混交林中青钱柳生长规律的研究

Study on Growth Law of Cyclocarya paliurua in Mixed Plantation

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4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.

Growth course of Cyclocarya paliurua were divided into 4 stages by ordinal cluster analysis method based on having analyzed the growth process of the mean and subdominant stems in mixed plantation. The first stage is the young forest stage during 1～3 years old, the second is the fast-growing stage between 4 and 14 years old, the third one is the pole stage from 15 to 26 years old, and the fourth stage is the mature stage after 26 years old. The study was helpful to recognize growth course of Cyclocarya paliurua and to provide foresters with credible theoretical bases for rational management and intermediate cutting.
