摘要
本文采用树干解析方法对贵州野生山桐子生长过程进行了分析，研究结果表明：山桐子胸径、树高和材积随着树龄的增长而增长，山桐子胸径和树高生长的速生期大致在9-20年，20-25年左右进入成熟期，而山桐子材积进入成熟期较晚，这与山桐子胸高形数的变化有关；通过对山桐子各器官生物量的测定，在山桐子生物量结构中，单株山桐子各器官生物量分配呈现出树干〉树枝叶的规律。并以山桐子树高（H）、胸径（DB）为自变量，建立了相应的生物量方程。
The individual growth process of wild analysis method. The results showed that： the diameter Idesia polycarpa in Guizhou was analyzed by the stem at breast height （DBH）, the height and the volume of the Idesia polycarpa Maxim. increase with the tree-ages increasing. The fast growing stage is at the ages of 9-20 years, and the mature period is at 20-25 years, while the volume of timber enters the mature period later due to the breast height form factor of Idesia polycarpa Maxim. For the biomass structure of Idesia polycarpa, trunk is greater than those of branch and leaves. Using the DBH and the height as the independent variable, a biomass equation was established.
