摘　　要：以不同年龄、不同密度的落叶松(Larix olgensis)人工林为研究对象,基于19块标准地95株标准木的树干解析、枝解析的生物量数据,研究不同大小树木因子(胸径、树高、冠幅等)与单木各分量(树干、枝、叶)生物量之间的关系,应用统计分析软件建立落叶松单木各部分生物量的回归模型。利用单木各部分生物量回归模型方程估测落叶松人工林各林分的总生物量,并分析了不同年龄及林分密度下林分生物量的变化规律:林分的生物量随年龄的增加而不断增长,树干的生物量的比例是最大的,同时也是随着年龄的增长而不断的增加,而树枝和树叶的生物量的比例比较小,林分的生物量随林分密度的增加而不断增加。最后建立林分生物量模型,为落叶松人工林的研究提供基础资料,为了解落叶松人工林的生产力,对其进行合理经营提供科学依据。Based on the biomass data from stem and branch analysis of 95 trees in 19 sample plots,with different ages and densities of larch（Larix olgensis） plantation as study object,the relationship between different factors（diameter at breast height,tree height,crown,etc.） and individual tree components（stem,branch,leaf） biomass was studied,and the regression models for various parts of biomass of individual larch were established using statistical analysis software.The regression models were used to estimate the total biomass of larch plantation stand.Variation of stand biomass in different ages and stand densities was analyzed.It showed that stand biomass increases with age,the proportion of stem biomass is the largest,which also increases with age continuously,but the proportion of biomass of branches and leaves is relatively small.Stand biomass increases with stand density.Finally,stand biomass model for larch is established.The results provided basic information on larch plantation for research and scientific basis for its reasonable management,facilitated the understanding of the productivity of larch plantation.
