深圳市公园绿地植物配置

摘要

采用分层随机抽样结合典型抽样的方法,对深圳市40个公园绿地的植物配置现状进行调查.结果显示:深圳市公园绿地应用的园林植物种类达到596种,隶属于121科,其中应用频度最高的乔、灌、草、藤分别为凤凰木(Delonix regia)、光叶子花(Bougainvillea glabra)、蜘蛛兰(Hymenocallis americana)、蔓马缨丹(Lantana montevidensis);物种丰富度指数超过3的植物群落占调查总数的20%,植物群落的Simpson指数和Shannon-Wiener指数变化趋势基本相同,不同群落的均匀度指数有明显差异;对不同空间的8种典型植物群落进行了配置分析,总结了深圳市公园绿地植物应用及配置的特点.%A survey on landscape plant arrangement was carried out in 40 parks of Shenzhen City by the method of stratified sampling combined with random sampling. Results show that a total of 596 plant species of 121 families are recorded in the parks, and the high frequency applications of arbor, shrub, herbage and vine species are Delonix regia, Bougainvillea glabra, Hymenocallis americana, Lantana montevidensis respectively. Plants communities whose specie richness is more than 3.0 account for 20％ of all the investigated plant communities. There are unobvious difference in Simpson' s diversity index and Shannon-Wiener diversity index and a significant difference in Pielou' s evenness index between different plant communities. The landscape plant arrangement in eight typical plant communities is analyzed, and the characteristics of application and arrangement of landscape plants in the parks of Shenzhen are discussed.
