摘　　要：对辽东3也区3种主要林型——油松、落叶松及标类杂木林的地被可燃物载量进打了调查研究．比较分析了地被可燃物载量与林分密度、林龄及坡位、坡向的关久。结果表明：3种林型地被可燃物载量由大到小依次为陈类杂木林．油松林及落叶松林．并且载量的分布与林分密度、林龄及坡位、波向密切相关。In this paper. the status of loading capacity of fuels of ground cover for three major forest types ineastern Liaoning was studied. The major forest types were stands of Pinus tabulaeformis. Larix sp. andmiscellaneous stands of Quercus sp. The relations between loading capacity of fuels of ground cover anddensity of stands, age of stands, slope sites and slope exposure were also analysed. The results indicatedthat loading capacity of fuels of ground cover of three major forest types were in the following order:miscellaneous stands of Quercus sp. Pimus labulaeformis stands and Larix sp. stands. Furthermore, theloading capacity were closely correlated with density and age of stands, sites and exposures of slope.
