帽儿山天然次生林区色木胸高断面积生长模型的研究

摘要

根据系列调查资料，分析比较多个单木竞争因子，用回归分析法建立了帽儿山天然次生林区色木（Acer mono Maxim．）单木生长模型。研究结果表明：所选的常用的单木竞争指数与天然次生林下生长的色木的胸径生长量相关不显著，而对象木相对直径（RD）、竞争压力指数（CSI）等指标与胸高断面积定期生长量存在比较明显的相关关系。%According to series survey data, single-selection competition indicators were compared. Single-tree growth model of Acer motto were set up by using regression analysis in Maoershan natural secondary forest areas. Result shows that： the selected common single-tree competition index , which are not significantly related with diameter growth of Acer mono in a natural secondary forest, have significantly correlation with relative diameter （RD） ＆ competitive stress index （CSI） ＆ periodic increment of breast-height basal area.
