Zoning of high-risk areas in forests using GIS (Case study of forests of Kermanshah province)

Forest fires and its spread are one of the natural phenomena across the globe. Natural phenomena are always complex and there are many factors affecting them, the phenomenon of fire in forests and its extension is not an exception and occurs annually in different parts of the country. Considering the ecological importance of forest ecosystems and the increasing development of remote sensing technology and geographic information systems, we can identify areas that are most at risk of this phenomenon. This research is a descriptive-analytical method, the collection of information with Use of library resources. The area under study is Kermanshah forests. In this study, topographic parameters (slope, direction and altitude), accessibility (distance from roads, distance from settlements and distance from rivers (tribes and tribes), tribal passage, accident points Growth at the nomadic crossing site, land use, pasture distribution and forest distribution are considered as effective parameters in the fire zoning and using the ahp model, different weight layers have been given. Finally, by applying the weights to the layers, the layers were phased out and the gamma 0.9 was prepared from the layers. According to the weights, criteria and sub-models, the map of areas with a fire hazard in three areas, low Risk, medium risk and high risk areas.
