چکیده مقاله :
زمینه و هدف: امروزه جزایر حرارتی شهری موجب تغییر در شرایط اقلیمی شهرها می‌شود که این امر در شرایط زیست شهری تأثیرگذار بوده و موجب کاهش آسایش اقلیمی در شهر می گردد. لذا برای مقابله با جزایر حرارت شهری، مدیران و برنامه ریزان شهری باید طرح ها و برنامه‌هایی در نظر بگیرند که علاوه بر ایجاد آسایش اقلیمی در شهر از مصرف بی رویه انرژی در شهر نیز جلوگیری به عمل آید. مقاله حاضر با هدف بررسی وضعیت تاب آوری مناطق 6 و 11شهر تهران در برابر جزایر حرارتی شهری انجام شده است.
روش بررسی: برای انجام تحقیق حاضر، از منطقه 6 شهر تهران محلات میدان ولیعصر و دانشگاه تهران و از منطقه 11 محله جمالزاده حشمت الدوله و محله ی فلسطین- انقلاب انتخاب گردیده است. در ابتدا معیارهای اثر گذار بر تاب آوری تعیین و اثر آن ها نیز مورد بررسی قرار گرفت و پرسش نامه مربوطه به وزن دهی معیارها در اختیار خبرگان قرار گرفته در نهایت اطلاعات پرسش نامه در نرم افزار expert choice تحلیل و اوزان مولفه و معیارهای مورد نظر استخراج گردید. با استفاده از مدل AHP وزن دهی شد و در محیط GIS به صورت لایه های رقومی مورد تحلیل قرار گرفته است.
یافته ها: نتایج نشان داد در محله دانشگاه تهران بخش های تاب آور به صورت پراکنده در بین بخش های با تاب آوری کم تر قرار گرفته و از توزیع یکسانی برخوردار نیست. در منطقه 11 نیز بخش شرقی محله فلسطین- انقلاب از تاب آوری بیش تری نسبت به بخش های غرب برخوردار است. محله حشمت الدوله جمال زاده نیز به طور کلی نسبت به محله فلسطین انقلاب از تاب اوری کمتری برخوردار بوده و تنها در بخش های کوچکی در بخش های شمالی از تاب آوری بیش تری برخوردار است.
بحث و نتیجه گیری: به طور کلی و طبق یافته ها، در منطقه 6 ، محله ولیعصر به استثنای بخش های شمال شرق و جنوب غرب نسبت به محله دانشگاه تهران از تاب آوری بیبش تری برخوردار است.
چکیده انگلیسی:
Backgrounds and research goals: Nowadays urban heat islands cause climate changes in the cities, which is an impactful event in the urban life and causes a reduction in the climate welfare on the city surfaces. Thus in order to confront urban heat islands, urban designers and planners should consider a number of programs to prevent the unnecessary consumption of energy in addition to the development of climate welfare. The following article is done aiming to analyze the sustenance of the district 6 and 11 in Tehran against the urban heat islands.
Research method: For the purpose of this study, Valiasr Square and University of Tehran from District 6 and Jamalzadeh Heshmat al-Dawlah and Palestine-Revolution neighborhoods from district 11 were selected. At first, the criteria affecting resilience were determined and their effects were evaluated and the questionnaire related to weighting of the criteria was provided to the experts was done. It was weighted using AHP model and analyzed in GIS environment as digital layers.
Findings: The results reflected the fact that the Valiasr neighbourhood has a more sustenance comparing to the neighborhood of Tehran University except for the northeast and southwest areas. In the neighborhoods of Tehran University, highly sustained areas are sporadically located in the areas with the lower sustenance and do not have identical distribution. In the district 11, the eastern area of Felestin-Enghelab area has a more sustenance comparing to the western areas, too. Heshmat ol-dowleh Jamalzadeh area has a generally lower sustenance comparing to the Felestin-Enghelab area and it is only included a few number of areas with high sustenance.
Discussion and conclusion: Generally and based on the findings, in the district 6, the Valiasr locality possess a higher level of sustenance compared to the locality of Tehran university, except for some parts in northeast and southwest.
