以金鱼藻（Ceratophyllum demersum L.）、苦草（Hydrilla verticillata）、黑藻（Vallisneria natans (Lour.) Hara）3种沉水植物作为研究对象，分别将其放置于不同污染水体中培养，通过监测水体总氮、总磷、叶绿素a含量和pH值等，探究不同沉水植物对水质的净化效果；同时通过对植物体内总氮、总磷含量以及超氧化物酶（SOD）、丙二醛（MDA）的变化，研究植物在不同污染水体中的生长情况。结果表明，不同沉水植物对不同污染水体的净水效果有着显著差异，不同污染水体的胁迫作用对沉水植物本身的生理生长也有着不同的影响。综合所研究的沉水植物的净水优势以及在不同污染水体中的适应情况，筛选出在各种污染水体中的优势种，归纳总结出生态修复组合的方案。

In this paper, three submerged plants (goldfish algae(Ceratophyllum demersum L.), bitter grass(Hydrilla verticillata)and hydrilla(Vallisneria natans (Lour.) Hara)) were chosen as the research object and placed in different polluted water to explore different submerged plant’s purification effect on the water quality by monitoring water’s total nitrogen, total phosphorus. chlorophyll a content, and pH, etc. At the same time, based on the total nitrogen and total phosphorus content in plant and superoxide enzyme (SOD), malondialdehyde (MDA), the growth of the plants in different polluted water was researched. The results showed that the purification effects of different submerged plants have a significant difference on different polluted water, and the stress of different polluted water on the physical growth of submerged plant also has different effects.
