چکیده

شهر مهاجران به عنوان اولین شهر جدید در استان مرکزی بنا شد، و مطابق اصول شهرسازی و معماری احداث شده است. هدف این مطالعه ارزیابی مقدماتی وضعیت محیط‌زیستی شهر مهاجران است. این مطالعه با استفاده از رویکرد تحلیل چند معیاره (MCDA)، روش ANP، نرم افزار Super Decisions با 8 گزینه،7 معیار و 18 زیر معیار انجام شد. معیارها شامل انرژی و دی اکسیدکربن، پسماند و بازیافت، کیفیت هوا، آلودگی صدا و آلودگی نوری، مدیریتمحیط‌زیستی، حمل و نقل، کاربری زمین و ساختمان (فضای سبز)، آب و فاضلاب هستند. ارزیابی معیارها از طریق بازدید میدانی، دریافت اطلاعات از ارگان‌‌ها و همچنین مصاحبه با مردم شهر، توزیع پرسشنامه آنلاین، تفسیر و مقایسه تصاویر ماهواره‌ای سال‌‌های 2000 با 2020 منطقه، تعیین ضرایب انتشار آلاینده‌‌های ناشی از مصرف گاز طبیعی شهر مطابق EPA انجام شد. ارزیابی معیارها با روش ANP نشان می‌‌دهد وزن معیار کاربری زمین و ساختمان (22/0) و فاضلاب (18/0) بیشتر از 5 معیار دیگر است. وزن زیر معیار سرانه فضای سبز (25/0) و دسترسی به شبکه فاضلاب (15/0) بیشتر از سایر زیر معیارها است. منطقه 2 با وزن (162/0) سبز‌‌ترین و منطقه 4 با وزن (079/0) کمترین سبزی را نسبت به سایر مناطق شهر مهاجران هستند.

چکیده [English]

The Mohajeran city was built as the first new city in Markazi province, and was built according to the principles of urban planning and architecture. The purpose of this study is a preliminary assessment of the environmental situation of the Mohajeran city. This study was performed using multi-criteria analysis (MCDA) approach, ANP method, Super Decisions software with 8 options, 7 criteria and 18 sub-criteria. Criteria include energy and carbon dioxide, waste and recycling, air quality, noise and light pollution, environmental management, transportation, land and building use (green space), water and wastewater. Evaluation of criteria was done through field visits, receiving information from organizations as well as interviews with the people of the city, distributing online questionnaires, interpreting and comparing satellite images from 2000 to 2020 in the region, determining the emission coefficients of pollutants from natural gas consumption according to EPA. The results of the evaluation of criteria by ANP method shows that the weight of land and building land use criteria (0.22) and wastewater (0.18) is more than the other 5 criteria. The per capita weight of green space (0.25) and access to the sewerage network (0.15) is more than other sub-criteria. Area 2 with a weight of (0.162) is the greenest and Area 4 with a weight of (0.079) is the greenest compared to other areas of the city.
