Abstract

The research was conducted on forest growth characteristics of Cinnamomum longepaniculatum planted in Yibin county by stem analysis method. The results showed that tree height, DBH and total volume increment of the 27 year old Cinnamomum longepaniculatum were 14.6 m, 17.0 cm and 0.141 722 m³, respectively. The annual increment of tree height reached the maximum at the age of 12, and its quantitative maturity age was about 13. Its critical growth period of DBH was in the first 18 years during plant growth. The current annual increment of volume reached the maximum (0.009 631 m³) at the age of 12, and its quantitative maturity age was about 28. The growth process of volume could be divided into three stages:1 year~9 years being slow growth phase, 9 years~18 years being fast-growing stage, and being progressive decelerational phase after 18 years.
