| 摘 要： | 利用林分密度指数(SDI)作为天然林的林分密度测度,来反映天然林区天然林分中林木之间的竞争水平,利用地位级指数(SCI)代替地位指数来反映天然林区林分立地质量。结合这2个因子以Schumacher生长曲线为基本模型形式建立了天然林全林分生长和收获模型,模型包括断面积生长预估模型、林分蓄积量预估模型、郁闭度预估模型和蓄积枯损率模型。从模型的拟合和检验结果来看,模型的效果良好。

| Abstract: | The Stand Density Index(SDI) was introduced as a measure of stand density for the natural forest to reflect the competition level between trees in natural forest area.The Site Class Index(SCI) was used for replacing site index to reflect the site quality of natural forest.The Schumacher growth function was selected as base model for developing stand growth and yield model for natural forests including basal area growth model,stand volume model,canopy density model and mortality volume model.From the fitting... |
