چکیده مقاله :
زمینه و هدف: سیلاب از جمله مخاطرات طبیعی محسوب می‌شود که علاوه بر عوامل طبیعی تا حدودی تحت تأثیر عوامل انسانی نیز می‌باشد و اجتماعات روستایی به دلیل ارتباط عمیقی که با محیط و فعالیت‌های کشاورزی دارند بیش‌تر از سایر گروه‌های انسانی تحت تأثیر آسیب‌های ناشی از مخاطره سیلاب میباشند. بر این اساس در سطوح مختلف مدیریت سوانح شرایط مطلوبی برای کاهش کارآمد و موثرتر خطرها ایجاد شده است. در این میان تاب آوری و افزایش آن در ابعاد مختلف به عنوان یکی از مهم‌ترین عوامل تحقق پایداری و عامل مکمل در فرایند مدیریت بحران در نظر گرفته شده است. پژوهش حاضر با هدف تحلیل جامع تاب‌آوری شهری در برابر مخاطرات با استفاده از تحلیل عاملی در شهر سنندج انجام گرفته است.
روش بررسی : این پژوهش از نظر روش در زمره تحقیقات توصیفی- تحلیلی و از نوع همبستگی محسـوب مـي‌شود. مطالعه حاضر در دو بخش تفسیر و گزارش شده است. در بخش اول، به بررسی روایی سازه پرسشنامه طراحی شده عوامل موثر در تاب‌اوری شهر سنندج پرداخته شده است. روایی سازه از طریق دو روش تحلیل عاملی اکتشافی و تحلیل عاملی تأییدی انجام شده است و جهت بررسی تغییرناپذیری پرسشنامه طراحی شده در شهر سنندج از روش چند گروهی استفاده گردیده است. بخش دوم، بررسی تحلیل و مقایسه شاخص‌ها و ارتباط هر یک از آن‌ها براساس روش های توصیفی و استنباطی و معادلات ساختاری بود.
یافته ها: در تحلیل عامل تأییدی مرتبه اول، مقادیر شاخصهای برازندگی نشان دهنده برازش قابل قبول الگوی پیشنهادی با دادهها میباشند.
بحث و نتیجه گیری: با توجه به نتایج سازۀ ضرایب استاندارد، بیشترین ضریب در مؤلفه‌ها به شاخص کالبدی اختصاص داده شده است و همچنین نتایج نشان می‌دهد تاب‌آوری شهر سنندج دارای روایی همگرا و واگرای مناسب می‌باشد.
Background and Objectives: flood is considered as one of the natural hazards, which in addition to natural factors is also influenced to some extent by human factors, and rural communities are more affected by flood hazards than other human groups due to their deep connection with the environment and agricultural activities. Are. Based on this, at different levels of accident management, favorable conditions have been created for efficient and effective reduction of risks. In the meantime, resilience and its increase in different dimensions is considered as one of the most important factors for realizing sustainability and a complementary factor in the crisis management process. The current research was conducted with the aim of comprehensive analysis of urban resilience against hazards using factor analysis in Sanandaj city.
Material and Methodology: The present study falls within the category of applied studies and can be recognized as a descriptive-analytical study and a correlational factor analysis in terms of methodology. The sample size was estimated to be 395 (p=5%) and the questionnaires were distributed among samples through simple random distribution.
In terms of method, this research is considered as a descriptive-analytical and correlational type of research. The present study is interpreted and reported in two parts. In the first part, the structural validity of the designed questionnaire on the factors affecting the resilience of Sanandaj city has been investigated. Construct validity was done through two methods of exploratory factor analysis and confirmatory factor analysis, and multi-group method was used to check the invariability of the questionnaire designed in Sanandaj city. The second part was to examine the analysis and comparison of indicators and the relationship of each of them based on descriptive and inferential methods of Dimtel and structural equations. SPSS26 software was used to investigate the exploratory factor analysis and statistical tests related to the research hypotheses, AMOS24 software was used for the first and second order confirmatory factor analysis, and AMOS24 software was used to check McDonald's omega coefficients.
Findings: In the first-order confirmatory factor analysis, the values of the goodness-of-fit indices show the acceptable fit of the proposed model with the data.
Discussion and conclusion: According to the results of the structure of standard coefficients, the highest coefficient in the components is assigned to the physical index, and also the results show that the resilience of Sanandaj city has appropriate convergent and divergent validity.
