Vulnerability Assessment of Urban Land-uses in March Passes with Trend of Passive Defence: a case study of Isfahan metropolitan

Urban land-uses planning is one of the most important plans which can be effective in providing secure and sustainable environment in cities. Reducing land-use vulnerability and efficient crisis management to decrease damage according to new trends of crisis management such as passive defence is nowadays one of the most important objectives which urban managers and planners are trying to accomplish in metropolitans. Each crisis occurrence specially human crisis (urban riots and unrests and second incidents caused by them such as rubbery, burning and etc) in metropolitans can damage land-uses and causes insecurity in cities. March passes of Isfahan can be so vulnerable too. It seems that the most vulnerable land-uses in 8 march passes, also the land-uses with high spatial distribution in march passes. Study and field observations in these passes and GIS mapping and calculating damage ratio of land-uses according to calibration function indicate that banks and financial institutes and central businesses located in march passes are so much vulnerable and must be protected during crisis occurrence and even before that. In other words, Multiplicity distribution of these two land-uses in march passes has caused their high vulnerability. Isolation, strict protection and special distribution equalization of these two land-uses are considered important strategies to reduce their vulnerability.
