تبیین مدل مفهومی نقش‌آفرینی فضای شهری در ارتقای کیفیت زندگی در بافت‌های تاریخی

فضای شهری در یک بستر تاریخی، علاوه بر دارا بودن همه عملکردهای متعارف خود که در سایر محیط های شهری نیز عهده دار است، باید نقش خود را در ترازی بالاتر و چند وجهی منطبق با ویژگی های یک بافت تاریخیِ هویت مند ایفا نماید. بر این مبنا هدف اصلی پژوهش حاضر،کشف چگونگی ارتباط و نحوه برهمکنش مولفه‌های فضای شهری با  اجزا و ارکان متشکله جریان زندگی در بافت‌ تاریخی است؛ به نحوی که بتوان با مدیریت و استفاده شایسته از ظرفیت‌های فضای شهری در بستر بافت تاریخی، کیفیت زندگی ساکنان و کاربران آن را ارتقا بخشید. این مهم به نوبه خود حفظ ساکنین بومی در محدوده بافت تاریخی، بازگشت مهاجران از محدوده و پایداری اقتصادی، اجتماعی و محیطی را موجب خواهد شد. روش تحقیق پژوهش حاضر توصیفی_ تحلیلی، استدلال منطقی و در نهایت دلفی سازی و نظرسنجی از خبرگان است. بدین ترتیب که ابتدا به مولفه‌های فضای شهری و کیفیات ناظر بر آن پرداخته شده، سپس ابعاد و سنجه‌های کیفیت زندگی شهری بررسی و شاخص‌هایی از آن که به فضای شهری و کیفیت محیطی اشاره دارد و موضوع کار طراحی، برنامه‌ریزی و مدیریت شهری است، بر اساس دیدگاه‌های نظری و تحقیقات انجام شده گذشته مشخص شده است. در گام بعدی شاخص‌های استحصال شده با ویژگی‌های خاص بافت تاریخی مورد پایش و بازبینی قرار گرفته است. شاخص های به دست آمده از دلفی (با تعداد 91 شاخص) با اظهارنظر حدود 40 نفر از خبرگان رشته و حرفه به 64 شاخص تقلیل یافتند. در نهایت نتایج آن در قالب مدل مفهومی نقش فضای شهری در ارتقای کیفیت زندگی در بافت‌های تاریخی شهری ارائه شده است. این مدل مفهومی از شش مولفه تشکیل شده؛ شامل مولفه زیست محیطی با معیارهای «کیفیت زیست خرد فضاها»، «پایداری زیست محیطی»، مولفه تجربی_زیبایی شناختی با معیارهای «هم پیوندی بافت جدید و قدیم»، «کیفیت منظر شهری و ارتباط فضایی»، مولفه عملکردی با معیارهای «تنوع استفاده از محیط»، «سرزندگی وکیفیت محیطی»، «ایمنی و امنیت» و «حمل ونقل و دسترسی»، مولفه اجتماعی_فرهنگی با معیارهای «سرزندگی و انسجام اجتماعی»، «حفظ تعادل جمعیت»، مولفه ی اقتصادی با معیارهای «سرزندگی و ثبات اقتصادی»، «انعطاف پذیری برنامه های توسعه» و مولفه ی زمان با معیارهای «مدیریت زمان در فضاهای همگانی»، «تداوم مکان» که شاخص ها را تعریف کرده اند.

Conceptual model of the role of urban space in improving the quality of life in historical contexts

Highlights: Improvement of the quality of life in historical contextsPresentation of a conceptual model of the role of urban spaces in public lifeWithout the interaction of the environment, community, and economy, the quality of life will not improve.There are many physicalfunctional and environmental qualities in urban public spaces that can guarantee the success of the field in satisfaction of residents and users of historic districts. IntroductionIn addition to performing all its standard functions in other urban areas, an urban space in a historic district should play its role at a higher multifaceted level matching the characteristics of a historic district with established identity. Accordingly, the present work aimed to discover how the components of an urban space, on the one hand, and the constituent elements of the flow of life in a historic district, on the other, are linked and interact so as to enable reasonable management of urban space potentials in a historic district and their proper application to enhance the quality of life for the residents and users.Theoretical FrameworkThe model consisted of six components defining the following factors: the environmental component, with life quality in micro‑spaces and environmental sustainability as criteria; the empiricalaesthetic component, with oldnew area integration and quality of urban landscape as criteria; the functional component, with variety in environment usage, environmental liveliness and quality, safety and security, and transportation and accessibility as criteria; the sociocultural component, with social liveliness and cohesion and maintenance of population balance as criteria; the economic component, with economic liveliness and stability and flexibility of development plans as a criterion; and the temporal component, with time management in public spaces and continuity of place as criteria.Generated based on the urban space components, the presented conceptual model offered a new approach to urban planning and management, and was concerned with all the urban regeneration measures adopted in historic districts. Functioning on local, regional, urban, and extramural scales, it can also assume applications in the quality assessment of measures adopted in public arenas within historic districts.MethodologyThe above strategy will in turn keep indigenous residents in historic contexts, have immigrants to those areas return, and bring about socioeconomic and environmental sustainability. Employing logical reasoning, the Delphi method, and expert opinions, this descriptiveanalytical study first discussed the urban space components and their qualitative requirements. Next, the dimensions and measures of the quality of urban life were analyzed, and their factors concerning the urban space and environmental quality and topics formed on urban design, planning, and management were identified based on the theoretical views found in the literature. In the next step, the factors extracted based on the characteristic features of historic districts were monitored and reviewed. The 91 factors obtained from the Delphi method were reduced to 64 after views and comments from about forty experts in the field were applied. Finally, the results were presented as a conceptual model describing the role of urban spaces on quality‑of‑life enhancement in historic urban districts.Results and DiscussionAccording to the findings, there are many physical–functional and environmental qualities in public urban spaces that can guarantee the arena’s success in provision of the residents and users of historic districts with satisfaction. However, taking notice of economic activities and social mobility in these districts is fundamental to the effectiveness of a measure adopted for enhancement of the quality of life in public arenas within historic districts. Meanwhile, a rise in the sensitivity of local communities to the values of historic districts and the potentials of public arenas for enhancement of the quality of life therein encourages them to assume an active role in the application of these arenas and the local communities’ socioeconomic potentials in enhancement of the quality of public arenas. This can also enable these communities to express problems and propose solutions; in some cases, it can even lead to innovative financing ideas for project implementation. In tandem with urban planning, it ensures the sustainability of public arenas in historic districts, and improves the quality of life for their residents and users. Therefore, the issues of sociocultural livability and dynamic economy are the cornerstones of the formation of quality spaces within historic districts, and the quality of life will not improve regardless of the triad of the environment, society, and economy.ConclusionThe presented conceptual model, based on the urban space components, offers a new approach to urban planning and management, and is concerned with all the urban regeneration measures adopted in historic districts. Functioning on local, regional, urban, and extramural scales, the model can also assume applications in the quality assessment of measures implemented in public arenas within historic districts. Here is a brief description of the intervention measures adopted for these districts and their regeneration process based on the proposed model.The sociocultural component. Contextualizing, contributing to/collaborating with, providing a process orientation for, innovating, and influencing the satisfaction of residents and users in public areas, utilizing the contribution/collaboration from the users of public arenas, delegating authority to non‑governmental organizations for utilization management, allowing for effective, constructive interaction among the organizations involved in the quality enhancement of historic districts and observing the pertinent legal frameworks, clarifying the procedures and promoting the accountability of officials, and respecting the cultural, social, and economic structures of life in the district.The empiricalaesthetic component. Integrating old and new spaces within public arenas while respecting the features of their historic districts and taking notice of the mass and space simultaneously and avoiding shell designs.The environmental component. Reducing environmental pollution and protecting energy resources and the natural heritage.The functional component. Providing a favorable impact on space liveliness and enhancing social inclusion to be able to hold various events.The economic component. Helping businesses flourish and promoting tourism.The temporal component. Taking notice of nightlife, holding seasonal, monthly, and weekly events and recognizing the sense of place and making an effort to preserve it within the environment.
