Locating the landfill site of Ardakan city using decision-making modeling Multi-criteria in GIS environment

Choosing a landfill site has been one of the most important issues in urban management in the middle and last decades of the 20th century. This research was conducted with the aim of locating the non-hazardous waste landfill site in Ardakan using multi-criteria decision making modeling in GIS environment. In this research, 10 important factors for locating waste landfills such as: land use, slope, height, soil, distance from residential use, roads, rivers, springs, wells and villages in the area were used and to prepare area map. AHP model was used for the final classification. According to the results obtained from the multi-criteria hierarchical analysis method with Expert choice software, the weight of land use criteria, slope, height, distance from residential use, soil, distance from roads, rivers, springs, wells, distance 166, 0, 033, 0, 040, 0, 232, 0, 083, 0, 144, 0, 063, 0, 071, 0, 05, 0, 119 and 0 were obtained from the villages for the studied area. .In this area, the distance criterion from residential areas has the highest weight and the slope criterion has the least impact on the location of waste burial areas. By examining the final map, the most suitable areas for landfilling are located in Ardakan in the northwest, west, and southwest, and a few parts of the areas near the center of the range
