| 摘 要： | 为探讨北京市五环内居住区绿地植物种类、结构以及植物群落特性,於2005年5～8月进行机械布点,共调查乔木样方180个,灌木样方200个,草本样方1 095个.结果表明:①北京市居住区共有维管束植物68科178属273种.②从市中心到五环梯度群落物种多样性特征为:物种丰富度草本层＞灌木层＞乔木层;均匀度乔木层、灌木层＞草本层;多样性指数灌木层、草本层＞乔木层.③绿地结构类型中,乔灌草交互组成的复层结构占优势.

| Abstract: | In order to understand the plant species, structure and community characteristics of the green land in residential area in Beijing city, diverse plots had been set up including 180 sample plots for arbor, 200 for shrub and 1 095 for herbaceous in May-August of 2005. The results showed that (1) there totally were 273 species of vascular plant, belonging to 178 genera of 68 families; (2) the characteristics of community diversity could be identified as abundance of species: herbaceous layer>shrub layer>arbor layer; evenness: arbor and shrub layers>herbaceous layer; diversity index: shrub and herbaceous layers>arbor; (3) compound structure composed by inter-composition among arbor, shrub and herb took advantage over other structures. |
