摘要：选择广西南宁市良庆区大塘镇横州村麻竹林为研究对象,采用方差分析、线形相关分析、主成分分析及回归分析等方法,探讨其地上器官生物量分配及模型优化。结果表明:立竹年龄对麻竹竹秆、竹枝的含水率有较大的影响,竹秆与竹叶、竹枝与竹叶的含水率差异显著,不同年龄年麻竹的竹秆与竹叶的含水率差异显著;胸径与竹秆、竹枝生物量的回归分析优化模型分别为:H=2.47+0.86D-0.029D2,R^2=0.94;H=1.48+3.41D-0.11D2,R^2=0.91。本研究建立的竹秆生物量与胸径的数学模型在一定程度上可以指导实践工作,并为麻竹林经营提供了理论依据。
Dendrocalamus latiflorus Munro in Hengzhou village, Datang town, Liangqing district, Nanning city in Guangxi was chosen as the research object to study allocation of aboveground organs＇ biomass and model optimization using the methods of variance analysis, linear correlation analysis, principal component analysis and regression analysis. The results showed that： it has a great influence of bamboo age on the moisture content of culm and branch of Dendrocalamus latiflorus Munro; the difference of moisture content between bamboo culm and bamboo leaves is significant, the same as bamboo branches and bamboo leaves, the optimization model for regression analysis between diameter at breast height （DBH） and bamboo culm biomass is H=2.47＋0.86D-0.029D2, R2=0.94; and the same model between DBH and bamboo branches biomass is H =1.48＋3.41D-0.11D2, R2=0.91.the mathematical model of bamboo culm and DBH established in the study can guide the practical word to a certain extent, and provide a theoretical basis for management of Dendrocalamus latiflorus Mtmro.
