Abstract :

Background and Objective: Landfill site selection is essential in urban development plans. Sustainable development can mean the identification of the unique characteristics and assets of a region which highlights the advantages of each region and leads the regional beneficiaries and resources to the perspective emerging from land use planning. Therefore, the environmental baseline studies based on GIS technology and other models related to spatial data analysis for identification of  the area, could be seriously addressed. Natural landscape referes to usefulness of human activities in the nature, especially in the areas which are covered with plants or artificially drawn, On the other hand study of urban landfills from natural landscape view has a very important effect on landfill site selection, This seeks to find the optimum model for urban landfill site selection in line with land use and sustainable development. Methods: In this study, the landfill in Bushehr was visted and features such as the spacing of wells, residential communities, industrial facilities, access roads, airports, historical and religious centers, areas of biological importance, hunting and habitat zones for birds, geographic coordinates, wind, topography, geology, land use, soil, watercourse, groundwater depth, floodplain, surface water and slope were studied. After the necessary processing using the software area maps were prepared. The obtained map was transferred to Arc GIS software. The maps with Clip functions related to the intended zone were extracted for all the digital files. The basic maps in, 9/2 Arc GIS were determined in the study area using Buffer function, after classification and finally overlaying each maps, the finalized, was obtained. The final map was prepared according to the classification table with three values of poor, average and good. Results: The results showed that the study area is 57% suitable, 40% poor and 3 % average in terms of spatial planning and sustainable development criteria. According to population growth in Bushehr city, the amount of waste production in a 20-year horizon (2009-2026) of the area required for sanitry landfilling in the study area was calculated 1176261/2 hectare. Knowing landfill has an area of 2 hectare, it was revealed that the place does not meet the needs for 20 years.
