| 摘要: |
| 以广东省深圳市14个裸露边坡治理工程为研究对象，分析比较了受损生态系统修复后各边坡的植物群落物种多样性特征。调查结果显示：边坡植物群落中共有120种植物，其中，频度相对较高、适应性相对较强的物种有马缨丹、银合欢、类芦、叶子花、大红花等11种；从群落组成结构看，边坡植物群落主要形成了乔灌草群落结构，飘板植槽的植被覆盖率和物种多样性指数均较高，物种分布较均匀，说明飘板植槽边坡群落结构相对稳定均衡；根据重要值结果可知，乔木层主要物种有台湾相思、银合欢、秋枫、木菠萝、小叶榕等，灌木层主要物种有簕仔树、山毛豆、马缨丹、猪屎豆，而草本层以类芦、异叶地锦为主。 |

| Abstract: |
| In this article, the characterization of fourteen plant communities on exposed slopes in Shenzhen were investigated. The results showed that there are 120 kinds of plants growing in these communities and 11 kinds of them (such as Lantana camara, Leucaena leucocephala, Neyraudia reynaudiana, Bougainvillea spectabilis, Hibiscus rosa sinensis, etc.) had high frequency and well adapted to the severe environment. The structure of plant community had three levels, including tree, shrub and herbaceous layers. The plant coverage and community diversity indexes on planting slot technology were higher, and species were even distributed. It implied that the structure of community on planting slot was more steady and balanced. Dominant species with high important value included Acacia confusa, Leucaena leucocephala, Bischofia javanica, Artocarpus heterophyllus, Ficus microcarpaand so on in tree layer, and Mimosa sepiaria, Tephrosia candida, Lantana camara, Crotalaria pallid in shrub layer, herbaceous species were Neyraudia reynaudiana, Parthenocissus dalzielii |
