摘 要：
[目的]研究凤眼莲残体对城市河道有机物的影响。[方法]监测调查污染河道内凤眼莲死亡前后水体有机污染主要指标的变化,探讨凤眼莲残体对污染河流有机污染的影响。[结果]在调查河段,凤眼莲的腐烂分解主要发生在生长后第2年2～4月,对河流水体的有机污染也主要集中在此期间;凤眼莲残体导致水体高锰酸钾指数(CODMn)、5d生化需氧量(BOD5)略有增加,在4月份各监测点的CODMn、BOD5均达年度最大值;凤眼莲死亡分解对下游虽有一定的影响,但影响并不显著(P>0.05)。[结论]该研究为进一步了解凤眼莲死亡引起的二次污染状况提供参考。

摘 要：
[Objective] The research aimed to study the effects of Eichhornia crassipes remains on the organic mater in urban riverway.[Method] The main indices changes of organic pollution in polluted river before and after the death of Eichhornia crassipes were surveyed.The effects of Eichhornia crassipes remains on the organic pollution in polluted river were discussed.[Result] The investigation indicates that Eichhornia crassipes remains decomposed and polluted water from February to April mainly.It made the value of CODMn and BOD5 increase slightly.The disparity in the content of organic pollution was bigger on March,2004.In April,the value of CODMn got the maximum,and the value of BOD5 got the peak.Moreover,it influenced on the lower reches sightly(P>0.05).[Conclusion] The research provided reference for understanding the second pollution caused by the death of Eichhornia crassipes further.
