摘要
采用组间平均联结法对深圳市主要植被群落进行划分,并应用Gleason丰富度指数、Shannon-Wiener指数、Simpson指数和Pielou指数对主要植被群落的物种多样性水平进行比较分析。结果表明:深圳市城市森林可以划分为5个群系组和31个群落类型;各群落类型的物种多样性均表现为灌木层>乔木层,常绿阔叶人工林的乔木层和灌木层的生物多样性指数均最低,常绿落叶阔叶人工林乔木层丰富度指数、Shannon-Wiener指数、均匀度指数均最高,常绿阔叶人工林的乔木层优势种比较明显。
Based on field investigation in Shenzhen, the major types of plant community were classified with a meth- of between-groups linkage by SPSS software. Four diversity indices : Gleason richness index, Shannon-Wiener in- dex, Simpson index and Pielou index, were used to analyze the species diversity. The results showed that the Shenzhen' s urban forest could be divided into five formation groups and community types. The shrub stratum of ur- ban forest community had a higher value in richness index and diversity than arbor stratum. The richness index and diversity of evergreen broadleaved plantation' s shrub and arbor stratum were the minimum and the diversity indices of evergreen deciduous broadleaved plantation' s arbor stratum were the highest. The dominant species of evergreen broadleaved plantation' s arbor stratum were distinct.
