| 摘要: |
| 在全面路线踏查的基础上进行典型人工群落样地调查，结果表明：梧桐山人工群落主要有台湾相思群系Form. Acacia confusa、大叶相思群系Form. Acacia auriculaeformis、马占相思群系Form. Acacia mangium、木荷+油茶群系Form. Schima crenata+ Camellia oleifera等；物种组成共有135种54科109属，并以双子叶植物为主，乔木、灌木性植物种类相对草本和藤本状植物较丰富；各群系物种多样性均表现为灌木层＞乔木层，且乔、灌木层的物种多样性总体上以木荷油茶群系为最高，其次为台湾相思群系，而马占相思群系和大叶相思群系为较低。建议遵循地带性群落演替规律并结合景观生态学、森林生态美学等进行阶段性的人工补植主要乡土树种，起到改善小气候环境并促进生态功能强、观赏价值高和发展稳定的城市森林群落形成。 |

| Abstract: |
| Based on all-around and typical plant community investigation, the results showed that the main plantation communities of Wutong Mountain in Shenzhen were Form. Acacia confuse, Form. Acacia auriculaeformis, Form. Acacia mangium and Form. Schima crenata+ Camellia oleifera. There were 135 species in the plant communities belonging to 135 genera, 54 families, most of which were dicots, and the species of the arbor and the shrub were more abundant than the herb and the liana. And the species diversity of every formation was that the shrub layer> the tree layer, and the species diversity of the tree and the shrub layers in the Form. Schima crenata+ Camellia oleifera was the highest, and the Form. Acacia confuse took second place, and the others (Form. Acacia auriculaeformis and Form. Acacia mangium) were lower. It was suggested that by replanting the main native species in different phases, with the discipline of succession of native community and combining with landscape ecology and forest eco-aesthetics, the urban forest communities could be improved to be more stable and the ecosystem function can become complete and the visual value also will increase. |
