摘　　要：主要研究水生植物组合对富营养化水体的净化效果。实验选取苦草、轮叶黑藻、常绿鸢尾、水菖蒲为研究对象,构建沉水和挺水水生植物组合,通过监测水体的总氮、总磷、化学需氧量和溶解氧4个水质指标,研究在室内静水条件下不同水生植物组合群落对富营养化水体的净化效果。结果表明:挺水植物与沉水植物组合净化效率大于单一挺水植物或者沉水植物组合,所以合理地搭配沉水—挺水植物群落能够有效提高对富营养化水体的净化效率,减少水体污染。This paper mainly studies the purification effect of aquatic plant combination on eutrophic water body.In the experiment,Vallisneria natans(Lour.)H.Hara,Hydrilla verticillate,Lris hybrids’Louisiana’and Acorus calamus L.are selected as the research objects to construct a combination of submerged and emergent aquatic plants.By monitoring the four water quality indexes of total nitrogen,total phosphorus,chemical oxygen demand and dissolved oxygen,different experimental data were comprehensively evaluated and analyzed to study the purification effect of different aquatic plant communities on eutrophication water under indoor still water conditions.The results show that the purification efficiency of the combination of emergent plants and submerged plants is greater than that of the combination of single emergent plants or submerged plants,so the reasonable combination of submerged plants and emergent plants can effectively improve the purification efficiency of eutrophication and reduce water pollution.
