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。
根據繫列調查資料，分析比較多箇單木競爭因子，用迴歸分析法建立瞭帽兒山天然次生林區色木（Acer mono Maxim．）單木生長模型。研究結果錶明：所選的常用的單木競爭指數與天然次生林下生長的色木的胸徑生長量相關不顯著，而對象木相對直徑（RD）、競爭壓力指數（CSI）等指標與胸高斷麵積定期生長量存在比較明顯的相關關繫。

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.
