چکیده

رشد پراکنده شهری، گسترش فیزیکی سریع و بی برنامه شهرها و در پی آن استفاده بی رویه از وسایل نقلیه موتوری، این مکان‌ها را با چالش‌های زیست محیطی فراوانی مواجه کرده است که حاصل آن افزایش آلودگی‌های محیطی و از بین رفتن زمینهای کشاورزی و افزایش هزینه زیرساخت‌های شهری بوده است. بنابراین جهت سامان دهی به چنین رشدی، از الگوهای نوین برنامه ریزی همچون رشد هوشمند استفاده می‌شود که این الگو بر افزایش تراکم شهری، اختلاط کاربری‌ها و کاهش استفاده از اتومبیل تأکید دارد و هدف اصلی آن تأمین سلامتی و رفاه شهروندان است، لذا با دستیابی به رشد هوشمند می‌توان زمینه تحقق توسعه پایدار شهری را فراهم نمود. پژوهش حاضر با روش توصیفی-تحلیلی و بهره گیری از 45 شاخص از جنبه‌های مختلف اقتصادی-اجتماعی، کالبدی، زیست محیطی و دسترسی، به تحلیل الگوهای رشد مناطق شهری اصفهان پرداخته است که در این راستا از مدل‌های تاپسیس و امتیاز استاندارد جهت رتبه بندی و تحلیل‌های تطبیقی استفاده گردید. نتایج حاصله بیانگر این است که؛ بر اساس مدل تاپسیس، مناطق 5 و4 کاملا برخوردار، مناطق 13و2 و6 برخوردار، مناطق 8 و12 نیمه برخوردار و سایر مناطق محروم می‌باشند و بر اساس مدل امتیاز استاندارد مناطق 13 و5 و4 کاملا برخوردار، مناطق 2 و 6 برخوردار، مناطق14و12 نیمه برخوردار و سایر مناطق محروم می‌باشند و نتایج کاربرد هر دو مدل تقریبا یکسان بوده است به طوری که در هر دو مدل، مناطق 5 و 4 برخوردار ترین منطقه و مناطق 9،10،11،7، 3، 1 جزء مناطق محروم بوده‌اند. با مد نظر قرار دادن نتایج حاصله، توجه به رشد هوشمند شهری در 14 گانه اصفهان امری اجتناب ناپذیر است.

1-Introduction
Urban sprawl Growth, rapid physical development and unplanned and subsequent indiscriminate use of motor vehicles, it is facing many environmental challenges.

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.
