摘　　要：研究了菰〔Zizania latifolia(Griseb.)Stapf〕、菖蒲(Acorus calamusL.)及它们的复合体系对富营养化水体的净化效果。结果表明,菰和菖蒲在供试富营养化水体中均能正常生长,二者单独种植体系或等量混合种植体系对富营养化水体均有一定的净化能力。单独种植的菰和菖蒲及二者的混合种植体系对供试水体中总氮的去除率分别为92.8%、92.7%和94.9%;对氨氮的去除率分别为95.5%、97.4%和96.6%;对总磷的去除率分别为83.9%、94.3%和84.7%;对CODCr的去除率分别为83.0%、85.5%和86.7%。单独种植的菖蒲对总磷的去除效果明显好于单独种植的菰和二者的混合种植体系。菰和菖蒲的混合种植体系对富营养化水体的净化效果与单独种植体系无明显差异。The purification efficiencies of Zizania latifolia （Griseb.） Stapf, Acorus calamus L. and their complex system to eutrophic water were studied. The results showed that both Z. latifolia and A. calamus could grow well in eutrophic water. The removal rate of TN by monoculture and complex system of Z. latifolia and A. calamus was 92.8%, 92.7% and 94.9% respectively, and that of NH3-N, TP, CODCr was 95.5% ,97.4% ,96.6% and 83.9% ,94.3% ,84.7% and 83.0% ,85.5% ,86.7% respectively. The monoculture system of A. calamus had greater effects on purifying TP than monoculture system of Z. latifolia and the two species complex system. There was no evident difference of purification efficiency to eutrophic water between complex system of the two species and monoculture system.
