Document Type : Research Article



منابع آب و خاک Water and Soil Resources از From مهمترین The most important کالاهای Goods ضروری necessary در At هر Each شهر City یا Or کشور Country محسوب Is می‌گردد Is که That دارای have مصارف Expenditure گوناگونی variety می‌باشد. Is. از مهم ترین The most important موارد Items مصرف Consumption این منابع These resources مصرف Consumption آب Water شرب، Drinking, مصارف Expenditure خانگی، Homemade, استفاده Use در At فعالیت‌های Activity کشاورزی Agriculture و And دامداری، Livestock, صنعتی Industrial و And معدنی Mineral است. Is. هدف از مقاله حاضر ارزیابی و تحلیل وضعیت منابع آب و خاک در مناطق شهری تهران می‌باشد. The purpose of this paper is to evaluate and analyze the water and soil resources in urban areas in Tehran. پژوهش حاضر به لحاظ روش تحقیق با The present research method تبعیت Adherence از From ماهیت nature مسئله، Question, روشی Way تحلیلی- Analytical توصیفی Descriptive است و داده‌های مورد نیاز از طریق مصاحبه و پرسسشنامه جمع آوری شده است. and required data were collected through interviews and questioners. جهت وزن دهی به زیرشاخص‌ها از مدل تحلیل سلسله مراتبی و نرم افزار Expert choice، جهت ترسیم نقشه‌ها و همپوشانی و تلفیق زیرشاخص‌ها از نرم افزار Arc GIS و جهت تحلیل از مدل نیروی محرکه، فشار، وضعیت و پاسخ استفاده شده است. For weighting the sub-criteria model and software AHP Expert choice, to map and overlying sub Arc GIS software and to the analysis of the driving force, pressure, state and responses are used. بر طبق یافته‌ها و بر اساس شاخص عملکرد محیطی ( EPI )، مقدار شاخص منابع آب و خاک از 17.3 تا 41.9 متغیر بوده است و منطقه 20 دارای بدترین شرایط و مناطق 1 و 22 دارای شرایط مناسبی بوده اند. According to the findings, based on the environmental performance index (EPI), soil and water resources of 17.3 to 41.9 indexes varied and regions 1 and 22 regional and 20 the worst conditions were suitable. در مجموع و با رویهم گذاری لایه‌های زیرشاخص‌ها مشخص گردید که منطقه 20 دارای شرایط بسیارنامناسب و نیز دارای عملکرد بدتری در بین مناطق بوده است و اکثر مناطق (9 منطقه) در شرایط نامناسب قرار گرفته اند و دو منطقه 1 و 4 از شرایط بسیار مناسبی برخوردار می‌باشند. A total of sub-layers was determined by overlaying the area 20 very appropriate conditions and also has been performed worse across regions and most of the regions (9 regions) are in poor condition and two regions 1 and 4 of the conditions rather good. به طور کلی 5 منطقه در شرایط مناسب قرار داشته اند و 17 منطقه دارای شرایط نسبتاًمناسب تا بسیار نامناسب و دارای عملکرد بدی بوده اند. In general, five regional and 17 areas under appropriate conditions have been very unfavorable conditions relatively appropriate to have a bad performance.
