摘　　要：针对受强台风"达维"侵袭之后,海南省儋州地区常用的10种园林乔木,进行受损情况分级打分并以各树种的得分为参考数据列,以树高、胸径、枝下高和冠幅作为抗风性能分析评价指标,采用灰色关联分析方法对树种的自身指标因素与其抗风性能的关系进行分析。研究结果表明:树种的自身指标因素与其抗风性能的关联度大小依次为:胸径>树高>冠幅>枝下高;10种园林乔木的抗风能力,大王棕、黄葛榕、小叶榕、樟树、油棕、桃花心木和凤凰木较强,伊朗紫硬胶中等;羊蹄甲与印度紫檀较差。It is necessary to select ornamental tree species with stronger wind-resistance ability, especially in those areas with typhoon attacking frequently. Taking 10 common landscaping tree species in Danzhou , Hainan Province, graded and built data column depending on damaged scores of each species, carried the wind- resistance analysis depending on 4 indicators including tree height, diameter breast-high（DBH）, under branch height and crown width, and took the Grey association analysis to explore the relations between the wind resistance and tree indicators after strong typhoon ＂ Dawei＂ attack. The result showed that the rank of the relational extent between the tree indicators and wind resistance as follows： DBH〉height〉crown width〉under branch height. For wind resistant ability of 10 species, Roystonea regia, Ficus microcarpa, Ficus microcarpa, Cinnamomum camphora, Elaeis guineensis, Khara senegalenss and Delonix regia are strong, Mimusops elengi is medium, Bauhinia purpurea and Pterocarpus indicus are poor.
