摘要
为使城市整体质量提升,人居环境优美,以广州市越秀公园为研究对象,运用心理物理学派美景度测量与调查方法——美景度评价法,选取10个代表性植物群落进行景观美学质量评价,运用多元线性回归建立景观美景度与植物群落结构间的数量化回归模型,解析影响植物景观美景度的关键因子。结果表明:榕树+木棉+彩叶灌木、棕榈类+地被等群落有较高的美景度得分值。影响植物景观美景度的关键要素有植物本身形态特征、草坪覆盖度、遮阴效果等。提高乡土乔木树种多样性和植物色彩丰富性,是改善城市公园森林植物景观的可行途径。
To improve the quality of overall urban area and human settlement environment, 10 representative plant communities in Yuexiu Park in Guangzhou were selected to conduct an evaluation on landscape aesthetic quality using scenic beauty estimation（SBE）. Multiple linear regression method was used to establish thequantitative regression model between scenic beauty and plant community structure, then key elements of landscape beauty degree were analyzed. The results showed that Ficus microcarpa ＋ Bombax malabaricum ＋colored shrubs, Trachycarpus fortunei ＋ ground cover community had high scores of scenic beauty. The keyelements affecting the degree of scenic beauty included plant morphological characteristic, grass coverage,shade effect, etc. Promoting the diversity of local tree species and other plants will be a feasible way to improve the plant landscape of urban park.
