Forest Fire Danger Rating and Fire Hazard Assessment in Chifeng City of Inner Mongolia

Taking Chifeng City of Inner Mongolia as the study area, according to the " Rank of the Regionalization on Nationwide Forest Fire Risk” (LY/T 1063—2008), 6 fire risk factors including tree species burning type, population density, road network density, monthly average precipitation during fire prevention period, temperature and wind speed were selected, and using data analysis method and cluster analysis method were used to obtain the forest fire danger rating and fire hazard assessment of each Banner and County in Chifeng. The results show that Bahrain Right Banner, Hexigten Banner, Harqin Banner, Ningcheng County, Aohan Banner and Hongshan District each have 1 national nature reserve, and 6 regions are upgraded 1 level to Grade I. Yuanbaoshan has 1 national forest park, and its fire danger rating is upgraded 1 level to Grade II and other regions to Grade II. Known by cluster analysis, the fire danger rating is divided into 4 categories from high to low, and Hongshan District is hazard class 1 level; Ar Horqin Banner is hazard class 2 level; Bahrain Left Banner, Yuanbaoshan, Ningcheng County, Harqin Banner, Aohan Banner, Linxi County are hazard class3 level; and other regions are hazard class 4 level. The research results can provide a practical reference for forest fire prediction and forest resource management.
