摘要
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。
Root biomass of broad-leaved Korean pine forest(BLKPF), spruce-fir forest(SF) and subalpine berch forest(SBF) in Changbai Mountain was studied in this paper. The results showed that the total biomass of root was in the order of BLKPF>SF>SBF, as well as root biomass of every layer, but SF>BLKPF>SBF in the Ⅱ layer; With the increase of altitude height, the ratios of root biomass to above-ground biomass and to the total biomass were increasing; Most roots were in 0~60cm soil layer.
