| 摘 要： | 采用种群的生态位宽度、生态位相似性程度及生态位重叠度来衡量人工边坡植被恢复过程中群落发展方向和群落演替过程.对新(街)河(口)高速公路裸露边坡人工植被恢复过程中乔木层优势种群的生态位特征进行分析.结果表明,在该路域植被恢复过程中,山黄麻、黄金间碧玉、银合欢和构树的生态位宽度值均最高,但是乔木层优势种群之间对资源的利用相似性程度不大,种群之间的生态位重叠程度不高,这说明该路域植被在人工植被恢复过程中,乔木层优势种群在恢复期间仍然处于初级演替阶段,资源相对充足. |
| 关 键 词： | 高速公路 裸露边坡 植被恢复 乔木层优势种群 生态位特征 |

| Abstract: | The paper adopted niche breadth,niche similarity and niche overlap of a population to measure the direction toward community development and the progress of community succession in the course of slope vegetation restoration.The analysis on niche characteristics of most dominant population on arbor stratum indicated that Trema orientalis（L.） Bl.,Bambusa vulgaris cv.Vitata chia,Leucaena Leucocephala（L.） and Broussonetia papyrifera（L.） L＇Hert had the most niche breadth in bare slope vegetation restoration along the highway.But the similarity of making use of the resource and niche overlap between dominant populations on arbor stratum was not big.The phenomenon illuminated that the most dominant population was at the stage of elementary succession courses in artificial restoration.. |
| Keywords: | highway bare Slope vegetation restoration dominant population on arbor layer niche characteristics |
