【摘要】 研究了丛生竹种大木竹(Bambusa wenchouensis)种群的生物量结构,并对其各器官生物量与胸径(DBH)和地径的相关模型进行了拟合。结果表明:大木竹各器官生物量的分配中,竹秆所占比例较大,为总生物量的73.1%,远超过毛竹(Phyllostachys edulis)等竹种的相应值。大木竹各器官生物量之间及其与胸径、地径间均具有较好的相关性,其中鲜秆质量(W1)、全株鲜质量(W4)与胸径(D)间相关关系的拟合模型W1=0.370 3D2.092 2和W4=0.512 2D2.039 1可以较准确地估算出各器官生物量的大小。更多还原

【Abstract】 The biomass structure of Bambusa wenchouensis population was studied in this paper.The regression models of each biomass component based on DBH and the diameter of culm base were constructed.The result showed that culm biomass of B.wenchouensis accounted for 73.1%,much higher than that of Phyllostachys edulis.DBH,diameter of culmbase and the different components of B.wenchouensis were highly corretated each other.The model of culm fresh weight（W₁） and total fresh weight（W₄） based on DBH（D） were W₁=0.3703 D^2.0922 and W₄=0.5122 D^2.0391 respectively.By using these models,the different biomass components of B.wenchouensis could be estimated in practice.更多还原
