混交比例对马尾松针阔混交林植被碳贮量的研究

his paper compared five different mixed proportions (0-20%，21%-40%，41%-60%，61%-80%，81%-100%) masson pine mixed woods. The effect of stand structure on biomass and carbon storage are studied. The author built biomass relational modle between DBH and defferent organs of masson pine, and the carbon relational modle between mixed proportions and different stand layers. The results showed that stand biomass and carbon storage was significant different with the change of masson pine proportions. The maximum average of biomass and carbon storage shows in the proportion of 41%-60%, which is 83.17 tohm-2 and 41.98 tohm-2, and the ability of carbon sink is significantly higher than other mixedwood proportions in this condition.
