سنجش و اولویت بندی شاخص های شهر اکولوژیک در توسعه شهری با مدل یابی معادلات ساختاری (sem ) (مورد مطالعه: شهر بندرعباس)

بیان مسئله: امروزه برنامه ریزی با تاکید بر بعد اکولوژیکی رکن جدایی ناپذیر توسعه پایدار شهری محسوب می شود که طی آن توسعه شهری مبتنی بر رویکرد اکولوژیک از طریق کاهش اثرات زیست محیطی فعالیت های اقتصادی و بیشینه کردن روابط اجتماعی به دنبال رسیدن به شهر سالم است. این پژوهش با ماهیت توسعه ای کاربردی و از نوع توصیفی تحلیلی با سنجش شاخص های شهر اکولوژیک در توسعه شهری به اولویت بندی و مدل‌یابی ابعاد موثر بر توسعه شهری اکولوژیک در بندرعباس پرداخته است.‌ مطابق با نتایج تحلیل، شاخص منظر و چشم انداز شهری و سلامت شهری به عنوان متغیر مستقل به ترتیب با بار عاملی 0.94 و 0.88 بیشترین تاثیر و شاخص آلودگی فضای شهری نیز با 0.47 کمترین میزان اهمیت را بر روی سازه توسعه شهری اکولوژیک به عنوان متغیر وابسته دارند. همچنین شاخص نفوذ در طبیعت و محیط با ضریب 0.79، حمل و نقل پایدار با ضریب 0.75، حس تعلق به مکان با ضریب 0.74 به ترتیب جایگاه های سوم تا پنجم را دارند. متغیر مشارکت اجتماعی و دسترسی به خدمات شهری نیز به ترتیب با ضریب 0.63 و 0.51 در رتبه ششم و هفتم قرار دارند. مقادیر آمارهای مستخرج از مدل نظری تحقیق نیز همگی حاکی از انطباق خوب و مناسب مدل است و گویه های انتخاب شده برای سنجش الگوی توسعه بندرعباس مبتنی بر رویکرد شهر اکولوژیک از اعتبار لازم برخوردار بوده و به خوبی می توانند سازه/مولفه های هشتگانه تحقیق را مورد سنجش قرار دهند.اکولوژیگ از اعتبار لازم برخوردار بوده و به خوبی می توانند سازه/مولفه های هشتگانه تحقیق را مورد سنجش قرار دهند.

measuring and prioritizing ecological city indicators in urban development by structural equation modeling (sem) (case study: bandar abbas city)

introduction: the concept of ecological city originates from the fundamental goal ofsustainability and the application of environmental principles in urban planning,design, and management. today, planning with emphasis on the ecological dimensionis an integral pillar of sustainable urban development, during which urbandevelopment based on an ecological approach seeks to achieve a healthy city byreducing the environmental impact of economic activities and maximizing socialrelations. bandar abbas, as the most populated coastal city in the south of the countryand the largest port in iran, has been one of the places that attract people on a nationalscale, which has seen a lot of development in recent years due to the creation ofeconomic opportunities. the location of this city among the ecologically protectedareas such as coastal wetlands and on the other hand its rapid physical developmentwithout environmental considerations along with the rapid development of pollutingindustries in the west of this city, the increase in relative population density, and thesignificant reduction of green space per capita have caused serious problems.therefore, examining the status of ecological city indicators in bandar abbas andidentifying the key drivers, and presenting the ecological city development modelbased on a planning model is the main goal of this research.objectives: measuring the state of urban development of bandar abbas based onecological city indicators is the main goal of this article. this can help to achieve asuitable ecological development model for this important coastal city.method: this research has descriptive analytical nature with a descriptive analyticalnature by measuring the indicators of the ecological city in urban development andhas prioritized and modeled the dimensions affecting the ecological urbandevelopment in bandar abbas. for this reason, the questionnaire method, anddescriptive and inferential statistical methods and the delphi technique have beenused in this research. in the study, eight identified indicators of the ecological city havebeen used. these indicators include urban landscape, urban health, urban pollution,influence on nature and environment, sustainable urban transportation, sense ofbelonging to a place, social participation, and urban services. these indicators have been measured in the form of 38 items according to likert's five point scale in theform of a designed questionnaire.result: according to the results of the analysis, the index of urban landscape andurban health as independent variables with a factor load of 94.0 and 88.0,respectively, the most impact, and the index of urban space pollution with 47.0 theleast importance on the structure of urban ecological development as a dependentvariable. also, the index of influence on nature and environment with a coefficient of79.0, sustainable transportation with a coefficient of 75.0, and sense of belonging witha coefficient of 74.0 have the third to fifth positions, respectively. the variables ofsocial participation and access to urban services are also ranked sixth and seventhwith a coefficient of 63.0 and 51.0, respectively. in addition, the obtained results showthat despite the common theory of urban development, ecological environmental andsocial institutional components are more important than physical spatial componentsin urban development in bandar abbas city. in general, the statistical analysis carriedout shows that the items selected to measure the development pattern of bandarabbas based on the ecological city approach have the necessary validity and canmeasure the eight components of the research.
