Abstract :

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.
