| 摘 要： | 利用波谱分析方法中的谐波分析原理, 对陕北白桦个体生长过程进行了不同层次的分析。结果表明:白桦个体的树高、胸径和材积生长动态波动规律与Logistic 模型不完全相同, 树高在20 年后与Logistic 模型吻合, 胸径整个过程均不吻合, 但材积生长与Logistic 模型基本一致;应用波谱分析方法分析树木生长过程的动态规律, 比Logistic 模型更准确。

| Abstract: | The individual growth dynamics of Betula platyphylla Suks population in north of Shaanxi province have been analyzed at different levels according to concordant spectrum principle and method of spectrum analysis. The result shows that the growth of the height, breast height diameter and volume of Betula platyphylla population individuals are not suited to the model of the Logistic regulation of general plant growth. The height growth regulation coincide with Logistic only after 20 years old; the growth of breast height diameter is totally different from Logistic model; however, the volume growth suits to the Logistic model. The spectrum analysis is an efficient method to analyze the growth process of woody plant compared with Logistic model. |
