摘要
森林火灾突发性强,蔓延速度快,破坏性大,处置救治困难,危害严重。在参考国内外森林火险区划研究现状和发展趋势的基础上,以小陇山李子林场为研究对象,采用聚类分析法和加权叠加法,计算森林火险值,划分各区域火险等级。结果表明,在李子林场157个林班中,中级以上火险等级林班95个,林地面积19 928.4 hm^(2);极高火险等级林班31个,林地面积6 125.57 hm^(2),主要集中在村镇、干道周边。总之,李子林场火险等级普遍较高,是及其容易发生森林火灾的地区。
Forest fire has the characteristics of strong sudden,fast spreadsng,great destrustion,difficult treatment and serious harm.Based on the research status and development trend of Forest Fire Risk Regionalization at home and abroad,this paper takes Xiaolongshan plum forest area as the research object,calculates the forest fire risk value(FFR)by using cluster analysis method and weighted superposition method,and divides each regional fire risk grade.It is found that the area of plum forest area with intermediate fire risk grade is 19928.4 km^(2),95 forest areas;the area of plum forest area with high fire grade is 6125.57 hm^(2),31 forest areas(157 forest areas in total),mainly concentrated in villages and towns around the main road,the risk of forest fire is high and prone to forest fire.
