| 值、多样性及三维绿量等特征值。结果表明：黄埔村植物资源比较丰富，共有 84 科 194 属215 种，且乔木灌木草本数量配置均匀，但藤本应用较少；其中乔木优势种以小叶榕 Ficus microcarpa、黄葛树 Ficus virens、木棉 Bombax ceiba 等为主，灌木以鹅掌藤 Schefflera arboricola、桂花 Osmanthus fragrans、狗牙花 Ervatamia divaricata 等为主，草本以南美蟛蜞菊 Sphagneticola trilobata、银边山菅兰Dianella ensifolia、芭蕉 Musa basjoo 等为主。该村植物观赏多样性与季相多样性表现良好，但生活型多样性指数较小，仅为 0.697 2；景观空间类型缺乏水平郁闭景观空间的营造。该村植物景观三维绿量分布以乔木占绝对优势，单位面积绿量整体较低且分布不均，它与乔木盖度、植物数量、灌木数量的相关系数分别为 0.849、0.805、0.794。 |

| Abstract: |
| Huangpu village, one of the ancient villages of Guangzhou city, has been taken for the research project in this paper. Based on the field investigation and measurement of plant resources of the village, the important value, diversity and tridimensional green biomass of the plant landscape were calculated and evaluated. The results show as follow: there are about 84 families, 194 genera and 215 species plant resources of landscape in Huangpu village, the proportion amount of their arbors, shrubs and herbs were uniformity. But the application of lianas is less. As to the amount totally, the mainly dominant species of arbor were of Ficus microcarpa, Ficus virens, Bombax ceiba, and the mainly dominant species of shrubs were of Schefflera arboricola, Osmanthus
fragrans, Ervatamia divaricata, while that of mainly herbage were of Sphagneticola trilobata, Dianella ensifolia, and Musa basjoo. The diversity of ornamental plants and seasonal appearance of plants has performed better. However, the diversity index of life forms was small, its numerical only 0.697 2. In terms of landscape space types of this village has lacked the type of horizontal closure. Which of that, the arbor has talked the absolute dominant in the distribution of tridimensional green biomass of plant. The green biomass of the unit area was less, unevenly distributed, and positively correlated with arbor coverage, numbers of plants, as well as numbers of shrubs. The correlation coefficients are 0.849, 0.805 and 0.794 respectively. |
