摘  要:
以闽北某县(区)域为研究对象,选取地物类型、坡度、海拔、坡向和离居住区远近作为林火评价主要因子,采用层次分析法和综合评价法,对研究区域森林火险情况进行了定量评价.按火险等级,将全区分为5类火险区,实现了研究区森林火险等级的区划.无、低、中、高、极高5类火险区分别占研究区的25.51%、59.27%、10.95%、4.22%和0.05%;居民居住区及周边的火险等级较其他地方高.

摘  要:
Based on AHP and factor weights union method,the forest fire risk in an area of North Fujian was quantified by the factors including vegetation type,slope altitude,aspect,and settlement buffer area was classed into 5 risk ranks.The safe,low,moderate,high and extremely high fire risk zones accounted for 25.51%,59.27%,10.95%,4.22% and 0.05%,respectively.Compared with other areas,the fire risk in inhabitant community and the peripheral areas was higher.
