چکیده:
فرم شهرها در ایران به خصوص کلانشهرها به صورت پراکنده گسترش یافته است. اما شهرسازی سنتی در ایران همواره با توجه به ساختار فضایی فشرده در ارتباط با زمینه خود (جغرافیا، فرهنگ) شکل میگرفته است. فشردگی در فرم و ساختار فضایی شهری مفهومی است که برای سازماندهی شهرها از حالت آشفتگی و پراکندگی مطرح میشود و بهطور گسترده در برنامهریزی و توسعه شهری پایدار، شهر فشرده را تفسیری عمیق از آنچه که یک شهر پایدار باید باشد، میدانند. هدف اصلی پژوهش، سنجش پذیرش اجتماعی شهر فشرده در شهر اهواز میباشد. تحقیق از نظر هدف، کاربردی، از نظر روش توصیفی –تحلیلی است. با بررسی مطالعات مرتبط شاخصهای تحقیق در دو بخش شهر فشرده و توسعه پایدار شهری تدوین گردید. جامعه آماری اول شهروندان شهر اهواز میباشند که با توجه جمعیت شهر اهواز با استفاده از فرمول کوکران 384 نفر به عنوان حجم نمونه انتخاب گردید. جامعه آماری دوم شامل متخصصان مدیران و کارشناسان برنامهریزی شهری شهر اهواز میباشد که با استفاده از نمونهگیری هدفمند 30 نفر بهعنوان حجم نمونه انتخابشده است. به منظور تحلیل دادهها از مدلسازی معادلات ساختاری در نرمافزارهای Amos و Smart-pls استفاده گردید. نتایج حاکی از این است شاخصهای شهر فشرده شامل تراکم، تنوع، تشدید و حملونقل عمومی بر شاخصهای توسعه پایدار شهری شامل محیطی، اقتصادی و اجتماعی در شهر اهواز تأثیر مثبت و معنیداری دارند. بنابراین شهروندان و مدیران بهرهگیری از شهر فشرده را بسترساز تحقق توسعه پایدار شهری در شهر اهواز میدانند.
Structural modeling measurement the social acceptability of compact city (case study: Ahvaz city)AbstractIntroductionThe form of cities in Iran, especially in metropolitan areas, is sprawl. But traditional urban planning in Iran has always been shaped by the compact spatial structure associated with its context (geography, culture). Compactness in urban form and structure is a concept that is used to organize cities from a state of confusion and dispersion and broadly in sustainable urban planning and development, the compact city is seen as a profound interpretation of what a sustainable city should be. In studies related to compact cities, one of the topics that has been considered is the discussion of the acceptability and feasibility of compact cities. Social acceptability is an important factor in feasibility. Due to the importance of studying the acceptability and feasibility of urban forms, especially the compact form from the perspective of the public and residents and due to the lack of investigation of the impact of the compact city on the realization of sustainable urban development This research investigates the social acceptability of compact city in Ahvaz.MethodologyThe present research is applied in terms of purpose which is in the category of descriptive survey research. In terms of philosophy, this research is a deductive research that is based on the paradigm of positivism and quantitative approach and is considered as a cross-sectional research in terms of time index. The data collection tool in the present study is a questionnaire. Thus, to measure the theory of the compact city, four indicators including density, diversity, intensification and transportation and the theory of sustainable urban development, three environmental, economic and social dimensions have been used. The Likert scale was used to answer the questions and the numbers 1 to 5 were used to score the answers. The questionnaire was completed by two groups of citizens, experts and managers. The statistical population is the first group of citizens of Ahvaz who were selected as a sample using Cochran's formula 384 people. And the second statistical population is experts and managers of Ahvaz city, which was purposefully selected 30. The structural equations method in Amos was used to analyze the citizen-related questionnaire and the structural equations in Smart-pls software were used to analyze the questionnaire of experts and managers.Discussion and ResultsCompact city assessment in previous studies has been done retrospectively with methods such as survey method, objective data and interview. In this research, a survey method has been used to investigate the feasibility and social acceptance capacity of the compact city and its impact on sustainable urban development in the city of Ahvaz. The variables and indexes that have been selected for the economic, social and environmental dimensions of sustainable urban development are most evident in the city of Ahvaz, and these indicators are the consequences of sprawl growth and unsustainable development of the city in recent decades. Since the compact city has been proposed as a suitable solution in sprawl studies and urban sustainability, the indicators of the compact city have been selected as an independent variable. From the citizens' point of view, the highest coefficient of the route is related to the effect of transportation on the environmental variable, after that, the effect of the diversity variable on the economic variable has the highest coefficient. The impact coefficients of all hypotheses are higher than 0.60. The results of the experts' research indicate that the effect of density variable on three environmental, economic and social indicators is 0.870, 0.890 and 0.900, respectively. The coefficient of diversity path on environmental, economic and social indicators has been calculated as 0.830, 0.865 and 0.864, respectively. The intensification variable with path coefficients of 0.810, 0.853 and 0.872 has a significant effect on environmental, economic and social indicators, respectively. The coefficients of the variable of transportation on environmental, economic and social indicators are 0.790, 0.837 and 0.880.ConclusionThe results indicate that the indicators of the compact city including density, diversity, intensification and public transport have a positive and significant effect on the indicators of sustainable urban development including environmental, economic and social in Ahvaz city. Therefore, citizens and managers consider the use of the compact city as the basis for the realization of sustainable urban development in Ahvaz.In addition to the fact that all indicators of the compact city must be implemented at the same time, it is necessary to pay attention to the issue of spatial planning and migration control in Khuzestan province and Ahvaz city in order to reduce problems and obstacles in its implementation.Keywords: urban form, compact city, sustainable urban development, Ahvaz, structural modeling.
خلاصه ماشینی:
در سه دهه اخیر بسیاری از پژوهش ها به بررسی و تبیین نظریه شهر فشرده پرداخته اند و تأثیر آن بر شاخص های پایداری و توسعه پایدار شهری( Williams et ;١٩٩٩ Newman and Kenworthy ;٢٠٠٢ Burton ;٢٠٠٥ ,Arbury al, 2000; Gaigné et al,2012; Gugger & Kerschbaumer,2013; Stevenson et al,2016; Lee ٢٠٢٠,Shirazi ;٢٠١٨,Lim &).
پژوهش هایی که به بررسی تأثیر شهر فشرده بر توسعه پایدار شهری پرداخته اند شهرها و مناطقی (مانند هنگ گنگ ، اندونزی، هند، سوئد، تایلند) را مورد بررسی قرار داده اند که دارای فشردگی و تراکم بالا بوده اند و درواقع تعدادی از شاخص های شهر فشرده در این شهرها اتفاق افتاده است و پژوهشگران به صورت عینی و تجربی تأثیرات فشردگی را مورد بررسی قرار داده اند(؛ Roychansyah & Eng,2005; Coorey et al,2005; Lin & ang,2006; Chen et al,2008; ٢٠٢٠,Bibri;٢٠١٦,Saniroychansyah et al ;٢٠١٥,Bardhan et al ;٢٠١٢,Kotharkar et al؛).
سوء مدیریت شهری و منطقه ای و تفاوت در ساماندهی فضاهای شهری جهت تخصیص امکانات و خدمات رفاهی با تمرکز امکانات زیرساختی و رفاهی در نقاط خاص و نادیده انگاشتن بعضی از فضاهای شهری، باعث شد که محلات و مناطق 1 -Bramley 2 - Williams 3 - Shirazi & Falahat 4- Breheny 5 - Mohammadi Doost 6 - Ali Akbari شهری اهواز لحاظ توسعه یافتگی اقتصادی، اجتماعی، فرهنگی و خدماتی زیادی باهم داشته باشند( ,Amanpour ٢٠١٨) احمدی و خیاط زاده ١ (٢٠٠٦) بیان کردند روند توسعه شاخص های اجتماعی در شهر اهواز متناسب با توسعه پایدار نبوده است .
