Locating the optimal municipal solid waste rubbish landfill using model (AHP) in GIS

Increase the production of daily urban waste is one of the major threats to the health of the global environment. Nowadays، most urban waste disposal method in many countries، including Iran. Development and application of research and analysis methods are described. In this study have used software، SPSS and ARC/GIS، 10 for spatial statistical analysis. The method of research was data collecting in some articles، magazine and books. The purpose of this paper is to determine appropriate locations for waste disposal in urban areas in Tonekabon. Process of locating suitable land for landfill waste، 9 layers، including layers of information away from urban and rural areas، groundwater levels، distance from the river، land use، soil type، rainfall، distance from communication، land use and slope classification by using overlapping process using analytic hierarchy process (AHP) with weights derived effective positioning operation was performed Based on the results obtained in this study، total area is 34. 12 hectares of lowland Branch extremely important strength - paired region holds 0. 1 percent. 1827. 90 hectares which is 6. 95 percent of the region possesses very strong in this area of 9904. 82 hectares which is 37. 70% of the low important priority area of approximately 27. 53% of the regional average of 7233. 63، and the region with strong significance with an area of 7267. 35 hectares، with 27. 66 percent and 6. 95 percent 1،827،90 hectares is the best area which is proposed for solid waste land fill.
