摘　　要：采用典型抽样法,对郑州城市园林植物群落的种类组成和物种多样性进行了调查统计和分析。结果表明:1)3种不同类型绿地植物种类共计186种,隶属于72科133属;2)公园绿地的乔木层、灌木层和草本层物种α多样性指数均高于居住区绿地和道路绿地;3)公园绿地的β多样性指数均高于居住区绿地和道路绿地,居住区绿地和道路绿地之间的β多样性指数较小。针对郑州城市园林植物群落物种多样性的实际调查情况,提出加大乡土植物的运用,注意丰富季相景观和植物群落垂直结构层次的建议。By using typical sampling method,the species composition and the species diversity of plant community in the urban gardens of Zhengzhou were investigated and analyzed. The results showed that: 1) There were 186 plant species,belonging to 72 families and 133 genera in three urban green space types. 2) Compared with the residential green area and road green space,the park green space possessed a higher α diversity indexes in arbor layer,shrub layer and herb layer. 3) The β diversity indexes of the park green space was the highest among the three urban green space types. However,there is a small gap in β diversity indexes of the residential green area and road green space. According to the actual situation on species diversity of plant community in city parks of Zhengzhou,some suggestions are proposed like increasing the type of native plants and enriching seasonal landscapes and vertical structure level of plant community.
