Analysis of the relationship between defenseless spaces and environmental variables using the GIS. Case study: Region 3 of Ardabil.

Unprotected urban spaces are a threat to the security of citizens. Therefore, their organization is essential for the promotion of social security. The purpose of the present study is to explore and analyze the relationship between urban defensible spaces and environmental variables.

The research area is Ardebil Municipality District 3. Urban independent spaces include 172 independent variable locations of this study identified through field surveys. Exploratory variables included population and building density, income groups, passage network quality, physical texture of urban textures, social cohesion of neighborhoods, land and building prices, and land use. GIS techniques such as mean center method, standard deviation ellipse, spatial autocorrelation for spatial analysis and geographic regression method were used to explain the correlation between variables.

Crime spaces occur in less extensive areas and tend to focus within certain areas of Region 3. The number of these spaces decreases to the north and south. Also, these defenseless spaces have spatial self-correlation and are distributed as clusters and imbalances at the regional level. As a result, certain ranges are the focus of the defenseless spaces studied and follow the centralized pattern. Also, there is a significant relationship between 8 environmental variables studied in the study of defenseless urban spaces in the 3rd district of Ardabil city.

Research findings show that there is a significant relationship between defensible spaces and environmental variables. The result is that environmental variables have a direct impact on the formation and growth or destruction and elimination of defenseless spaces.
