摘　　要：叙述了辽西走廊及辽西北部低山丘陵区域的主要林型──油松、刺槐、杨树、樟子松及沙棘等林下地被可燃物种类组成和载量情况。结合１９８７～１９９６年该地区林火发生现状分析得出：林下地被可燃物种类组成及负荷载量是林火发生的关键要素之一，与林火发生频度密切相关。The Composition and amount of forest fuel in major forest types: pure stands of Pinus tabulaefor-mis , Robinia pseudoacacia , Populus spp., Pinus sylvestris var. mongolica and Hippophae rhamnoides that exist in western Liaoning corridor and northern part of hilly and mountainous area in the west of Liaoning Province were surveyed. Analysis on occurrence of forest fire during 1987 to 1996 indicates that the composition and load of forest fuel are key factors which is highly correlated with the frequency of forest fire.
