以广州市花都区城市绿化为研究对象，运用样方调查法结合地植物学、景观生态学、植物造景等理论与方法，在研究广州市岭南特色植物景观及其植物资源的基础上，筛选出具有花城特色的乡土树种，结果表明：（1）调查共计维管束植物470种，隶属于106科264属。其中蕨类植物13科14属28种，裸子植物3科3属4种，双子叶植物81科215属390种，单子叶植物9科32属48种，其中乡土植物优势种具有地带性、典型性、代表性、适生性；（2）筛选的典型乡土植物群落是岭南地区稳定的顶级群落；（3）城市绿化中应“师法自然”，模拟自然顶级群落，设计人工自然群落，为指导城市绿化建设指明了方向。%The article studies urban green spaces in Huadu, Guangzhou, utilizing combined approaches of Quadrat sampling survey method and a variety of theories from different disciplines such as Geobotany, Forest ecology and Planting design. Based on the study of Guangzhou indigenous flora communities and plant resources, the article identifies the flora types and unique indigenous tree species that reflect the characteristic of Lingnan district. The conclusions providing directions for urban green space planning drawn from the study are: (1) Among 93 families, 238 genera and 442 species of Guangzhou native seeding plants, there are 203 genera of tropical distribution that take up 85.29% of the total plant genera (excluding world distribution), which reveals the native flora community in Lingnan district has a strong tropical identity; (2) The identified representative endemic flora communities are the most stable climax community in Huadu, Guangzhou; (3) The identified dominant indigenous tree species are zonal, typical, representative and adaptable.(4) Urban green space planning should follow the principles of nature such as to design artificial plant communities based on the natural climax communities.
