摘　　要：研究比较了三角帆蚌(Hyriopsis cumingii)底播和悬挂2种放养方式对富营养化水体的净化效果。结果表明,三角帆蚌的2种放养方式能够显著降低富营养水体中的总氮(TN)、悬浮物(TSS)、化学需氧量(CODCr)和叶绿素a(Chla),但是对总磷(TP)的净化效果不显著;2种放养方式之间的净化效果差异不显著。Hyriopsis cumingii’s purifying effect was compared between upper and bottom stocking.The results indicated that Hyriopsis cumingii’s upper and bottom stocking can significantly reduce(P<0.05)the total nitrogen(TN),the total suspended substance(TSS),chemical oxygen demand(COD)and chlorophyll a(chla),but the removal efficiency of total phosphorus(TP)was not signif⁃icant.The removal efficiency of eutrophic water was not significant between upper and bottom stocking.
