摘要
把植物生态学的研究方法应用于园林植物群落,调查分析青岛八大关公共绿地园林植物群落的物种多样性,结果表明:八大关公共绿地有园林植物93种,隶属于42科69个属,其中频度较高的主要是刺槐、紫荆和砂地柏。乔木Margalef丰富度指数平均值为2.05,灌木Margalef丰富度指数平均值为1.36,Shannon-Wienner多样性指数为3.69,Pielou均匀度指数为0.93,可以看出乔木层比灌木层丰富度高,多样性指数相对较高。
Based on ecological investigating method, the species diversity of landscape plants community in Badaguan green space was investigated. The results showed that： there were 93 species of landscape plants belonging to 42 families and 69 genuses recorded in INs study. The higher frequency species were Robina pseudoacacia, Cercis chinensis and Sabina vulgaris in Badaguan green space. The average of Margalef index in sample connunities of trees were 2.05, the average of shrubs were 1.36, the Shannon-Wienner index was 3.69, the Pielou index was 0.93. The trees species abundance degree was higher than the shrubs, and diversity index of communities were high in this space.
