Study on Growth Law of Cyclocarya paliurua in Mixed Plantation

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.
