چکیده | ||
شهرها، نظامهای پیچیدهای هستند که نسبت به تهدیدهای طبیعی یا انسانی آسیبپذیرند. نگاهی که تاکنون در مدیریت سوانح و مدیریت شهری وجود داشته، رویکرد کاهش مخاطرات بوده است. اما امروزه جوامع در تلاش براى دستیابی به شرایطی هستند که در صورت وقوع بحران، بازگشت سریع آنها را به وضعیت پیش از بحران (اولیه و عادی) فراهم سازد. در این میان تابآوری، مفهوم جدیدی است که بیشتر در مواجهه با ناشناختهها و عدم قطعیتها به کار میرود. هدف کلی مطالعه حاضر، ارزیابی میزان تابآوری شهر پلدختر به هنگام وقوع سیل است. در راستای دستیابی به اهداف مذکور از روش کیفی با رویکرد توصیفی-تحلیلی استفادهشده است. بهمنظور سنجش ابعاد تابآوری در محلات شهر پلدختر ۳۸۴ خانوار با استفاده از فرمول کوکران بهعنوان جامعه نمونه انتخاب گردیدند. بهمنظور تجزیه و تحلیل دادههای حاصل از پرسشنامه در محیط نرم افزار SPSS ، روشهای آماری مبتنی بر مقایسه میانگینها، آزمونهای فریدمن و رگرسیون به کار گرفته شد و نیز جهت رتبهبندی تابآوری محلات از مدل تاپسیس استفاده گردید. در نتیجه براساس پنج شاخص ارزیابی تابآوری؛ محلههای کوی بسیجیان، هسته قدیم و کوی پاسداران نسبت به سایر محلات شهر پلدختر دارای وضعیت مناسبتری هستند و محلههای ساحل شرقی و غربی و کوی سازمانیها از بدترین وضعیت را به لحاظ تابآوری در مقابل سیل برخوردارند. نتایج حاصل از آزمون فریدمن برای تعیین مهمترین و تأثیرگذارترین شاخصها تابآوری شهر پلدخترگویای این است که شاخص کالبدی با میانگین رتبه 533/3 و شاخص اقتصادی با میانگین رتبه 251/3 به ترتیب در رتبههای اول و دوم اثرگذارترین و مهمترین ابعاد تابآوری قرارگرفتهاند. | ||

چکیده [English] | ||
Cities are complex systems that are vulnerable to natural or human threats. The current dominant view in disaster and urban management has been the risk reduction approach. However, today, societies are trying to achieve conditions that will allow them to quickly return to the pre-crisis (initial and normal) state in the event of a crisis. Resilience is a new concept that is mostly used in dealing with unknowns and uncertainties. The overall goal of the present study is to evaluate the level of resilience of the city of Pol-e Dokhtar during a flood. In order to achieve the aforementioned goals, a qualitative method with a descriptive-analytical approach was used. In order to measure the dimensions of resilience in the neighborhoods of Pol-e Dokhtar, 384 households were selected as a sample community using the Cochran formula. In order to analyze the data obtained from the questionnaire in the SPSS software environment, statistical methods based on comparison of means, Friedman tests and regression were used. The TOPSIS model was used to rank the resilience of the neighborhoods. As a result, based on five resilience assessment indicators; the Basijian, Old Core (Hasteh Ghadimi) and Pasdaran neighborhoods have a more favorable situation than other neighborhoods in Pol-e-Dokhtar city. The East and West Coast neighborhoods (Sahel Sharghi va Gharbi) and Sazmaniha neighborhoods have the worst situation in terms of resilience against floods. The results of the Friedman test to determine the most important and influential resilience indicators of Pol-e-Dokhtar city showed that the physical index with an average of 3.533 and the economic index with an average of 3.251 were ranked first and second, respectively. | ||
