| 摘 要： | 针对目前北京市森林资源连续清查所采用的一元立木材积表没有数式、应用不便的问题,提出了根据胸径、材积成对值及相应的二元材积式,建立内含树高-胸径回归模型的一元立木材积式的方法,并建立了北京市7个树种组的一元立木材积式,为森林资源连续清查的材积估计提供了方便。

| Abstract: | The existing problems of one-way tree volume tables used in continuous forest inventory in Beijing were analyzed,and an approach for formulization of one-way tree volume tables was presented based on the tree height-diameter model.The one-way tree volume equations of 7 tree species established in this paper could fit the samples better,and might be applied to volume estimation in continuous forest inventory in Beijing. |
