摘　　要：通过实地调查,研究陆河县建成区园林木本植物应用情况。结果表明:陆河县建成区园林木本植物共计221种(包括种下单位)。其中本地木本植物共计209种,隶属62科156属,本地木本植物指数为0.95。基调树种有樟(Cinnamomum camphora)、火焰木(Spathodea campanulata)、秋枫(Bischofia javanica)等,骨干树种有阴香(Cinnamomum burmannii)、鸡蛋花(Plumeria rubra‘Acutifolia’)、槭叶瓶干树(Brachychiton acerifolius)等,应用频率较高的木本植物有阴香、四季桂(Osmanthus fragrans var.semperflorens)、樟等。生活型分析显示,陆河县建成区应用于园林绿化的乔木有126种,占57.0%;灌木有共87种,占39.4%;木质藤本植物8种,占3.6%。观赏特性分析结果显示,陆河县园林木本植物主要以常绿木本植物为主,种类指数为0.60~0.94;其次为观花木本植物,种类指数为0.10~0.50;观叶木本植物最少,种类指数为0.05~0.20。The woody landscape plants used in the built-up areas of Luhe County were studied by field investigation.The results showed that there were 221 species of woody plants in the built-up area of Luhe County.Among them,there are 209 species of native woody plants,belonging to 62 families and 156 genera,with a local woody plant index of 0.95.The base tree species include Cinnamomum camphora,Spathodea campanulata,Bischofia javanica,etc.,the backbone tree species include C.burmannii,Plumeria rubra‘Acutifolia’,Brachychiton acerifolius,etc.,and the woody plants with higher frequency of application include C.burmannii,Osmanthus fragrans var.semperflorens,C.camphora,etc.The analysis of life forms shows that there are 126 species of trees used for landscaping in the built-up areas of Luhe County,accounting for 57.0%;87 species of shrubs,accounting for 39.4%;and 8 species of woody vines,accounting for 3.6%.The analysis results of ornamental characteristics show that the woody plants in Luhe County are mainly evergreen woody plants with a species index of 0.60 to 0.94;followed by woody flowering plants with a species index of 0.10 to 0.50;foliage woody plants are the least with a species index of 0.05 to 0.20.This research could provide a reference for optimizing the structure of landscaping woody plants and improving the level of landscaping in Luhe County.
