| 摘要: |
| 以广西南宁市国有高峰林场 48 a 生木荷 Schima superba 人工林为研究对象，探讨其生长规律、生长模型。结果表明：木荷人工林平均胸径为 20.68 cm，胸径生长速生期为 0~12 a，胸高形数为0.48~3.33，符合培育大径材要求，胸径最优生长模型为威布尔（Wei bull) 模型；平均树高为 23.54 m, 树高生长速生期为 0~14 a，树高生长模型为二次曲线 (Quadratic) 模型；平均材积为 0.359 8 m3，材积生长模型为威布尔（Wei bull) 模型。 |

| 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. |
