| Abstract: | Based on the investigation on 48-year-old Schima superba plantation in Gaofeng state-owned forset farm in Nanning, Guangxi, the growth regularity and growth model were studied. The results showed that the average DBH of S. superba plantation was 20.68 cm, the fast growing periods for DBH was from 0 to 12 years, the breast-height form factors of S. superba trees was 0.48~3.33, qualifing for cultivation requirements of big-diamer trees. The optimal growth models for DBH are Wei bull equation. The average tree height was 23.54 m, the fast growing periods for tree height was 0 to 14 years, The optimal growth models for tree height is Quadratic equation. The average volume was 0.3598 m3 , and the volume growht trend fifits the Wei bull equation. |
