Analysis of the spatial structure of places prone to accidents (fires) in the city using the capabilities of Arc GIS software

For a long time, the fire incident has been the main problem of urban management and sustainable urban development. In addition to human and social factors, the occurrence of fires is largely influenced by the urban physical environment. The current research is applied in terms of purpose and descriptive-analytical in terms of nature. The available information on fire incidents (during the five-year period of 2014-2018) was mapped and analyzed in terms of space and time using the spatial analysis available in GIS. Then, using spatial analysis of hot spots, the pattern of spatial distribution of fire incidents in Ardabil city was determined. Also, Kernel Density Estimation (KDE) technique has been used to analyze high or low fire incidents in Ardabil city. According to the results of the research, the density of incidents is higher in the central parts and in spots from the outskirts of the city. About (40%) of the city's area are located in areas with a high and very high risk of vulnerability. The degree of vulnerability is high in the central part of the city and neighborhoods that have unfavorable socio-economic and environmental conditions.
