مقایسه تطبیقی توسعه یافتگی مناطق شهری با استفاده از روش های ارزیابی چند شاخصه (مطالعه موردی: کلان شهر اصفهان)

یکی از اهداف اصلی در برنامه ریزی شهری تخصیص عادلانه ی امکانات، خدمات و کاهش نابرابری ها می باشد. لازمه ی این کار شناسایی جایگاه مناطق و نواحی شهری نسبت به یکدیگر از لحاظ توسعه است. درک و شناخت میزان سطوح برخورداری مناطق مختلف نسبت به یکدیگر باعث شناخت نقاط ضعف، قوت، فرصت ها و تهدیدهای آتی و در نهایت موجب موفقیت برنامه ریزی شهری می شود . به کارگیری معیارها و روش های کمی جهت سطح بندی سکونتگاه ها در سیستم فضایی نواحی از طرفی منجنر به شناخت میزان نابرابری نقاط سکونتگاهی و از طرفی دیگر معیاری جهت تلاش در راستای کاهش و رفع نابرابری های موجود میان آنها محسوب می گردد. بدین منظور تحقیق حاضر قصد دارد تا با بررسی و تحلیل مجموعه ای از شناخص های توسعه درمناطق شهری اصفهان اقدام به سطح بندی درجه توسعه یافتگی مناطق شهری نمایید تا بدین شیوه مشکلات و کمبودهای هر منطقه را شناسایی و با اولویت دهی به مناطق در خصوص تخصیص و توزیع منابع و امکانات شهری براساس شاخص های مورد بررسی گامی در جهت ایجاد توسعه متعادل مناطق بردارد. به همین جهت در پژوهش حاضر سعی شده با بهره گیری از سه تکنیک تاکسونومی عددی، موریس و تاپسیس و استفاده از 63 شاخص توسعه در زمینه های محیطی اکولوژیک، اجتماعی فرهنگی، اقتصادی و کالبدی فضایی به تعیین و تحلیل سطوح توسعه مناطق شهری اصفهان پرداخته شود. رویکرد حاکم براین پژوهش توصیفی-تحلیلی و از نوع کاربردی توسعه ای است، یافته های پژوهش نشان می دهند کنه منطقه ی سه براساس دو مدل تاپسیس و تاکسونومی در رتبه ی نخست و طبق مدل موریس در رتبه ی دوم توسعه یافتگی قرار می گیرد و منطقه ی یازده براساس نتایج هر سه مدل به عنوان محروم ترین منطقه محسوب می گردد.

a comparative study of the development of urban areas by using multi criteria evaluation methods (case study: isfahan metropolis)

introduction one of the main goals in urban planning is the equitable allocation for facilities, services and reducing inequalities. this requires to identify the status of development in urban areas according to each other. better understanding and recognizing the amount of the enjoyment levels of regions and comparing them to each other causes their weakness, strength, opportunities and future threats to be recognized, and finally cause the regional and zonal planning to be succeeded. the use of quantitative criteria and procedures for ranking settlements in space system also led to identification of measure the inequality settlement and on the other hand this is a measure to try to reduce and eliminate disparities between them. therefore, this study aims to analyze a set of development indicators, in isfahan urban regions to ranking development of the urban regions of isfahan and in this way the problems of each region will identify and by prioritize the regions for the allocation and distribution of resources and amenities based on surveyed criterions created a balanced development of its regions. methodology one of the common criteria in urban planning is the classification of the regions and districts based on different development indicators. in the present study, by using three techniques including numerical taxonomy, morris and topsis and using 63 development indices in environmental - ecological, social -cultural, economic and physical-spatial areas, urban development levels have been analyzed in district of isfahan.result and discussion the results of the study show that district three is in the first rank based on topsis and taxonomy models and in the second place according to the morris model, and district eleven considered the most deprived area based on the results of all three models. in terms of economic indicators, the rank of district three is first in all three models, and district fifteen by three models, morris, taxonomy, and topsis is in the last place. in terms of cultural indicators, five district was ranked first in two taxonomy models and morris, and district eleven is the most deprived. in terms of physical indicators, district three was ranked first in all three models and fourteen district was ranked the last. according to the topsis model, eleventh district was the most deprived area. in terms of environmental-ecological indicators, district eleven is the most deprived area and based on both the morris and topsis models, the four district is the most developed area. conclusion as it is shown in the maps provided, the deprived areas are located on the western and eastern margins of the city and it can be considered as a danger, because in the absence of proper consideration and reduction of inequality these areas will be on the verge of crises such as social, cultural and economic damage, and eventually we will see phenomena, such as informal housing, flooding and other social disasters in these areas, in this stage of problems, organize and repair structures will be much more difficult, so the need of early consideration for these areas is well understood.
