The Spatial Modeling of Proximity in Special Land Use from Passive Defense Point of View in Ahvaz Metropolis

Ahwaz metropolis through critical and unique position in the realms of energy strategy and geo-economic، geo-culture، and geostrategic position of Iran، for Iran from the perspective of an urban passive defense has strategic position. Hence، the optimum model of location-specific applications (critical) with respect to adjacency issues is one of passive defense requirements in this city. This study after the recognition of the principles of passive defense and spatial standards in place، had extracted the location - proximity to critical land use in Ahwaz. This study is a functional and descriptive - analytic study. Required information are collected in the library and survey and preparation، update and competition of database. The study sample consisted of all critical land use categories، urban installations، facilities management، military - security، support، transportation within the city of Ahvaz. Prevailing approach to data analysis is spatial analysis and for analysis of spatial data have used the combined model of FGIS- FAHP. In order to analyze the data، after extracting spatial standards، the map distances have prepared according to the principles of proximity and vicinity in the Special lane use. The Research findings have shown that 57/0 percent of especially land use located in the critical zone of the high risk and the region of 7 known as the most vulnerable and the region of 5 known as the safest regiona in ahvaz.
