摘　　要：以广州市的10个城市公园、10条城市干道和10个居住区为研究对象,应用实地分区抽样法,调查和记录所属区内出现的杜鹃花属植物种类、出现频率、配置方式和生境特点。结果表明,广州市绿地露地中应用的杜鹃花属种类常见的有锦绣杜鹃(Rhododendron pulchrum)和凤凰杜鹃(R.pulchrumvar.phoeniceum),偶见种为映山红(R.simsii)和皋月杜鹃(R.indicum);毛白杜鹃(R.mucronatum)本次调查未见,盆栽植物主要有西洋杜鹃(R.hybridum)。杜鹃花属植物在公园露地应用较广,居住区有少量应用,但道路绿化带应用极少。公园、居住区的应用方式较为多样,花期时的观赏效果甚佳。文章简要评价了广州部分以杜鹃花为配置材料的景观特点,并分析了杜鹃花属植物在广州市绿化应用中的优势及存在的问题;提出加强野生杜鹃花的引种驯化和杜鹃花属植物的抗逆性选育种研究,促进乡土杜鹃花种类的驯化和应用的建议。Plants of Rhododendron, with their beautiful flowers, are one of the traditional famous flowers of China. The species, planting frequency, disposition and habitats of Rhododendron were investigated in 10 public parks, 10 key roads and 10 large residential areas. The result showed that only a few species of Rhododendron were applied in Guangzhou. Of these, Rhododendron pvdchrtun and R. pulchrmn vat. phoemceum were the commonest. R. simsii and R. indacuro were occasionally planted. R. mucronatum was recorded, but not seen. The plants of Rhododendron were widely found in public parks, occasionally seen in residents, but seldom planted in the roadside. The dispositions of Rhododendron were diverse both in public parks and residential areas. Some excellent landscapes with Rhododendron species in Guangzhou were evaluated. The advantages and problems of Rhododendron＇s applications in landscape of Guangzhou were discussed. It is suggested to enhance acclimatization and application of native species of Rhododendron.
