摘　　要：采用浮床黑麦草(Lolium multiflorum)对畜禽养殖富营养水体氨氮的净化效应及动态过程进行了研究.结果表明:浮床黑麦草对富营养水体中的氨氮具有明显的净化效果.当覆盖率30%时,对氨氮的去除率最高可达到95.89%.对其去除水体氨氮的动态过程拟合表明符合三次方程曲线.该研究为冬季陆生植物修复富营养水体提供重要依据.The purification effect and dynamics processes of Lolium multiflorum on floating bed for removing ammonia nitrogen in eutrophicated water body were studied. The results showed that Lolium multiflorum could remove ammonia nitrogen effienciently in eutrophicated water body. The removal rates of ammonia nitrogen in water reached 95.89 % when the floating bed coverage was 30%, The fitting method of dynamics processes of removing ammonia nitrogen by Lolium multiflorurn showed it accords with cubic curve, This work suggested that terrestrial plant on floating bed could provide remediation for eutrophicated water bodies effectively in winter,
