| 中文摘要: |
| 营造生态效益与景观效果俱佳的园林景观，是园林建设的核心与难点。从群落结构和植株观赏效果两方面对广州市生态景观林带植物的现状进行了统计分析，包括乔木层和灌木层的密度、覆盖度、丰富度，及树种的观赏期、观赏色彩、树形。结果显示，目前林带存在物种丰富度低、部分群落过密覆盖度过高、夏秋冬3 季可赏树种较少等问题。参照广州市地带性植被物种组成和群落结构，提出林带树种选择和群落构建的优化建议。 |
| 英文摘要: |
| Creating a landscape that is both ecologically and visually excellent is essential to landscape design, and also the difficulty of it. We analyze the status of eco-landscape forest belt in Guangzhou in the aspects of community structure and ornamental effect using statistical methods, including the density, coverage, richness of both tree and shrub layer, and ornamental period, colour and form of the trees. The results show that problems existing in current forest belt include low species diversity, regional overcrowding and scarcity of ornamental species in summer, autumn and winter. We provide suggestions for choosing tree species for forest belt and optimization of community structure with reference to regional vegetation assemblage and community structure in Guangzhou. |
