Assessment of Structural-Natural Resilience of Urban Land Use  Case Study: Tehran Metropolitan Area 4

The metropolises have a considerable population and are full of man-made spaces. Taking advantage of the resilience approach of urban land use allows urban planners and managers to minimize the probability of physical and financial damage when natural disasters occur with sufficient preparedness. The purpose of this study was to identify the dimensions and factors affecting structural-natural resilience and to determine indicators of urban land use resilience in Tehran's 4th district. The present study belongs to the applied research group. Librarian and field method were used for data collection. The theoretical framework of the research was developed in the form of a library method by reviewing the theoretical and empirical texts related to the subject of research. Criteria and factors affecting land use resilience were reviewed by sources and a questionnaire was used to prepare the final list of criteria and their prioritization. After completing the questionnaires by 20 faculty members and experts in urban and rural planning, environmental planning and urban planning, the criteria were weighted by FANP method. Ground cover extracted from Landsat 2017 satellite imagery was categorized into ENVI 4.8 software. The stratified layers were then grouped in fuzzy IDRISI environment and in ARC MAP. The effect of weight of each of the effective criteria on the resilience of the layers and the composition of the maps was determined by the resilience. The results show that the average structural-natural resilience of land use in this area is 0.86 and resilient.
