Study of Proper Spatial Organization of Garbage Dumps in Dorud City Using GIS System and Fuzzy Logic

The aim of the present study is to identify suitable locations for landfills in Dorud city using GIS system and fuzzy logic. Descriptive-analytical research in the research of the criteria of the Environmental Protection Agency (IEPO) that are considered for this process, including topography, geology and... Using GIS and multi-criteria or fuzzy decision analysis has been used to solve the problem of mechanical landfill system and create a ranking of potential landfill areas. In this method, three steps are used to find suitable places, which include: linear weight combination, fuzzy logic approach and prioritization of potential sites that are ranked by the analytical hierarchical process after installation in the last step. Also, field observations confirm the suitability of the selected sites and therefore this method can be used in urban areas for the method of selecting the waste disposal site. Selected locations are considered to minimize environmental risk and human health problems. Also, the results indicate the application of the geographic information system in the production of the zoning map from the hierarchical analysis process of AHP and based on the zoning map, the best GIS points have been used. Then the field observations also confirm the suitability of the specified areas for landfilling.
