摘要:应用3种模型对人工落叶松林各器官(或分量)干物质率进行计算,并用哑变量方法分析各器官干物质率在树木不同部位上和不同龄组中的差异.结果表明:模型(Ⅰ)能较理想地得到各器官干物质率,同时给出较小的误差估计;各器官干物质率在不同状态下存在着不同程度的差异.
Three models were applied to calculate the dry matter ratio of different organs of artifical Larix olgensisHenry forests,and the dummy variable method was applied to analyze the differences of the dry matter ratio of different organs in various positions of a tree and at different age classes. The results show that Model(Ⅰ) can better obtain the dry matter ratio of each organ weight and provide less error estimation. There exist differences in the dry matter ratio of each organ under different circumstances.
