摘　　要：研究了浮水植物槐叶萍(Salvinia natans)在两种富营养化水体中的生长状况及不同生物量的槐叶萍对富营养化水体的净化效果.结果表明,槐叶萍生物量的增长在轻度富营养化水中高于在重度富营养化水中,对轻度富营养化水体的净化效果远高于对重度富营养化水体的净化效果,在轻度富营养化水体中生长最好.不同生物量的槐叶萍对水体的净化效果没有显著性差异.The growth situation of Salvinia natans, a float plant, in two types ot eutrophicate water, and purifying effect of different biomass of Salvinia natans in eutrophicate water were studied. The experiments results indicated that the biomass growth and puriflying effect of Salvinia natans in low degree eutrophicate water is higher than that in high degree eutrophicate water, and it grows best in former. The puriflying effect of different biomass of Salvinia natans in eutrophicate water had no apparent difference.
