广州城市公园中水生植物景观群落的特征和营造

水生植物群落是园林水体建设必不可少的元素 , 是充分发挥水体生态功能和景观效果的重要 保障。通过选取广州市以水体为主的 7 家代表性城市公园 , 采用实地调查，获取 66 个水生植物群落有效 数据。通过调查法和观察法，研究分析物种组成、群落结构、外貌特征和景观效果。得出广州水生植物 群落以单层结构挺水植物群落为主，呈挺水 - 挺水植物带环带状分布规律。存在类型单一、群落结构简 单、层次分化不明显的问题。提出应从整体生物群落的建设考虑植物群落的配置 , 并根据植物的生活型、 体量特征和结构 , 合理搭配水生植物以丰富群落多样性和结构 , 为优化水生植物群落景观的营造提供参考 依据。

Study on the Community Characteristics and Constructions of Aquatic Plants in Guang

The aquatic plant community is an essential element for the construction of garden water bodies landscape, and is an important part for giving full play to the ecological functions and landscape effects of water bodies. 7 representative urban parks with large water body area in Guangzhou were selected in this study. By field surveys we obtained the species composition, appearance structure and landscape effect of the aquatic plant community in the 7 parks. The existing rules and problems of the aquatic plant community were found out. It is suggested that the land-scape construction of aquatic plant community should be improved from 2 aspects including comprehensive planning of the allocation of aquatic plant, and reasonable ecological niche.
