چکیده مقاله :
Solid waste is an integral part of human life and the production of its types in different quantities and qualities is one of the most important environmental problems of the present age. To prevent environmental pollution in the community, waste must be disposed of hygienically and engineeringly. One of the methods of waste disposal is engineering waste disposal method. In this study, our emphasis is on the impact of ecological factors on the location of urban solid waste landfills in Qazvin city using spatial analysis in GIS environment for optimal location of municipal landfills. For this purpose, the required digital data was collected and then transferred to the ArcGIS environment. After creating the database, multi-criteria analytical decision-making models were implemented, the reliable method of AHP hierarchical analysis. As a result, by using the AHP method, hierarchical criteria have been used to locate a suitable sanitary place for landfilling of generated waste in Qazon city, and the most optimal place has been selected from 4 proposed places for sanitary landfilling of waste.
