مدل سازی ساختاری نقش شاخص های اقتصادی بر تاب آوری کالبدی زیرساختی در برابر روانآب های سطحی (مطالعه موردی: منطقه 7 شهر اهواز)

موضوع تاب‌آوری هم از لحاظ علمی و نظری و هم از لحاظ کاربردی و عملی در جهان اهمیت بسیاری یافته است. مفهوم تاب‌آوری شهری نیز شامل روش‌هایی می‌شود که در آن شهر‌ها با تغییر روبرو هستند و ظرفیت افراد، جوامع، موسسات، مشاغل و سیستم‌های درون یک شهر جهت رویارویی و پاسخگویی با انواع فشار‌ها، افزایش می‌یابد. امروزه نگاه جهانی به مخاطرات از تمرکز بر کاهش آسیب‌پذیری به افزایش تاب‌آوری تغییر کرده است. در نتیجه کاربرد مفهوم جوامع تاب‌آور و راه‌های ایجاد و تقویت آن‌ها کاربرد بیشتری یافته است؛ در این راستا این پژوهش کاربردی با استفاده از روش تحلیلی _توصیفی با هدف یافتن نقش شاخص‌های اقتصادی بر تاب‌آوری کالبدی _زیرساختی در برابر رواناب‌های منطقه 7 شهرداری شهر اهواز تدوین گردیده است. جامعه آماری این پژوهش را ساکنین این منطقه تشکیل می‌دهد و جهت تعیین حجم نمونه با استفاده از فرمول کوکران تعداد 382 پرسشنامه بین افراد این منطقه توزیع شد. پایایی ابزار تحقیق به وسیله آلفای کرونباخ تایید شد که عدد آن برابر با 0.852 می‌باشد. به منظور تجزیه و تحلیل نتایج حاصل از پرسشنامه از آزمون‌های آماری و مدل‌سازی معادلات ساختاری در محیط نرم‌افزار‌های spss   و amos انجام شد؛ سطح معناداری 0.189 در معیار کالبدی و 0.040 در معیار اقتصادی نشان‌دهنده تاب‌آوری ضعیف هرکدام از این معیار‌ها بصورت جداگانه می‌باشد و همچنین نتایج این پژوهش در مدلسازی ساختاری نشان می‌دهد که شاخص‌های اقتصادی نقش بسزایی در تاب‌آوری کالبدی _زیرساختی دارد و نامطلوب بودن شاخص‌های اقتصادی، تاب‌آوری کالبدی_زیرساختی منطقه را بشدت کاهش می‌دهد و از طرفی موجب افزایش ریسک آسیب‌پذیری منطقه 7 شهرداری اهواز می‌گردد.

structural modeling of the role of economic indicators on physical-infrastructural resilience of surface runoff (case study: district 7 of ahvaz)

the issue of resilience has become very important both scientifically and theoretically, as well as in practice and practice in the world. the concept of urban resilience also includes the ways in which cities change and the capacity of individuals, communities, institutions, businesses, and systems within a city to cope with and respond to a variety of pressures. today, the global view of risk has shifted from a focus on reducing vulnerability to increasing resilience. as a result, the application of the concept of resilient societies and the ways to create and strengthen them have become more widely used; in this regard, this applied research has been compiled using analytical descriptive method with the aim of finding the role of economic indicators on physical infrastructure resilience against runoff in district 7 of ahvaz municipality. the statistical population of this study consists of residents of this region and to determine the sample size using cochran’s formula, 382 questionnaires were distributed among the people of this region. the reliability of the research instrument was confirmed by cronbach’s alpha, which is equal to 0.852. in order to analyze the results of the questionnaire from statistical tests and structural equation modeling in spss and amos software environment; significance level of 0.189 in physical criterion and 0.040 in economic criterion indicates poor resilience of each of these criteria separately and also the results of this study in structural modeling show that economic indicators play a significant role in has physical infrastructure resilience and the unfavorable economic indicators, the physical resilience infrastructure resilience of the region greatly reduces and on the other hand increases the risk of vulnerability in district 7 of ahvaz municipality.extended abstract introductionin the early years of the 21st century. it happened in human life that these changes in the context of globalization have affected the economy, culture, social relations and human life and reflected these relations in the spatial formation, especially in cities, which are in fact part of the institutions. are dynamic society, manifested. according to the united nations, more than half of the world’s population now lives in cities, which by 2030 will reach 60%. on the other hand, increasing migration to cities has posed a wide variety of challenges to urban development. at present, the issue of resilience has become very important in the world, both scientifically and theoretically, as well as in practice and practice, and has provided a new perspective on complex social, environmental and sustainable development systems. resistance, especially the concept of urban resilience, includes the way in which cities change and the capacity of individuals, communities, institutions, businesses, and systems within a city to respond and adapt to a variety of pressures. today, the global view of risk has shifted from focusing on reducing vulnerability to increasing resilience. as a result, the application of the concept of resilient societies and the ways to create and strengthen them have become more widely used. different individuals and schools, according to their views and approaches, have paid attention to the issue of resilience in the field of economics and have organized their studies accordingly. it is a resilient economic system when it can absorb temporary or permanent shocks and adapt to rapidly changing conditions without losing its stability. among the dimensions of resilience, the economic dimension is basically one of the most important; according to recent discussions in urban planning and related economics, measuring economic structures is possible by identifying the weaknesses of the economic system in order to increase economic resilience caused by human and natural disasters. water and sewage supply and water services in general are essential needs for human well being. however, in many countries these services are not performed and organized in a planned and controlled manner. especially in urban areas where systems are exposed to internal or external disturbances and may cause serious problems for the health and environment of individuals as well as the economy of communities. methodologythis research is applied in terms of purpose and in the research literature section, library method and field studies have been used to collect information. so that the required information in the research literature section is obtained through documentary and library studies and research background, and in the next stage, the available data and information through the study of comprehensive plans and plans of the ahvaz municipality improvement and renovation organization in order to identify the study area was collected, and field studies were collected through a researcher made questionnaire. the statistical population of this study is the residents of district seven of ahvaz municipality. cochran’s formula was used to determine the sample size and in order to process information to analyze the resilience of the region in the study area, structural equation modeling methods and statistical analysis methods such as spss and amos software were used.
