| 摘 要： | 通过对铜陵叶山林场麻栎样木地上生物量调查,以胸径、树高为自变量,地上总生物量、树干、树枝、树叶生物量为因变量,选择相对生长式、幂函数式和多项式为生物量回归模型,拟合各模型参数、相关指数、回归剩余离差,并计算生物量估测误差。结果表明:麻栎树干、树枝、树叶和地上总生物量与胸径、树高存在显著幂函数关系,其方程分别为:树干W=6.571×10-4D1.8473H2.411、树枝W=1.163×10-4D2.9497H1.3223、树叶W=0.0032D1.5148H0.8821、总生物量W=9.354×10-4D2.0825H2.1154。树干与总生物量的预估精度均达90%以上。

| Abstract: | Based on an investigation of aboveground biomasses of sample trees of Quercus acutissima in Yeshan Forest Farm of Tongling County,the relative growth style,power function and polynomial were selected to be the biomass regression models,with DBH and tree height as independent variables,and total aboveground biomass and biomasses of the tree trunks,branches and leaves as the dependent variables.The model parameters and correlative indexes,regression residual errors were fitted and biomass estimation errors we... |
