摘　　要：防火线是有效阻隔森林火灾蔓延的重要防火设施,在以山脊流水线为中线向两边开设防火线时,防火线宽度同时受到林下植被高度、坡度的影响,而在非山脊流水线上开设防火线时,防火线宽度只受林下植被高度的影响。本文根据田东县国有紫胶林场40多年的防火线开设经验及相关数据,对防火线宽度与林下植被高度及坡度等参数进行数模化,对本场及与本场具有相似气候、立地条件的林区防火线开设具有参考价值。The fire line is an important fireproof facility to effectively block the spread of forest fire.When the fire line is opened on both sides with the ridge line as the middle line,the width of the fire line is affected by the height and slope of understory vegetation at the same time,while when the fire line is opened on the non-ridge line,the width of the fire line is only affected by the height of understory vegetation.Based on 40 years of experience and relevant data of setting fire lines in stateowned lac forest farm in Tiandong County,this paper simulates the fire line width,height and slope of understory vegetation and other parameters,which has reference value for setting fire lines in this field and other forest areas with similar climate and site conditions.
