摘要
以21年生闽楠人工林为研究对象,调查分析了不同坡位对闽楠生物量及其分配格局的影响。结果表明,不同坡位对闽楠生长及各器官生物量积累和分配均有不同的影响。闽楠生长量及生物量积累表现为下坡位>中坡位>上坡位;就各器官生物量分配率而言,下坡有利于叶、大根和细根的积累,上坡有利于干、骨骼根、中根及小根的积累。
By taking Phoebe bournei plantation aged twenty-one as test material, the effects of different slope positions on its growth and biomass distribution were analyzed in this paper. The growth and biomass were showed ranking as downslope 〉 mesoslope 〉 upslope. Downslope had better effect on biomass distribution of leaf, large root and minor root, and upslope better on that of trunk, stump root, middle root and fine root.
