| 摘要: |
| 以隆林县森林资源二类调查的油茶（Camellia oleifera）林小班为研究对象，利用主成分分析法划分隆林县油茶林的主要立地类型，然后采用 5 个理论生长方程构建不同立地类型的油茶树高生长模型。结果表明：（1）影响隆林县油茶林分布的主要立地因子为土壤类型、坡度、地貌和坡向，隆林县油茶林的立地类型可划分为 54 种；（2）红壤缓坡低山阴坡、红壤缓坡丘陵阴坡、黄壤缓坡低山阴坡、黄壤缓坡丘陵阴坡、石灰土缓坡低山阳坡以及石灰土平坡低山阳坡立地类型的油茶最优树高生长模型均为Logistic 模型，黄壤缓坡低山阳坡的最优模型为 Korf 模型，石灰土缓坡低山阴坡的最优模型为 Gompertz模型。 |

| Abstract: |
| Based on the forest resource inventory and planning of Camellia oleifera stand in Longlin county，the main site types of C. oleifera stand in Longlin county were classified by principal component analysis. Five theoretical growth models were used to construct height-growth models of C. oleifera in different site types. The results showed that the main site factors affecting the distribution of C. oleifera stand in Longlin county were soil type, slope, landform and slope direction. The site types of C. oleifera stand in Longlin county wrer divided into 54 types. The optimal tree height-growth model of C. oleifera were the Logistic model on the site of gentle shady slope with red soil in low mountain, gentle shady slope with red soil in hill, gentle shady slope with yellow soil in low mountain, gentle shady slope with yellow soil in hill, gentle sunny slope with lime soil in low mountain, ?at sunny slope with lime soil in low mountain. The optimal tree height growth model of C. oleifera was the Korf model on the site of gentle sunny slope with yellow soil in low mountain. The optimal tree height growth model of C. oleifera was the Gompertz model on the site of gentle shady slope with lime soil in low mountain. |
