چکیده مقاله :

یکی از مباحـث عمده و اساسی در نظام برنـامه ریزی جامع،مساله توسعه موزون و هماهنـگ است که در قالب توسـعه مناطق یک جامعه مطـرح می گردد.بکارگیری معیارها و روشهای کمی به منظور سطح بندی سکونتگاهها در سیستم فضایی مناطق شهری از سویی منجر به شناخت میزان نابرابری نقاط سکونتگاهی و از سوی دیگر معیـاری برای تلاش در زمینه کاهـش و رفع نابرابری های موجود میان آنها می گردد. هدف این مقاله،سنجش و ارزیابی سطـوح برخـورداری مناطق22گانه کلانشـهر تهران در جهت نزدیک شـدن به عدالت اجتماعی،توسعه فضایی و دستیابی به میزان نابرابری های منطقه ای از لحاظ شاخص های مورد بررسـی است.روش پژوهـش توصـیفی و تحلیلی می باشد. 42 متغیر انتخابی از طریق مدل آنتروپی شانون وزن دهی شده و از مدل کمیTOPSISبرای رتبه بندی اسـتفاده گردید. در میان مناطق شهری کلانشهر تهران برخوردارترین منطقه به لحاظ توسعه یافتگی،منطقه 5 با ضریب اولویت 0.584و فروبرخوردارترین، منطقه 17 با ضریب اولویت0.256می باشد.

چکیده انگلیسی:

Development is an exponential phenomenon which requires basis changes in cultural and social structures on one hand and economic growth and reducing poverty on the other hand. Imbalance and high concentration are from characteristic of the Third World Countries. These characteristics are the results of polar growth policies according to which some locations are strategic while others are marginal. Urban planning faces with issues such as understanding and analyzing the potentialities as well as the determination of the development level of a given city. One of the major and essential topics in comprehensive planning system is harmonious development issue that is introduced in terms of development of districts of a community. Paying attention to coordinating the areas based on providing them all items of economy, social, facilities, welfare and equipment is of the issues which can pave the way to get to justly distribution of sources to unity all areas with the quantity and quality aims of the outstanding huge national plans and policies. Utilization of quantitative criterions and methods to level the settlements in space systems of urban zones causes to recognize the extent of inequality of settlements from one side and is, from the other side, a criterion to try to decrease and remove the existing inequalities among them. The objective of this paper is to assess and evaluate the entitlement levels of the 22 zones of Tehran metropolitan to get closer to social justice, space development and to reach to regional inequalities regarding the studied indexes. The research method is descriptive and analytic that utilized TOPSIS quantitative model for ranking. The most entitled district regarding development is district 5 with priority coefficient of 0.584 and the least entitled one is district 17 with priority coefficient of 0.256. Finally, considering the social justice criterion and necessity of equal sharing of sources and city services to decrease the social differences between north and south zones of Tehran, we have to devote sources to different areas considering the areas justice. I mean we have to do it in a way that: - The needs of each zone population are met; - Devote most of the budget to the zones with most investment attraction to the areas with the least investment attraction which can guide and control the move of budget into the poor zones in the true way; - By building some worthy applications, in or next to poor zones, decreasing in Capitation level for incompatible uses, and trying to increase the zones quality with making a change in the kind of the city zones usages and providing services, especially the ones which are providing services, especially the ones which are municipal responsibilities to make the same level of progress among different zones; - The setting of appropriate density levels within area; - Adequate existing public transport capacity available or likely to be available within a reasonable development timescale; - The relationship and linkages between the area to be (re)developed and established neighborhoods, including the availability of existing community facilities.
