Abstract

Spatial modeling of social resilience as a new defense approach and identification of parameters affecting it plays a key role in the defense readiness of cities. The purpose of this study is to present a new approach based on geographic information system for social resilience modeling. This new approach has been used on a case-by-case basis for the city of Sarpol-e Zahab as one of the most risky cities in the country in recent decades. For this purpose, a set of 10 indicators and 29 criteria affecting social resilience was used. AHP weighting method has been used to determine the weight of different criteria and the WLC model has been used to combine effective criteria to produce a map of spatial potential of social resilience. Finally, to evaluate the efficiency of the proposed model, the correlation coefficient between the values of spatial potential of social resilience obtained from the WLC model and the accuracy of the social resilience map was calculated based on the information collected through a questionnaire.   The results of this study showed that among the indicators affecting social resilience, indicators of social capital and social vulnerability had the greatest impact on modeling social resilience. Also, most urban areas (60%) are considered as low-level and vulnerable urban areas in terms of social resilience, which indicates a decrease in urban defense capacity against shocks and accidents.
