在园林绿化建设中,水池、溪流,以及水面边沿等地带,需要选用湿生的耐湿性较强的地面覆盖植物,用来美化环境和点缀景观,兼能防止和控制杂草危害水体,并能有效防止土壤中的有机物被雨水冲刷带入水体中,减少水体富营养程度。景观水域种植水生植物除了景观需要外,一个重要的的目的是为了利用水生植物吸收水体的氮磷等营养物质,从而来控制及改善水体的富营养化状况。水体中与富营养化有关的因子有氮、磷、COD、透明度、叶绿素a或浮游生物量、DO、SS等,其中氮、磷
In landscaping, ponds, streams, and the waterfront and other areas need to select wet-growing wet-resistant ground cover plants that can be used to beautify the environment and decorate the landscape, and to prevent and control weeds that endanger the water body, and can Effectively prevent the organic matter in the soil from being washed into the water by the rainwater and reducing the degree of eutrophication of the water body. Aquatic Planting in Landscape Waters In addition to landscape needs, an important objective is to control and improve eutrophication of aquatic organisms by using aquatic plants to absorb nutrients such as nitrogen and phosphorus. Among the factors related to eutrophication in water, nitrogen, phosphorus, COD, transparency, chlorophyll a or plankton biomass, DO, SS and so on, of which nitrogen and phosphorus
