| In Zanjan city with high rate of population growth and physical development, every day 270 tons of solid waste with different compounds enters into the biological cycle of the city. The current location of disposed waste at inappropriate local is in Mehtrchay the region in the southwest city. In addition, waste disposal method was inappropriate and causes vital sources of pollution such as air, water, soil and landscape. On the other hand, disruption of daily life of those residents near waste disposal sites are necessary to locate for new location waste disposal. In this study, by using fuzzy logic the aim was to determine the value and different weight criteria affecting the location of municipal solid waste landfill in Zanjan by GIS to design a model and to select disposal site. Parameters used were slope, topography, fault lines, distance from population centers, distance from surface and underground water resources, distance from access roads, type of soil and rocks, land use area, and land capability analysis was thereby analyzed. Finally, after overlapping the layers three sites as quite appropriate, suitable and moderately suitable were identified. After the evaluation, overlapping layers were obtained by Weighted Perfect Choice 35 kilometers from Zanjan in northwest of the Khalkhal road as Center for hygine solid wastes landfill site in Zanjan. Results of the analysis and control of land is largely satisfactory. |
