چکیده
امروزه مسائل زیست محیطی به یکی از مهمترین چالش های برنامه ریزان شهری تبدیل شده است و توسعه لجام گسیخته شهری بر پیچیدگی آن افزوده است. برنامه ریزی با رویکرد تاب آوری می تواند در تمامی ابعاد، ظرفیت های لازم برای مقابله با آینده آشفته را ایجاد نماید. هدف این مطالعه، ارزیابی تاب آوری زیست محیطی محلات منطقه چهارده شهر تهران می باشد. در اصل 23 محله با انتخاب 5 شاخص زیست محیطی مورد بررسی قرار گرفته است. پنج شاخص مذکور توسط 30 نفر از خبرگان برنامه ریزی شهری از طریق تحلیل سلسله مراتبی AHP رتبه بندی و سپس تحلیل رابطه خاکستری وضعیت و جایگاه محلات منطقه 14 را در هر شاخص مشخص نمود. در نهایت خط نرمال 0.714 به عنوان امتیاز نهایی در کلیه شاخص ها ترسیم گردید که نشان می دهد 12 محله، از تاب آوری پایینی برخوردارند. با توجه به نتایج بدست آمده هرچه به سوی محلات غربی و جنوب غربی حرکت می کنیم، از میزان تاب آوری زیست محیطی کاسته می شود. این موضوع کاملاً با بافت فرسوده و تراکم جمعیتی منطقه هماهنگ است. بنابراین لازم است برنامه ریزان شهری بیش از اینکه بر توسعه فیزیکی تأکید نمایند، پیامدها و هزینه های زیست محیطی آن را درک نمایند.The Measurement of Environmental Resilience In the District 14 of Tehran
Today, environmental issues have become one of the most important challenges for urban planners, and unbridled urban development has added to their complexity. Resiliency approach planning can, in all respects, create the capacity to deal with the turbulent future. The purpose of this study was to evaluate the environmental resilience of neighborhoods in the district 14 of Tehran. In principle, 23 neighborhoods have been investigated by selecting five environmental indicators. The five indicators were ranked by 30 urban planning experts through hierarchical analyzes of AHP, and then the Gray Relationship Analysis of the status and location of neighborhoods in the district 14 were analyzed concerning each indicator. Finally, the normal line of 0.714 was drawn as the final score in all indices, indicating that 12 neighborhoods had a low resilience. Based on the obtained results, the environmental resilience is reduced while moving towards the western and southwest neighborhoods,. This is in harmony with the texture and population density of the region. Therefore, urban planners need to understand the consequences and environmental costs of physical development rather than physical development itself.
