Abstract :

Choosing landfill is one of the most important steps in the management of municipal solid waste and according to environmental impact, ecological landfill disposal site selection should be done carefully and in a scientific process.Usage of the tools and technology seems to be necessary to find a suitable place to bury it.Nowadays, GIS is widely used in environmental planning.In this study, to locate waste disposal site in Ilkhchi, different information layers of land use, vegetation, slope, lithology, soil texture, distance from the town, population centers, water supplies (aqueducts, wells and springs), canals, mines, access roads (primary and secondary)  is used in power transmission lines.In order to map the areas removed Astdaddary first eight information layers on the weighting method using Analytical Hierarchy Process (AHP) , final map is prepared. According to the study, all areas are suitable for construction of landfill in East study area. Finally, the environmental effects of each of the zones of the zone with the lowest environmental impacts as the best location for the city's landfill Ilkhchi is selected.Finally, by studying the environmental effects of each zone, the zone with the lowest environmental impact is selected as the best location for the landfill in Ilkhchi.
