چکیده

سابقه و هدف:
امروزه بافت‌های فرسوده یک معضل بزرگ در شهرها هستند که قانونگذار برای حمایت از آن، قوانین و مقرراتی را وضع کرده ولی متاسفانه علی­رغم سالیان سال نوسازی، وجود نواقص و کاستی­های قانونی سبب شده اهداف مورد نظر به طور کامل تحقق نیابد. با توجه به اهمیت موضوع بهسازی و نوسازی شهری به عنوان راهبردی در راستای کاهش مشکلات بافت‌های شهری مطرح می باشد که یکی از رویکردهای نوین در این زمینه مقوله بازافرینی است. باز آفرینی شهری رویکردی نوین در مواجهه با پدیده فرسودگی است که تسهیل کننده تجدید حیات اجتماعی و اقتصادی، در کنار احیای کالبدی بافت است. هدف از تحقیق حاضر تعیین و سنجش اولویت ابعاد بازآفرینی بافت­های فرسوده جهت برنامه­ریزی قانونی است.
مواد و روش­ها:
تحقیق حاضر به لحاظ هدف در زمره تحقیقات بنیادی قرار دارد و  روش انجام آن به طور توام از روش های کیفی و کمی می باشد. در بخش کیفی از رویکرد گراندد تئوری [1]انجام شده است . جهت تحلیل مطالعات اسنادی از روش فراترکیب و تحلیل محتوا استفاده شده است. جامعه آماری این پژوهش شامل افراد متخصص و صاحبنظر و اساتید دانشگاه در رشته طراحی و برنامه ریزی شهری می باشند.روش جمع آوری اطلاعات مطالعه اسنادی ، دیدگاه ها ، تعاریف و مصاحبه عمیق و باز است. در این مطالعه با توجه به محدود بودن جامعه آماری محدود متخصص با 35 نفر مصاحبه انجام شد . جهت تحلیل داده های کیفی  و کدگذاری و بررسی میزان فراوانی کدهای مستخرج از مصاحبه از نرم افزار NVivo استفاده شد. در ادامه جهت تعیین الویت بندی از روش AHP و نرم­افزار Expert Choice  و پرسشنامه مقایسات زوجی استفاده شده است. در این راستا، نمونه موردی که ارزش­گذاری معیارها براساس مشکلات آن محدوده تعیین گردید، محله سیروس؛ بدلیل قرار داشتن در هسته تاریخی شهر تهران و نیز با توجه به انتخاب محله بعنوان پایلوت اجرای اهداف بازآفرینی در سال 97، در نظر گرفته شد.
نتایج و بحث:
مولفه های " بازآفرینی کالبدی" ، " بازآفرینی اجتماعی"، " بازآفرینی زیست محیطی"، " بازآفرینی مدیریت شهری" و " بازآفرینی اقتصادی " به عنوان مولفه­های قانونی ارتقای تاب آوری در فرآیند بازآفرینی بافت فرسوده مستخرج از تحلیل کیفی بدست آمد که در این میان با توجه به مشکلات اجتماعی و تاثیرگذاری جامعه در محله سیروس، نتایج تحلیل فرآیند سلسله مراتبی با مشکلات فعلی نشان داد شرط تحقق­پذیری اهداف بازآفرینی در بافت تاریخی در گرو پیوند این محله با سایر شهر تهران و ساکنان است. بهبود وضعیت اجتماعی در محله­ای برخوردار از حس تعلق بالا، با بهبود شاخص­های اجتماعی، افزایش میزان کیفیت سکونت و حس رضایتمندی، جلوگیری از فرآیند مهاجرت از محله و در نهایت بهبود بستر توسعه محقق خواهد شد. از سوی دیگر با توجه به اهمیت مدیریت شهری در توسعه شهری، رویکرد کل­نگر، فراگیر و یکپارچه مدیریت با توجه به ابعاد اجتماعی - اقتصادی ساکنان و جلوگیری از اقدامات جزئی در بخش مسکن، تحقق­پذیری اهداف مورد نظر در بازآفرینی جهت ارتقای تاب آوری را تسهیل می­کند.
نتیجه­ گیری:
نتایج حاصل شده گویای این امر است که برنامه­ریزی جهت بهبود شاخص­های اجتماعی می­باید در اولویت اول قانونگذاری قرار گیرد تا بهبود بستر توسعه، تحقق اهداف بازآفرینی  را تسهیل کند.  [1] Grounded theory

چکیده [English]

Introduction: Today, urban decay is a grave problem in metropolises. Despite the rules and regulations passed by the lawmakers to protect areas affected by the phenomenon, and in the face of all years-long regeneration, faults and flaws in the laws have hindered the perfect implementation of the desired objectives. Given the importance of the issue, urban renovation and reconstruction are the strategies adopted to resolve the problems of the urban fabric. A novel approach in tackling the problem, regeneration facilitates the social and economic revival as well as spatial restoration of the fabric. The aim of the present study is to identify and prioritize various aspects of regeneration of the urban decay for the purpose of legal planning.
Material and methods:
The present study is classified as a basic research in terms of the objective, and qualitative and quantitative methods were used to conduct it. Grounded Theory was the approach selected for the qualitative part, while the documentary research was carried out using content analysis and meta synthesis. The research population is comprised of experts, scholars, and university professors in urban planning. Data were collected through documentary research, opinions, definitions, and in-depth open-ended interviews. A total of 35 individuals were interviewed for the purpose of this research. Qualitative data analysis, coding, and identifying the frequency of the codes extracted from interviews were done using NVivo. Then, the heirarchies were decided using AHP method and Expert Choice progra along with paired comparison questionarre. To this, Sirus Neighborhood in Tehran was selected as the case study according to the valuation of criteria based on the issues the neighborhood is faced with. Another reason for this choice was that it had been selected as the pilot location to carry out the regeneration objectives.
Conclusions and discussion:
"Physical regeneration”, "social regeneration”, "environmental regeneration”, "urban managemnet regeneration”, and "economic regeneration” were extracted from the qualitative analysis as the legal components of resilience in the process of urban decay regeneration. Meanwhile, considering social complications and the influence of the community on the neighborhood indicated that establishing ties between the neighborhood in question and other neighborhoods of Tehran and their residents is the prerequisite to the realization of regeneration objectives in the historical area. Improving the social condition in the neighborhoods with greater sense of attachment can be materialized through the improvement of social indicators, increase in the quality of life and sense of satisfaction, preventing immigration, and eventually, providing better development platforms. Meanwhile, given the importance of urban management in urban development, a holistic, integrated, and inclusive approach which draws upon social and financial condition of the residents and preventing trivial actions in housing sector can help to achieve the regeneration objectives in the improvement of resilience.
Conclusion:
The findings indicate that planning to improve social indicators must be the highest priority of lawmakers in order that the improvement in development platform can facilitate the realization of regeneration objectives.
