以内蒙古巴林右旗为研究区域,依据中国林业行业标准《全国森林火险区划等级》(LY/T1063-2008),选取树种燃烧类别、人口密度、路网密度、防火期月平均降水量、气温、以及风速等6项火险因子数据,运用数理统计方法和聚类分析法得出各个苏木乡镇的森林火险等级并完成火险区划。结果表明:1)幸福之路苏木拥有1个国家级自然保护区,幸福之路苏木火险等级提高一级为Ⅱ级,其他地区为Ⅲ级;2)进行聚类分析,按照火险程度由高到低分为3类,索博日嘎镇和大板镇为聚类1,查干沐沦苏木为聚类2,其他地区为聚类3。研究巴林右旗地区的森林火险等级并进行火险区划,有利于减少当地森林火灾导致的生命和财产损失。

Bairin Right Banner of Inner Mongolia was chosen as the study area based on Chinese forestry industry standard “national forest fire division level”(LY/T1063-2008).The data of six fire risk factors,the tree species category,burning population density,road network density and monthly average precipitation of the fire control period,air temperature and wind speed,were selected and statistical method and clustering analysis method were used to get the township forest fire danger rating and fire division.The results showed that:(1) Xingfuzhilu Township has 1 national nature reserves,and the grade of fire danger of Xingfuzhilu Township is grade II,and the other areas are class III.(2) Cluster analysis was carried out according to the degree of fire danger from high to low,which was divided into 3 groups.Suomaga town and Daban Town were cluster 1.Chagan Mu was cluster 2,and other areas were cluster 3.The research on forest fire danger and fire division of Bahrain Right Banner can reduce the loss of life and property caused by the local forest fire.
