对湖北 6大生态区 11个县 (市 )不同类型森林可燃物及潜在火行为进行了研究 ,结果表明 :湖北森林可燃物按树种组成、可燃物空间分布连续性等指标划分 7种类型 ,按火强度等指标将潜在地表火行为分为 4级。高强度地表火发生在易燃系列的Ⅰ～Ⅲ种类型中 ,Ⅳ、Ⅴ类型只发生低强度地表火。不同类型的可燃物应用不同模式的防火林带预防和控制森林火灾 ,湖北省绝大部分森林以单层灌木防火带为主 ,部分地区必须建立乔灌复层防火林带防止树冠火 ,而单层乔木防火带不宜采用。难燃树种 (包括防火树种 )与目的树种块状混交是条带状防火林带模式的变形 ,可以有效地防止树冠火 ,是一种可以大规模推广应用的模式
The combustibles and potential fire behaviors of different types of forest in 11 counties (cities) in 6 major ecological zones in Hubei Province were studied. The results showed that: There are 7 types of combustible materials in Hubei Province, which are classified according to tree species composition and continuity of spatial distribution of combustibles. Fire intensity and other indicators will be potential surface fire behavior is divided into four levels. High-intensity surface fires occur in the Ⅰ ~ Ⅲ types of flammable series, and Ⅳ and Ⅴ types occur only in low-intensity surface fire. Different types of combustibles Application of different modes of fire-retardant forest belt to prevent and control forest fires, the vast majority of forest in Hubei Province to single-layer shrub fire-based, in some areas must establish multi-layer fire prevention and protection of canopy fire, and single-layer trees Fire belt should not be used. It is a model that can be popularized and applied on a large scale because of the deformation of banded fire-retardant forest zone mode, which can effectively prevent canopy fire because of the mixture of fire-retardant tree species (including fire tree species) and the destination tree species
