摘要
对目前广西森林资源连续清查所采用的一元立木材积表所存在的问题进行了分析,提出了以从一元材积表反推出的树高—胸径数据为基础,通过建立树高—胸径回归模型得到一元立木材积模型的方法,并重新建立了广西6个树种组的一元材积模型,为森林资源连续清查的材积估计提供了更为方便适用的材积公式。
The existing problems of one- way tree volume tables used in continuous forest Guangxi are analyzed,and an approach for establishment of one- way tree volume models inventory in is presented based on the tree height-diameter model. The one-way tree volume models of 6 tree species established from the new method can fit the samples better,and may be applied for volume estimation in continuous forest inventory in Guangxi.
