The Optimal Location of the Lighvan Village Landfill Using Analytic Network Process (ANP)

Abstract

Environmental protection in rural areas is of the necessities in rural development. One of the important issues in rural areas is to find the appropriate landfill site. In this article, in order to assess the proper places for landfill in Lighvan village, corresponding geomorphological factors are provided and analyzed. In evaluating landfill site, GIS software and network analysis process modeling (ANP) are used. Five human-economic key factors of topographicalmorphology, climate-hydrology, soil-vegetation and geology are considered. These factors produce 12 layers of land use, distance from residential areas, and distance from the lines of communication, distance from fault, distance from the river, slope, elevation classes, and direction of slope, climate, soil, vegetation and the lithology. The appropriate landfill site is identified by using the layers and models in Arc Map. Results show that proper places allocate 23.87 and improper places allocate 21.13 percentage of the desired area. By zoning plan, appropriate places in the entire Lighvan village are introduced which can be used in future planning.
