| 中文摘要: |
| 采用空间代替时间等方法，研究红砂岩侵蚀区不同治理模式下植物多样性变化，为红砂岩侵蚀区植被恢复先锋植物筛选及治理提供科学依据。结果表明，试验区高等植物125种，生活型以草本植物为主，共62种，同时提出了乔木层、灌木层和草本层的优势物种；裸地自然恢复和湿地松纯林模式物种多样性最高，其次为针阔混交林模式，马尾松纯林模式最低。裸地自然恢复模式乔木层多样性较低，灌木层和草本层多样性较高，马尾松纯林模式不同层次物种多样性均最低。 |

| The change characteristics of plant diversity of different restoration models were investigated by means of substitution of space for time, to provide a scientific basis for the selection of pioneer plants for vegetation restoration in red sandstone erosion area. The results showed that there were 125 species plants in the studied area, which were dominated by 62 species of herbaceous plants; the dominant species in arbor, shrub and herbaceous layer were discussed and presented; the natural restoration and Pinus elliottii pure forest had the highest species diversity, followed by the broad-leaved mixed forest and Pinus massoniana pure forest had the lowest. In the natural restoration, the species diversity of shrub layer and herb layer was higher than that of arbor layer. The species diversity of different layers in the Pinus massoniana pure forest was the lowest. |
