| 摘 要： | 地表可燃物是林火研究与管理的重要对象。通过对塞罕坝机械林场森林类型的分类和典型小班调查,结果表明,塞罕坝林区各林分类型单位面积的地表可燃物载量各不相同,1 h时滞可燃物〉10 h时滞可燃物〉100 h时滞可燃物,1 h时滞可燃物是地表可燃物的最主要构成,1 h时滞可燃物的组成、结构和特点是影响地表火发生和蔓延的主要物质基础;林区单位面积载量接近发生重特大森林火灾的临界条件（30 t/hm2）,防火形势十分严峻,急需实施综合治理。 |

| Abstract: | The research and management of surface combustible fuel is an important object of forest fire.Through classifying the forest types and investing the Forest Subcompartment in Saihanba Mechanized Forestry Farm,the results showed that the surface fuel loads per unit area of various forest types were different in Saihanba forest with the order of 1 h delay combustible fuel>10 h delay combustible fuel>100 h delay combustible fuel.1 h delay combustible fuel was the fundamental ingredient of the surface combustible fuel.The composition,structure and features of 1hr delay combustible fuel were the main material foundation to influence the occurrence and spread of fire.The surface fuel loads per unit area of Saihanba forest was closed to the critical condition of serious forest fire(30 t/hm2).The fireproof situation is very serious and badly in need of comprehensive treatment. |
