| 为深入研究广东始兴南山保护区的地带性植被亚热带常绿阔叶林的物种格局特征，在保护区
设置了 1 hm2 的固定监测样地，对样地主要物种的空间分布格局及其关联性进行了研究。结果表明：面积
为 1 hm2 样地中共有 94 个乔木树种，3 359 个植物个体，在群落占优势的这 4 个物种为罗浮栲 Castanopsis
fabri、栲 Castanopsis fargesii、华南木姜子 Litsea greenmaniana 和罗浮柿 Diospyros morrisiana。华南木姜
子和罗浮柿的分布格局主要呈现聚集分布，但罗浮栲和栲的聚集程度较低，物种的分布格局受物种特性
和生境异质性的影响。群落主要物种的关联性不明显，整体竞争不明显，群落会继续演替。 |

| Abstract: |
| In order to study the species pattern characteristics of the zonal vegetation subtropical evergreen
broad-leaved forest in Nanshan Reserve of Shixing, Guangdong province, a 1 hm2
forest plot was established
in the reserve, and the spatial distribution pattern and correlation of the main species in the plot were studied.
The results showed that, in the sample plot of 1 hm2
, a total of 3 359 individuals, belonging to 94 species were
recorded. The four dominant species in the community were Castanopsis fabri, Castanopsis fargesii, Litsea
greenmaniana and Diospyros morrisiana. The distribution patterns of L. greenmaniana and D. morrisiana were
mainly concentrated, but the concentrations of C. fabri and C. fargesii were low. This was related to species
characteristics and habitat heterogeneity. There was no obvious correlation between the main species in the
community, no obvious overall competition, and the community will continue to succession. |
