摘要
根据 30株天然水曲柳解析木资料 ,运用相关分析原理 ,对其胸径、树龄、树高之间关系进行了探讨 ,并利用其回归方程 ,编制了天然水曲柳胸径、树龄、树高相关表 。
Based on the analysis of the data of 30 sample trees, the correlation between the breast diameter, age and height was revealed and the regression equation was established. The correlation table founded on the equation was worked out which manifested the correlation between breast diameter, age and height of the trees. It provides a simple and reliable method in selective breeding of Fraxinus mandshurica.
