摘　　要：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 。Six ecological areas of different kinds of forests in 11 counties(or cities) cologi in Hubei Province were studied in this paper. The result shows that the forest fuel in Hubei was divided into 7 types according to indices such as the tree species form and the distribution, the continuity of fuel in space and so on ,the latent five behavior was divided into 4 degrees according to indices such as the fire intensity and so on.The high intensity fire on the earth surface took place in the typeⅠto Ⅲ of the combustible series,the middle and low ones took place in the type Ⅵ and Ⅶ,and the type Ⅳ and Ⅴ only appeared the low intensity fire on the earth's surface. Different types of fuel must be protected by fireproof bolts of suitable modles,most forests in Hubei Province should be protected by the shrub fireproof belt, a portion of forest must be protected by the shrub and plant fireproof belt ,unlined plant fireproof belts were not suitable to Hubei . The middle of the hard combustible plants or fireproof ones mixed with objective plants was disguised form of the fireproof belt,the modle can protect crown fire effectively, it was a modle that can be applied and disseminated extensively.
