Spatial-Physical Analysis of the Level of Vulnerability of Urban Worn Out Texture using VIKOR and ANPCase Study: central texture of Urmia city

Population increase, human presence, expansion of urbanization and irregular spatial have caused profound disturbances in the functional system of cities. Therefore, planning and management of natural events should be considered as a main purpose at all stages of planning and city development designs. The present study in term of purpose is considered as an applied research and using descriptive-analytical method. The worn-out textures of central district of the Urmia city with an area of 277/7 hectares as a case study is investigated. In this study, through the study of library sources and former studies, and as well as using experts opinions and specialists in the field of urban worn-out textures, effective indicators in the vulnerability of the study area in dimensions of physical, access, functional, environmental, economic, social, and managerial identification and the definition was. Then, using the Analytical Network Process (ANP) and Vikors Multi-Criteria Decision Making Method (VIKOR) to weighting each of the mentioned indicators and using Geographic Information System (GIS), the vulnerability maps of the area in different dimensions are provided. The results of the research show that from the study area of 36/11% has low vulnerability, 27/95% has moderate vulnerability and 35/22% has high vulnerability, which has the necessity of planning and taking measures to improve the environmental condition of urban worn-out textures in different dimensions.
