对长白山阔叶红松林、云冷杉林和亚高山岳桦林根系生物量的研究结果表明：３种森林类型根系总生物量排列顺序为阔叶红松林＞云冷杉林＞岳桦林；同土层深度下，根系生物量大致上也有上述规律，但第Ⅱ层根系生物量为云冷杉林＞阔叶红松林＞岳桦林；３种森林类型的根系生物量占其地上生物量及其总生物量的比例随着海拔升高而增加；根系大部分集中在０～６０ｃｍ土层中。
The results of root biomass measurements of broad-leaved Korean pine, spruce-fir and sub-alpine Betula platyphylla forest in Changbai Mountains showed that the order of the total biomass of the three forest types was broad-leaved Korean pine forest> spruce-fir forest> Under the layer depth, the root biomass also generally have the above rules, but the root biomass of the second layer is spruce-fir forest> broad-leaved Korean pine forest> Betula platyphylla; the root biomass of the three forest types accounts for above-ground biomass and its total The proportion of biomass increased with the elevation; most of the roots concentrated in 0 ~ 60cm soil layer.
