摘要
研究证明，长白落叶松幼树各器官生物量的分配随年龄增长的变动规律是：在幼年时期，枝和叶的生物量所占比重较大，根的生物量比重很小；１１ａ开始幼树生物量迅速上升，随年龄的增加，树干所占的比值迅速增加，枝叶所占的比值明显减少．
The varing laws of the biomass distribution in each organ of young Larix olgensis as agegrowth are studied in this paper,they are as the following,the proportion of the biomass of branch andleaves are possessed bigger while roots are very small in young stage,the biomass of young trees increasevery soon from 11 ages.As age growing,the ratio of trunk increases very soon,at the same time,branch-es and leaves reduce obviously.
