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. |
