| 摘要: |
| 采用植被生态学方法，对1997—1998年在广东内伶仃岛设定的固定样地进行调查和研究，着重分析了内伶仃岛植被中4个主要典型群落的物种组成、群落结构和物种多样性等特征，揭示了各主要群落15 a来的演替情况。结果显示，马尾松-梅叶冬青+豺皮樟群落、马尾松-檵木+豺皮樟群落、马尾松-银柴-豺皮樟群落以及布渣叶+小叶榕-黄牛木群落4个群落优势种的组成发生了较大的变化。其中，马尾松群落中的马尾松衰退明显，优势地位被阔叶种群取代；布渣叶群落的优势种布渣叶优势更加明显。此外，这4个群落的结构更加复杂，主要体现在乔木层、灌木层、林间藤本植物和林下草本植物的组成更加多样化。经过15 a的演替，各群落的物种多样性均提高。3个马尾松群落正朝向更加复杂的南亚热带阔叶林演替，而布渣叶群落也同样向更加复杂的结构演替。 |

| Abstract: |
| In this paper, vegetation ecology methods were adopted to study the vegetation succession of four fixed samples set in 1997 and 1998 in Neilinngding island. The species composition, community structure and species diversity of four major typical communities were mainly analyzed. The results showed that, all the communities, including Pinus massoniana-Ilex asprella Litsea rotundifolia var. oblongifolia community, Pinus massoniana-Loropetalum chinense Litsea rotundifolia var. oblongifolia community, Pinus massoniana-Aporosa dioica-Litsea rotundifolia var. oblongifolia community, Microcos paniculata Ficus microcarpa-Cratoxylum cochinchinensis community, had a large change in species composition. Pinus massoniana in the Pinus massoniana communities declined obviously, and its dominant position was replaced by the broadleaf species. Microcos paniculata, dominant species of Microcos paniculata Ficus microcarpa-Cratoxylum cochinchinensis community, had more obvious advantages. In addition, the structures of the four communities had been more complex, mainly reflected in the more diverse composition of tree layer, shrub layer, vine plant and herbaceous plant. Species diversity indexes indicated that the species diversities of the four communities were improved. The results above indicated the Pinus massoniana communities in Neilingding island were in progressive succession to the more complicated Subtropical broad leaved communities, and the Microcos paniculata community was in progressive succession to a more complicated one.\ |
