖（Aksaray）市中心约²公里，约35公里，而第二个备选方案（Alternative-II）的面积为3133 km ²，并且距市中心约65公里。两个替代区域都适合在废物存储期30年内使用。从研究中获得的发现可作为掩埋场选择的指南。
