چکیده مقاله :
با گذشت بیش از چهاردهه از تهیه طرح‌های جامع و تعیین محدوده قانونی برای شهرهای ایران، هنوز ارزیابی دقیقی از موفقیت این ابزار صورت نگرفته است. همین عامل باعث شد این پژوهش به انجام این مهم پرداخته و به ارزیابی میزان موفقیت محدوده قانونی طرح جامع دوم تهران مبادرت نماید. روش تحقیق پژوهش بر پایه روش ارزیابی کمی و با هدف کاربردی است و تصاویر ماهوراه‌ای اصلی‌ترین داده مورد استفاده در این مقاله است. تجزیه‌و‌تحلیل و پردازش داده‌ها با بهره‌گیری از نرم‌افزارهای Envi و Arcgisصورت گرفته و انطباق مرز و محدوده رشد شهری طرح جامع و مرز واقعی بررسی شده است. یافته اصلی پژوهش دلالت بر این دارد که محدوده قانونی طرح جامع دوم کلانشهر تهران، نتوانسته بطورموثری توسعه شهری را کنترل کند. همچنین مشخص شد که ارزش شاخص مهار مرز رشد 15/0 است، که بر عدم توانایی مرز رشد شهری در محدود کردن توسعه شهری کلانشهر تهران اشاره دارد.
Industrial Revolution and subsequent developments were led to the revolution in urbanization in the second half of the nineteenth century and the revolution changed human settlement in other cities and resulted in unprecedented expansion of cities. This was an epidemic phenomenon that Iran would not be safe from it. In order to deal with the development and distribution of the city in Iran from mid-century imitation of the western planned systems, comprehensive plans that have in their hearts policies to control and limit urban growth were used. In the form of the comprehensive plans have been accomplished policies of the Green Belt to determine the physical limits of the city (urban growth boundary). After more than four decades, providing the first comprehensive plans for cities and for urban growth boundary, yet comprehensive and accurate assessment has not been made from success and effectiveness of the urban growth inhibition tools. Those factors caused we executed this research and in this research has been selected Tehran metropolis as study sample. After that, this study sample has been investigated in order to assess the measure of success and effectiveness of the urban growth boundary. In this research has been used qualitative research method. Research indicator has been derived from the theoretical foundations and satellite images and Envi 4.8 software has been used to verify adaptation comprehensive plan of urban growth boundary and the real border. The main findings of this research are follows: Urban growth boundary that has been determined in comprehensive plan 1371 not effectively control urban development. In the period 1371-1386, a large part of the new development outside of the urban growth boundary has been located. When the ability of urban growth boundary control by using of growth boundary inhibition was measured, the results were shown that the value of this indicator is 0/15 percent and the result means that urban growth boundary of comprehensive plan has no ability in limit of urban growth of Tehran metropolis. Size scope of the urban growth boundary specified in the comprehensive plan that has been determined in 1371 had been appropriate and had been more than the necessary amount. Thus, the failure of the urban growth boundary in respect to evolutions and developments in outside of the East Tehran metropolis and thrown out in the southern part is clear. Size scope of the urban growth boundary specified in the comprehensive plan that has been determined in 1371 had been appropriate and had been more than the necessary amount. Thus, the failure of the urban growth boundary in respect to evolutions and developments in outside of the East Tehran metropolis and thrown out in the southern part is clear.
