تحليل الگوهاي رشد هوشمند شهري در مناطق چهارده‌گانه اصفهان بر اساس مدل‌هاي برنامه‌ريزي منطقه‌اي

An analyze of Smart growth patterns in fourteen areas of Isfahan metropolitan, Based on regional planning models

رشد پراكنده شهري، گسترش فيزيكي سريع و بي برنامه شهرها و در پي آن استفاده بي رويه از وسايل نقليه موتوري، اين مكان‌ها را با چالش‌هاي زيست محيطي فراواني مواجه كرده است كه حاصل آن افزايش آلودگي‌هاي محيطي و از بين رفتن زمينهاي كشاورزي و افزايش هزينه زيرساخت‌هاي شهري بوده است. بنابراين جهت سامان دهي به چنين رشدي، از الگوهاي نوين برنامه ريزي همچون رشد هوشمند استفاده مي‌شود كه اين الگو بر افزايش تراكم شهري، اختلاط كاربري‌ها و كاهش استفاده از اتومبيل تأكيد دارد و هدف اصلي آن تأمين سلامتي و رفاه شهروندان است، لذا با دستيابي به رشد هوشمند مي‌توان زمينه تحقق توسعه پايدار شهري را فراهم نمود. پژوهش حاضر با روش توصيفي-تحليلي و بهره گيري از 45 شاخص از جنبه‌هاي مختلف اقتصادي-اجتماعي، كالبدي، زيست محيطي و دسترسي، به تحليل الگوهاي رشد مناطق شهري اصفهان پرداخته است كه در اين راستا از مدل‌هاي تاپسيس و امتياز استاندارد جهت رتبه بندي و تحليل‌هاي تطبيقي استفاده گرديد. نتايج حاصله بيانگر اين است كه؛ بر اساس مدل تاپسيس، مناطق 5 و4 كاملا برخوردار، مناطق 13و2 و6 برخوردار، مناطق 8 و12 نيمه برخوردار و ساير مناطق محروم مي‌باشند و بر اساس مدل امتياز استاندارد مناطق 13 و5 و4 كاملا برخوردار، مناطق 2 و 6 برخوردار، مناطق14و12 نيمه برخوردار و ساير مناطق محروم مي‌باشند و نتايج كاربرد هر دو مدل تقريبا يكسان بوده است به طوري كه در هر دو مدل، مناطق 5 و 4 برخوردار ترين منطقه و مناطق 9،10،11،7، 3، 1 جزء مناطق محروم بوده‌اند. با مد نظر قرار دادن نتايج حاصله، توجه به رشد هوشمند شهري در 14 گانه اصفهان امري اجتناب ناپذير است.

Extended abstract 1-Introduction Urban sprawl Growth, rapid physical development and unplanned and subsequent indiscriminate use of motor vehicles, it is facing many environmental challenges. Resulting in increased environmental pollution and loss of agricultural land and urban infrastructure costs, so as to regulate this growth use of new models such as smart growth planning, this pattern, increased urban, mixed land uses and reduce the use of cars and the main emphasis on the welfare of its citizens. Growth of Isfahan areas in last year's resulting loss of agricultural land and increased environmental pollution and socio- economical problems. Such growth caused some areas had Low population density. The aim of the present study is: all areas of Isfahan city are experiencing urban sprawl? If not so, which Isfahan's area from use of smart growth indicator's is in priority? Identifying low priority areas will benefit from special attention. 2- Theoretical bases Term of smart growth first by Paris angindrhyng (mayor of Maryland) from 1990 – 2002 was costumed. Smart growth is referring to a set of land use and transportation principles that is at odds with the distribution. This movement aims to create and strengthen a sense of community, developed based on transportation, economic development, mixed – use neighborhoods, support the design of green buildings, pedestrian – oriented neighborhoods , offering a varied pattern of housing , protect open lands, farms and limit environmental fair share of the costs and benefits of development , has been formed to protect cultural resources. 3-Discussion 45 indicators in difference basis economical, social environmental and transportation with using of Antropy models had weight and from the grading Technique of topsis for grading urban area had used and results with standardized score model had compared with comparative form. According to the results fourteen Isfahan's area in four bands possessed full prosperous, prosperous, semi – prosperous, deprived was classified based on topsis areas 5 and 4. Thoroughly full prosperous and 6, 2, 13 thoroughly prosperous and 12, 8 semi prosperous and other areas in deprived was classified. According to the results of grading standardized score model indicates areas of 13, 5, 4 in full prosperous – 6, 2 in prosperous - 12 – 14 semi prosperous and other areas in deprived. 4 – Conclusion Isfahan Metropolis has experienced high growth and day by day increased environmental pollution and loss of agricultural land are faced .according to this research resulting,9 out of 14 areas in Isfahan, have been deprived of Smart Growth indicator, just 2 areas has full prosperous. Between area's people and smart growth is direct relation. 5 – Suggestions - Conversion of non – residential buildings, disused and abandoned to residential facility by granting priority areas - High density residential and mixed use especially with commercial and office use, with an emphasis on trails - To minimize the entry of private cars to the city center and to expand public transport - Incentive policies to increase density and refurbished old construction come to use them - Green and public spaces to strengthen the sense of place for residents and their participation in local decisions - using multiple places, such as parking use of the school in holidays - Space allocation and development of green roofs and green walls to the rooftops to reduce Environmental pollutants
