中文摘要：选取西南常见的挺水植物水蓑衣(Hygrophila salicifolia)、梭鱼草(Pontederia cordata)和鸢尾(Iris tectorum),浮水植物睡莲(Nym-phaea tetragona)和水鳖(Hydrocharis dubia),及沉水植物金鱼藻(Ceratophyllum demersum)、狐尾藻(Myriophyllum verticillatum)和苦草(Val-lisneria natans)为对象,通过室内模拟探讨其去除水体富营养化的效果.结果表明,经过30d处理,8种植物对富营养化水体均有不同程度的净化作用.其中,水蓑衣对总氮、总磷、化学需氧量、氨氮去除效果最好,去除率分别为49.80%、31.34%、41.05%和45.22%,苦草和狐尾藻次之,金鱼藻和水鳖较差.因此,水蓑衣和苦草是去除城市景观水体富营养化污染的潜在园林植物.

外文标题：Purification Effects of Aquatic Plants in Eutrophic Wetlands Under the Background of Carbon Neutrality

外文摘要：This study selected common aquatic plants in the Southwest region,namely Hygrophila salicifolia,Pontederia cordata,Iris tectorum,Nymphaea tetragona,Hydrocharis dubia,Ceratophyllum demersum,Myriophyllum verticillatum and Vallisneria natans.These plants were subjec-ted to indoor simulations to investigate their effectiveness in mitigating eutrophication in water bodies.The results showed that after 30 days of treatment,all eight plant species exhibited varying degrees of purification effects on eutrophic water bodies.Among them,H.salicifolia showed the best removal efficiency for TN,TP,COD and NH4+-N,,with removal rates of 49.80%,31.34%,41.05%,and 45.22%,respectively.V.na-tans and M.verticillatum followed,C.demersum and H.dubia exhibited relatively lower purification effects.Therefore,H.salicifolia and V.natans were considered potential landscaping plants for removing eutrophication pollution in urban landscape water bodies.
