چکیده مقاله :
زمینه و هدف: در دهه های اخیر بلایای رخ‌داده نظیر زلزله در ایران حاکی از این موضوع است که جوامع انسانی و اقتصادهای محلی بیشتر به خطر افتاده‌اند و ریسک‌ها نیز افزایش‌یافته است. لذا شهرها به‌عنوان بستر وقوع حوادث داراي اهمیت زيادي مي باشند، که به این منظور ارتقاء تاب‌آوری پس از زلزله در نقاط شهری از اهمیت زیادی برخوردار است. منطقه 1 شهر تهران با توجه به قرارگیری بر روی گسل و همچنین چالش‌های شهری گسترده امروزه یکی از جوامع آسیب‌پذیر در برابر زلزله است که بر این اساس ناحیه 7 آن به دلیل تمرکز ساختمان‌های بلندمرتبه،کمبود فضاهای باز و مشکلات مدیریت بحران بیش از سایر نواحی آن با چالش‌های تاب‌آوری مواجهند.
روش بررسی: هدف از پژوهش حاضر سنجش آسیب‌پذیری محله‌های ناحیه 7 در برابر زلزله با رویکرد تاب‌آوری است. این پژوهش با توجه به هدف از نوع کاربردی و درزمینه نحوه گردآوری داده ها از نوع پیمایشی و در رابطه با ماهیت داده ها از نوع پژوهش های کمی است.ابزار اصلی گردآوری داده‌های میدانی پژوهش، پرسشنامه تاپسیس می‌باشد کـه برپایـه پیشـینه پژوهش و مطالعات مقدماتی پژوهشگران درزمینه هماهنگ کردن پرسشنامه اصلی با شـرایط و مقتضیات خدمات مدیریت محلی تنظیم شده است.جامعه آماری تحقیق را کلیه کارشناسان و متخصصان حوزه مدیریت بحران و برنامه‌ریزی شهری تشکیل می دهند که حجم نمونه آن بر اساس فرمول کوکران تعداد 40 نفر تخمین زده شد
یافته ها:پژوهش حاضر با استفاده از آزمون میانگین در نرم افزار spss و در راستای سنجش میزان تاب‌آوری در محله‌ها از روش تصمیم‌گیری چند شاخصه تاپسیس در نرم افزار matlab استفاده‌شده است .
بحث و نتیجه گیری: نتایج نشان داد بیشترین میزان چالش در تاب‌آوری شهری ناحیه 7 مربوط به تاب‌آوری نهادی و محیطی-کالبدی می‌باشد و هر سه محله تجریش ، باغ فردوس و قیطریه از مقادیر کمتری درزمینه شاخص‌های تاب‌آوری شهری در برابر زلزله برخوردارند که در این میان تجریش با 0.73 از میزان تاب‌آوری مناسب‌تری نسبت به باغ فردوس و سپس قیطریه برخوردار است.
Background and Objective: In recent decades, natural disasters such as earthquakes in Iran indicate that human societies and local economies are more at risk and vulnerabilities have increased. Therefore, cities play a vital role as the scene of incidents, making enhancing post-earthquake resilience in urban areas very important. Region 1 of Tehran city, due to its location on a fault line and extensive urban challenges, is considered one of the vulnerable communities to earthquakes. Consequently, region 7 faces more resilience challenges due to the concentration of high-rise buildings, lack of open spaces, and crisis management issues compared to other areas.
Material and Methodology: The aim of this research is to assess the vulnerability of neighborhoods in region 7 to earthquakes with a focus on resilience. This study is considered applied research in terms of data collection method, which is survey-based, and falls under quantitative research in terms of data nature. The primary tool for collecting field data in this research is the TOPSIS questionnaire, tailored based on previous research and preliminary studies to align the questionnaire with the conditions and requirements of local government services. The statistical population of the research consists of all experts in the field of crisis management and urban planning, with a sample size estimated at 40 individuals based on the Cochran formula.
Findings: The current study utilized the average test in SPSS software and the TOPSIS multi-criteria decision-making method in MATLAB software to assess the level of resilience in neighborhoods.
Discussion and Conclusions: The results indicated that the highest challenges in urban resilience in region 7 are related to institutional and environmental-physical resilience. The neighborhoods of Tajrish, Bagh Ferdows, and Gheytarieh exhibit lower values in terms of urban resilience indicators against earthquakes. Among them, Tajrish demonstrates a higher level of resilience at 0.73 compared to Bagh Ferdows and then Gheytarieh.
