摘  要：
以紫叶酢浆草(Oxalis triangularis)、凤眼莲(Eichhornia crassipes)和大漂(Pistia stratiotes)为试验对象,研究了其生长状况及对3种不同富营养化水体的净化效果,分析了3种水生植物对水体中总磷、总氮和氨氮的吸附能力。结果表明,3种水生植物在富营养化水体中可以正常生长。大漂对3种不同富营养化程度水体的总磷吸收率分别为93.58%、97.72%和96.65%,紫叶酢浆草为89.57%、83.76%和86.54%,凤眼莲为90.11%、85.07%和91.46%;大漂对水体中总氮的吸收率分别为89.05%、90.18%和73.50%,紫叶酢浆草为68.32%、59.73%和72.90%,凤眼莲为68.45%、71.49%和71.53%;大漂对氨氮的吸收率为85.80%、91.48%和88.60%,紫叶酢浆草为77.51%、72.07%和89.68%,凤眼莲为68.84%、90.90%和90.88%。试验表明,3种水生植物均能显著改善富营养化水体的水质。各项指标综合分析可见,大漂对富营养化水体的净化效果最为明显,凤眼莲次之。

摘  要：
With Oxalis triangularis,Eichhornia crassipes and Pistia stratiotes as the planting stuff,studied their growth status and the purification effect on the three differents eutrophic water,and investigated their capability to remove total phosphorous(TP),total nitrogen(TN) and ammonia nitrogen(NH3-N).The results showed that three kinds of hydrophytes in eutrophic water can normally grow and develop.The removal rate of TP respectively reached 93.58%,97.72%,96.65% by Pistia stratiotes,89.57%,83.76%,86.54% by Oxalis triangularis,90.11%,85.07%,91.46% by Eichhornia crassipes;the results of removal efficiency for TN respectively reached 89.05%,90.18%,73.50% by Pistia stratiotes,68.32%,59.73%,72.90% by Oxalis triangularis,68.45%,71.49%,71.53% by Eichhornia crassipes;The removal efficiency for NH3-N respectively reached 85.80%,91.48%,88.60% by Pistia stratiotes,77.51%,72.07%,89.68% by Oxalis triangularis,68.84%,90.90%,90.88% by Eichhornia crassipes.The experiments proved the three kinds of hydrophytes can abviously improve the quality of the eutrophic water.The integrated analysis of all indices indicate that in different eutrophic water,the purification effect of Pistia stratiotes was the best,Eichhornia crassipes take second place.
