ABSTRACT
To allocate fire resources rationally and prevent forest fires effectively, based on secondary indicators, such as the causal factor, vulnerability, exposure, and emergency rescue ability, thirteen tertiary indicators such as temperature, precipitation and elevation were selected to construct the comprehensive risk indicator system and evaluation model of forest fires in Hunan Province. A fuzzy analytic hierarchy process is used to assign indicator weights, and ArcGIS software is used to draw the comprehensive risk zoning map of forest fires in Hunan Province. The results show that the main influencing factors of cause factor, exposure, and emergency rescue capability indicator are residential density, population density, and firefighting investment, and their weight values are 0.2064, 0.3835, and 0.3949, respectively. The comprehensive risk levels of forest fires in Hunan Province are mainly level 2 and 3, and the average fire risk index of Hunan Province is 0.908. Among them, the east of Changde City, the north of Yiyang City, and the west of Yueyang City have the lowest risk of forest fires, and the average fire risk index is 0.864, 0.862, and 0.858, respectively. Huaihua City has the highest risk of forest fires, with an average fire risk index of 0.954.
