摘要

Crises are the main reflection of life mismanagement. Therefore, what is important in the occurrence of accidents is resilience of a place that can improve the continuity of the region's environment and provide stability and dynamism in times of crisis. This research aims to calculate the level of spatial resilience in the face of fire in Region 19 of Tehran. This is an applied research and the sampling method is random. The weights of the factors were calculated using Expert Choice software and the inconsistency rate was less than 0.1. The validity of the questionnaire was calculated through the CVR index for the items in the form of a Likert scale and its estimated value was 0.49. The reliability of the questionnaire was calculated by Cronbach's alpha coefficient and SPSS20 software and its value was 0.82. The data were standardized using the hierarchical evaluation model and ArcGIS10.6 software. The model was designed using the VensimPLx32 system. Findings achieved by examining 3 criteria and 12 spatial indexes that identify the main features of resilience in Region 19 showed that Physical Resilience, Operational Resilience, and Infrastructural Resilience were prioritized respectively as the 1st, 2nd, and 3rd priorities with the importance factors of 0.12, 0.58 and 0.28. The results obtained from the spatial resilience zoning map show that 21.67% of the area (2,812,993 m2) has low resilience, and 43.79% of the area (5,682,805 m2) has medium resilience and 16.59% of the area (21,536,913 m2) has high resilience.
