天然黄山松竞争指标及林分竞争生长模型的研究

A Study of Competitive Index and Growing Model of Pinus taiwanensis

根据 10块黄山松天然林标准地每木调查资料 ,对林木间的竞争与生长关系进行研究。在选择适合黄山松天然林的竞争指标的基础上 ,建立林分生长模型。研究结果表明 :将林木胸径、对象木树冠面积及树冠重叠面积结合在一起所形成的竞争指标最能客观反映黄山松间的竞争关系 ;以竞争指标为基础 ,结合林分平均年龄、林分平均胸径。

With the data collected from 10 plots of Pinus taiwanensis, the relations between competition and growth among trees have been discussed. Through analysis and simulation using permenent sample plot data, a competitive index reflecting objectively the competition and growth pattern of Pinus taiwanensis plantation was selected; based on the selected competitive index, stand growing models containing competitive index, age, diameter at breast height (DBH) and mean growing index have been established, which can be used to predict stand growth accurately.
