چکیده

مدیریت پسماند به کلیه برنامه‌ریزی‌ها و فعالیت‌هایی گفته می‌شود که در حوزه پسماند و به‌منظور کاهش، جابه‌جایی، تبدیل، بی‌خطرسازی یا امحا پسماند صورت می‌گیرد. سیستم مدیریت زباله از بخش‌های مختلفی تشکیل می‌شود. این سیستم را می‌توان به زنجیری تشبیه کرد که در صورت فقدان یک حلقه از آن، زنجیر ازهم‌گسیخته می‌شود. بنابراین عملکرد هر یک از بخش‌های مدیریت پسماند بر سایر قسمت‌ها تأثیرگذار خواهد بود. سایت دفن پسماند اهواز در نزدیکی روستای «صفیره» در بخش غیزانیه این شهرستان، از سال 1391 با تعطیل شدن مدفن قدیمی پسماند در منطقه «برومی» راه‌اندازی شده است. روزانه یک هزار تن زباله شهر به سایت پسماند اهواز منتقل می‌شود. طبق آخرین آمار اعلام شده میزان جمع‌آوری زباله در ۲۴ ساعت نزدیک ۸۰۰ تن است که با وجود زباله‌گردها و جمع‌آوری زباله‌های خشک توسط آن‌ها این میزان کمتر شده است. با توجه به موضوع تحقیق، روش تحقیق توصیفی- تحلیلی است. در این راستا ابتدا با استفاده از نرم‌افزار GIS به بررسی وضعیت دفن پسماند در شهر اهواز پرداخته شده است. سپس توزیع جغرافیایی مکان‌های مناسب در دفن پسماند در این شهر مورد بررسی قرار گرفته است. برای انجام کارهای تحلیلی، نقشه‌هایی که به‌صورت پلی‌گون هستند تبدیل به رستر و نقشه‌هایی که به‌صورت عوارض نقطه‌ای و خطی بوده‌اند با استفاده از فاصله اقلیدسی میزان اهمیت آن‌ها نسبت به مکان دفن پسماند مشخص شده است. در نهایت با استفاده از روش FAHP نقشه پایانی شامل بررسی موقعیت کنونی محل دفن پسماند شهر اهواز و مکان‌های پیشنهادی به دست آمده است. به‌منظور تجزیه و تحلیل داده‌ها از تحلیل‌های آماری و گرافیکی در محیط GIS و SPSS استفاده شده است. نتایج تحقیق مشخص نمود از لحاظ مکانی و محیطی سایت دفن پسماند صفیره در وضعیتی مناسبی قرار دارد و مشکلات شهر اهواز در رابطه با دفن پسماند مربوط به مدیریت صحیح آن است.

Extended Abstract
Introduction
Management in general is the art and knowledge of efficient and optimal use of resources to achieve the goal, and waste management or waste management is in fact all the planning and activities in the field of waste and in order to reduce, move, convert, Decontamination or disposal of waste takes place. Waste management system consists of different parts. This system can be compared to a chain that in the absence of a loop, the chain will be broken, so the performance of each waste management will affect other parts. Although the waste problem has been solved in many cities of the country and may have become a source of prosperity for the city,In the metropolis of Ahvaz, due to the lack of a clear strategy and proper investment in recent years, it has not been able to bring prosperity to the city and always a lot of garbage in the people, has caused a huge amount of dissatisfaction of citizens. In Ghizaniyeh section of this city, since 1991, with the closure of the old landfill in the "Broumi" area, it has been set up Non-disposal of garbage in a principled manner and according to the rules in this garbage site, provides the conditions for garbage to burn in this site and the smoke from this fire will burn the residents of Sofireh village and most of the villages of Ghizaniyeh section of Ahvaz city and east of this city. Has encountered a problem. One thousand tons of city waste is transferred to the Ahvaz waste site daily. The per capita waste production in the country is 700 grams per person, this per capita in Ahvaz is more than the national average per person. According to the latest statistics, the amount of garbage collected in 24 hours is close to 800 tons, which has decreased despite the fact that garbage collectors and dry garbage collect by them.
Material & Methods
According to the research topic, the research method is descriptive-analytical. In this regard, first, using GIS software, the situation of waste landfill in Ahvaz city has been studied, then the geographical distribution of suitable places for waste landfill in this city has been studied. For analytical work, maps that have been in the form of polygons have been turned into rasters, and maps that have been in the form of point and linear features have been determined using the Euclidean distance to determine their importance in relation to the landfill. In order to determine all the maps, the importance of classification has been applied to them. Finally, using the FAHP method, the weights obtained from this method are multiplied in the obtained layers, and the final map, which includes the current location of the Ahvaz landfill and the proposed locations, is obtained. In the next stage, using the opinions of experts living in Ahvaz, managerial, economic, environmental and social indicators have been studied. In order to analyze the data, statistical and graphical analyzes in GIS and SPSS were used.
Results & Discussion
The results of the study showed that in terms of location and environment, the ambassador landfill site is in a good condition and the problems of Ahvaz city in relation to waste disposal are due to its proper management . The studies of this study show that in the spatial survey of Safireh landfill, environmental criteria have been relatively observed. Among the landfills around the city of Ahvaz, from 5 very unsuitable to very suitable conditions, Safireh site is in a good condition, which can be said that the location of this site is suitable in terms of environmental characteristics.
