摘要: 运用非线性联立方程组建模理论建立红松立木相容性生物量模型,然后利用模型计算出人工红松各个样地林木各器官和样地总生物量。以林分年龄、林分平均胸径、林分密度等因素为制约条件,讨论分析林分生物量在林木各器官之间的分配规律,并且探究林分年龄、林木大小和林分密度的变化对林分生物量的影响。结果表明:幼龄红松人工林林分生物量与平均胸径成正相关关系;林分密度对林分生物量影响较大,并且随着密度的增大而增大,且最适合的林分密度范围是1 000~1 400 株·ha-1;红松人工幼、中龄林林分生物量各器官分配规律相同,表现为树干>树根>树枝>树叶,地上生物量占林分生物量79%左右;林分地上和地下生物量大概呈3.8∶1的比例。

Abstract: Two compatible biomass equations of Pinus koraiensis single tree were built using nonlinear simultaneous equations modeling theory, then biomass of each tree organ of every plot was calculated. The forest biomass distribution in tree organs based on forest age, diameter at breast height and forest density was analyzed. Furthermore, the effect of main forest factors on forest biomass was discussed. The results were as follows: Young age P.koraiensis plantation forest biomass are positively correlated with the average diameter at breast height; Forest density has a great effect on forest biomass and the most suitable forest density is 1 000-1 400 N·ha-1; The distribution law of young and middle-age P.koraiensis plantation forest biomass are the same, stem>root>branch>leaf, biomass of aboveground forest is the main part of stand biomass and accounts for about 79%; The proportion of aboveground and underground biomass is about 3.8∶1.

Key words: biomass, Pinus koraiensis plantation, compatible biomass model, stand density, Mengjiagang forest farm
