سنجش تاب آوری زیست محیطی در سطح محلات منطقه چھارده شھر تھران

امروزه مسائل زیست محیطی به یکی از مهمترین چالش‌های برنامه‌ریزان شهری تبدیل شده است و توسعه لجام گسیخته شهری بر پیچیدگی آن افزوده است. برنامه‌ریزی با رویکرد تاب‌آوری می‌تواند در تمامی ابعاد، ظرفیت‌های لازم برای مقابله با آینده آشفته را ایجاد نماید. هدف این مطالعه، ارزیابی تاب‌آوری زیست محیطی محلات منطقه چهارده شهر تهران می‌باشد. در اصل 23 محله با انتخاب 5 شاخص زیست محیطی مورد بررسی قرار گرفته است. پنج شاخص مذکور توسط 30 نفر از خبرگان برنامه‌ریزی شهری از طریق تحلیل سلسله مراتبی ahp رتبه‌بندی 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 شاخص‌ها ترسیم گردید که نشان می‌دهد 12 محله، از تاب‌آوری پایینی برخوردارند. با توجه به نتایج بدست آمده هرچه به سوی محلات غربی و جنوب غربی حرکت می‌کنیم، از میزان تاب‌آوری زیست محیطی کاسته می‌شود. این موضوع کاملاً با بافت فرسوده و تراکم جمعیتی منطقه هماهنگ است. بنابراین لازم است برنامه‌ریزان شهری بیش از اینکه بر توسعه فیزیکی تاکید نمایند، پیامدها و هزینه‌های 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.
