摘　　要：文章通过外业调查确定了辽东半岛地区的主要5种火险林型,分别为油松人工纯林、日本黑松人工纯林、栎树天然纯林、杂木天然林、刺槐人工纯林。阔叶树林型下的灌木层、草本层的种类和盖度均明显大于针叶树,针叶树的凋落物层盖度大于阔叶树。主要林型下地被可燃物的载量分布较高,变化范围为6.47～12.08t/hm2;地被可燃物燃烧性能是针叶树明显大于阔叶树,其综合燃烧性由大及小的排序:日本黑松人工纯林>油松人工纯林>天然栎树林>刺槐人工纯林>天然杂木林。In this paper, 5 major forest types in fire danger which were pure Pinus tabulaeformis stands, pure Pinus thunbergii stands, pure natural Quercus spp.tands, natural miscellaneous stands and pure Robinia pseudoacacia stands respectively in Eastern Liaoning Peninsula areas were confirmed by field surveys. Species and coverage of shrub strata and herbage strata in broad-leaved forest types were markedly greater than that in needle-leaved forest types, and coverage of litter strata in needle-leaved forest types was greater than that in broad-leaved forest types. Distribution of loading capacity of combustible matter of ground-cover in major forest types was high, ranged from 6.47 to 12.08t/hm^2. Combustibilities of combustible matter of ground-cover in needle-leaved forest types were markedly than that in broad-leaved forest types, and the comprehensive combustibilities were in the following order: pure Pinus thunbergii stands, pure Pinus tabulaeformis stands, pure natural Quercus spp.stands, pure Robinia pseudoacacia stands and natural miscellaneous stands.
