北京喇叭沟门林区森林燃烧性及防火区研究

该文根据北京市怀柔县喇叭沟门自然保护区的自然条件和森林分布状况 ,对森林和林区植被的易燃特性进行了研究和分析 .选取了植物 (树种 )组成、郁闭度、林分年龄、森林类型、坡向、坡度、海拔高度等 7个林分因子作为燃烧性分量 .通过对各小班的燃烧性综合指标的计算、排序 ,划分了 5个森林燃烧性等级 .并在此基础上 ,对喇叭沟门乡进行了防火区划分 ,为制定自然保护区规划和开展森林防火工作提供了依据

Study on the forest combustibility and the fire districts in Labagoumen forest region

Located in Huairou County, Labagoumen Nature Reserve owns the biggest area of nature primary forest in Beijing region, but the forest fire hazard has been increased in recent years. According to the nature conditions and forest distribution of the area, the paper discussed the inflammability of the forest vegetation and chose seven forest stand factors which included the composition of plants (trees), crown density, age of stand, exposure, slope, altitude, as the combustible vectors for the calculation and ordination of the comprehensive combustible index of each sub compartment. In the light of that, the 5 ratings of combustibility were divided in the paper, which was the basis for the further fire districts' division in Labagoumen area. The results would be helpful to the drawing of forest fire program of the Nature Reserve and the developing of forest fire protection in the area.
