Resilience Evaluation and Urban Ecological Power Against Earthquake with Emphasis on Environmental Components (Case Study: Tehran Municipality District 1)

Increasing population and growing urbanization have led to the growth and expansion of cities in uncertain locations, regardless of natural and biological parameters. The process of unplanned physical development has aggravated the vulnerability of cities to environmental hazards, which requires informed guidance and basic planning for environmental sustainability. Therefore, the present study intends to use the ANP model in a synthetic approach with GIS to evaluate the resilience rate and ecological power of a district of Tehran against earthquakes in relation to the eight main criteria slope, gradient direction, geological structures, fault type, distance From the bed of the rivers, the distance from the aqueducts, land use and distance from unsustainable areas in terms of urbanization) and 38 sub-criteria. The method of this research is descriptive-analytic with an objective purpose. The results of this study showed that 27.28% of the area (946.63 Hectares) has a very high resilience, 10.86% (376.97 hectares) has a high resilience, 23.46% (813.88 hectares) has a moderate resilience, 25.03% (868.60 hectares) has a low resilience and 13.34% (463.00 hectares) has a very low resilience against earthquake. In general, municipality districts located in the west of Tehran's municipality district 1 are less tolerable and less ecological power to earthquakes than other areas of the district.
