| 摘 要： | <正>本文应用多元统计分析中的典型相关分析方法对湖南朱亭人工杉木林的生长量与其立地条件之间的相互关系的分析结果表明,杉木的生长量与其立地条件之间存在着密切的相关关系。在生长量中以树高与立地条件的关系最为密切,而影响生长量的主要立地条件因子分别为经营级、坡位和土层厚度。应用这—方法可以分析出某一地区影响杉木生长的主要立地条件因子,从而为合理制定人工杉木林的经营措施提供理论依据。

THE METHOD OF CANONICAL CORRELATION ANALYSIS APPLYING TO STUDYING THE INTERRELATIONSHIPS BETWEEN THE INCREMENT AND SITE CONDITIONS OF CHINESE FIR |
| |
| Abstract: | The paper applies the method of canonical correlation analysis in multiva-riate statistical analysis to studying the interrelationships between the increment and site conditions of the Chinese fir plantation in Zhuting area, Hunan Province. The result shows that there is a significant correlation between the increment and site conditions of Chinese fir. Moreover the tree height in the increment is the most closely related to the site conditions, and the main factors affecting the increment in the site conditions are the management class, slope position and thickness of soil horizon.Therefore, the main factors affecting the growing of Chinese fir in site conditions may be analysed out by using this method. And, the reliable basis of theory can be provided for working out the rational management measure of the Chinese fir plantation. |
