摘　　要：文章选择海口市两种城市绿地类型(综合公园、高尔夫球场)为研究对象,采用典型样方法对绿地中的植被情况进行调查,比较两者在物种多样性以及物种组成方面的异同。结果显示,在两种绿地的非人群游憩植被区中,乔灌草前10种指示种均有7种及7种以上不同;高尔夫球场和综合公园乡土物种数分别为150种和68种;高尔夫球场中除乔木层的Pielou均匀度指数低于综合公园之外,其他物种多样性指数均高于综合公园;物种群落组成上均有较大差异(Jaccard相异性指数最高达0.875,Bray-Curtis相异性指数最高达0.778)。应增加海口综合公园中的乡土物种使用比例,提升综合公园的景观特色;高尔夫球场部分绿地区域具有生物多样性保护和乡土植物维持的生态服务功能。This paper selects two categories of urban green space(multifunctional park and golf course)in Haikou City,China,to compare their difference and similarity in species diversity and species composition using the classical quadrat method.The results show that among the 10 top indicator tree-shrub-herbaceous species in the parts where no visitor is allowed to enter,there are more than 7 species which are different in the two categories of green space;the number of native species in golf courses and multifunctional parks is 150 and 68,respectively.Except for the Pielou evenness index of tree layer,other diversity index in golf course are higher than those in multifunctional park,and there is significant difference in species community composition(Jaccard heterogeneity index up to 0.875,and Bray Curtis heterogeneity index up to 0.778).It is suggested to increase the proportion of native species in multifunctional parks for improving their landscape feature.And the golf courses should be built with the services an functions of native plant community such as biodiversity.
