摘要
通过对青杉混交林中青钱柳平均木、亚优势木的生长过程进行分析,应用D、H有序样木Fisher分割法,将青钱柳的生长过程划分为四个阶段:1~3年为幼林生长期,4~14年为速生期,15~26年为干材生长期,26年以后进入成熟期,对了解该树种的生长变化过程有着重要意义,为合理经营、抚育间伐提供可靠的理论依据。
The mean trees and subdominant trees of Cyclocarya paliurua in mixed plantation were analyzed. By using ordinal cluster analysis method, its growth procession was divided into 4 stages. The first stage was the young forest one at the age of 1~3 years; the second stage was the fast-growing one at the age of 4~14 years; the third stage was the pole one at the age of 15~26 years and the fourth atage was the mature one after 26 years. The study is significant in making out the growth process of Cyclocarya paliurua and provides credible theoretical basis for rational management and intermediate cutting.
