城市滨水地带野境草本植物多样性 与群落结构研究--以福州地区典型水域为例

Due to its advantaged natural conditions, the urban waterfront area had better sense of experience and stronger plasticity in the design of wild plants than other areas. In order to provide basic materials for the construction of waterfront green space landscape with regional characteristics> low maintenance and low consumption, the wild plant communities in the waterfront green space of Fuzhou were investigated and their species composition characteristics were studied. The results showed that there were 66 species of wild herbaceous plants belonging to 62 genera and 31 families in the urban waterfront research area of Fuzhou, among which Gramineae and Asteraceae were the main ones. The proportion of perennial plants was higher than that of 1-year-old and 2-year-old plants, and the native plants were dominan匚 The community characteristics of wild plants in the waterfront areas were summarized, and it was found that the vegetation community structure in the areas with low accessibility tended to be multi-layered and complex, among which the important values of Hydrocotyle sibthorpioides Lam. and Thalia dealbata Fraser were larger. Based on this, the ornamental plants such as Coreopsis ba sails (A. Dietr.)S. F. Blake, Phragmites australis (Cav.)Trin. ex Steud, etc. were sorted out and analyzed. Finally, it. was proposed to promote the natural regeneration ability of wild plants by means of screening & retention, and vegetation management, so as to play the role of wild plants in repairing the grey zone of urban waterfront space.
