| 中文摘要: |
| 根据松华坝水库天然林群落的不同海拔梯度以及不同坡向设置36个典型样方进行调查。对松华坝水库物种组成、种子植物区系、群落各层次物种的重要值以及植物多样性进行分析。结果表明：调查到维管植物300种；乔木层云南松种群占绝对优势；水库天然林从乔木到灌木再到草本，植物多样性水平递增；随着海拔的上升，植物多样性水平先升高再降低；从阳坡到半阴坡再到阴坡，植被多样性水平先升高再降低。 |
| 英文摘要: |
| According to different altitude gradients and slope directions of natural forest communities in Songhuaba Reservoir, 36 typical plots were set up for investigation. The species composition, plant flora, importance values of species at all levels of the community, and plant diversity of Songhuaba Reservoir were analyzed. The results showed that 300 species of vascular plants were investigated; the Pinus yunnanensis population in arbor layer was absolutely dominant; the level of plant diversity of natural forest in Songhuaba Reservoir increased from arbor layer to shrub layer and then to herb layer; with the increase of altitude, the level of plant diversity first increased and then decreased; from sunny slope to semi shady slope and then to shady slope, the level of vegetation diversity first increased and then decreased. |
