摘  要：
对开化县木荷生物防火林带和杉木、马尾松针叶林的生长情况、林下植被、易燃物数量、表层土壤含水率等进行了调查测定。结果表明:1 h和10 h时滞易燃物干重木荷林带内地表分别为462.3、656.8 g/m2,杉木林地为874.6、1 282.8 g/m2,马尾松林分别为1 137.2、1 107.1 g/m2,木荷林内易燃物仅为针叶林的一半左右,木荷林带比针叶林具更强的抗地表火的能力;16年生木荷林地表1 h时滞易燃物干重,比11年生木荷林小,表明16年生木荷林带的防火性能较11年生时有所增强;此外,从山脚、中坡、山脊不同坡位的木荷林带比较来看,立地条件较好的山脚木荷林分生长旺盛,易燃物相对较少,防火性能高于山脊木荷林分,因此,应重视和加强低林龄及山脊部木荷生物防火林带的抚育管理,促进其生长旺盛,增强其对林火的抵抗能力。

摘  要：
Investigations were conducted on growth,understory vegetation,fuel quantity and surface moisture content under fire belt stand of Schima superba and conifer stands such as Cunninghamia lanceolata and Pinus massoniana.The result demonstrated that mean dried weight of surface fuels in fire belt forest with 1 hour and 10 hours retardance had 462.3g/m2 and 656.8g/m2,while that in conifer stands had 1 005.9 g/m2 and 1 195.0 g/m2,indicating better surface fire-resistance of fire belt forest.Dried weight of surface fuel in 16-year S.superba forest with 1 hour and 10 hours retardance was smaller that that in 11-year forest,demonstrating stronger fire-resistance with age.The result also showed that it had more fuels with 1 hour retardance in fire belt distributed at ridge.Countermeasures were offered for fire belt forest such as strengthening tending of young stand and that distributed at ridge.
