انتخاب محل دفن پسماند ها (لندفيل) يكي از مراحل مهم در مديريت پسماندهاي جامد شهري مي باشد . با توجه به اثرات مخرب زيست محيطي، اقتصادي و اكولوژيكي لندفيل ها، انتخاب محل دفن بايد با دقت و طي يك فرايند علمي صورت گيرد. اين تحقيق با هدف تعيين مكان هاي مناسب دفن پسماند شهري شهرميانه بابررسي هاي زمين شناسي زيست محيطي و با استفادهازقابليت هاي نرم افزارGIS و فرايند تحليل سلسله مراتبي( AHP) اجرا شده است. در اين مطالعه جهت انتخاب محل مناسب براي احداث لندفيل جديد شهر ميانه،معيارهاو ضوابط انتخاب مكانهاي مناسب براي دفن بهداشت يپسماندهاي اين شهر مانندخصوصيات زمين شناسي،راه هاي دسترسي،نقشه شيب و جهت شيب، گسلها، نقشه كاربري اراضي،فاصله از مراكز شهري و روستائي،نقشه خاك منطقه، نقشه شبكه هيدروگرافي و آب هاي زيرزميني و نيز نقشه مسير خطوط انتقال گاز شناسايي گرديدند. جهت تهيه نقشه ي قابليت مكان مناسب دفن پسماند، ابتدا مناطق ممنوعه حذف شد. از طريق پرسشنامه با استفاده از نظرات كارشناسان و متخصصان AHP، اهميت و وزن معيارها تعيين گرديد و سپس با استفاده از 12 لايه اطّلاعاتي به روش وزن دهي به معيارها و تحليل وزن ها در محيط GIS، نقشه هم وزن معيارهاي مختلف بدست آمد .در انتها با ادغام اين نقشه ها بهترين مكان براي دفن پسماندهاي شهر ميانه انتخاب گرديد.

One of the most problem of human societies is, production of types of waste solid materials in different qualities and quantities and its discharge. Discharge is the simplest method and in many reigns is low –cost method of discharge. Main goal of discharge is secure and long lasting of solid waste material discharge regard to health and environment. Selecting of place of landfill is one of the important stage in management of urban solid wastes. According to destructive environmental effects, economic and ecological of land fill, and choice of landfill should be fulfilled carefully. This research is done for this purpose to determining proper places of urban waste disposal of Mianeh city by using of hierarchical method (AHP). The current place of urban waste disposal of Mianeh city located at 13 kilometer distance in west of city and adjacent to Mianeh_Hashtrud road on the hills of Dashkasan regions with 3 kilometers motorable track and it becomes asphalt way after 10 kilometers. In this research, criteria and conditions of selecting proper places are identified for healthy landfill of waste disposals such as geology characteristic, availability ways, slop map, faults, land use map, distance of rural and urban centers, soil map of region, hydro-graphy drainage map, groundwaters and gas pipeline ways. For providing talented ability exclusion zones are deleted at first and by using of twelve information layers by weighting method to each ones and analyzing of these weights in GIS environment map obtain different criterion, then best places were selected by combination of these maps. These places located in north, northeast, southwest and southeast. From received regions, the best place is recognized and after field review, this area was confirmed final. This area is located in 8 kilometers of north and northeast and in adjacent to Mianeh _Tark and it has 2 Kilometer motorable track and after 6 kilometer. The lithology of this area mainly include marls and sandstone. It is Also, outside of Aquifer limit, and it is suitable from rural regions.
