摘　　要：研究了垂柳1 a生幼苗秋季84 d在TN浓度含量分别为2.03、0.04、0.0和80.0 mg/L,TP浓度分别为0.4、8.0、15.0和25.0 mg/L的模拟富营养化污水中的生长状况、形态变化,及其对不同浓度富营养化水中的总氮、总磷的净化效果。结果表明:垂柳对富营养化水适应性较强,在各种浓度的富营养化水中生长状况一般至良好,株高、叶片数均有不同的增长,但基径变细,对各组污水中TN、TP均有较好的净化作用,平均去除率分别为15.61%和26.91%,是值得大力推广应用的净化富营养化水中氮磷的湿生树种。The one-year seedlings of Salix babylonica were put in 4 groups of simulated eutrophic water with various concentration of total nitrogen as 2.0,30.0,40.0 and 80.0 mg/L and total phosphorus as 0.4,8.0,15.0,25.0 mg/L during 84-day experiment in autumn,and their morphology changes as well as their removal effect on total nitrogen and total phosphorus in eutrophic water were studied.The results showed that Salix babylonica had rather strong adaptability to the eutrophic water,and they grew as usuall or even better with their height,leaves growing respectively,while the stem diameters grew thinner.They had rather good total nitrogen and total phosphorus removal capacities,and the average uptake rate were 15.61% and 26.91% respectively,showing that Salix babylonica was a very good wetland species to be applied in the eutrophic water.
