[目的]研究在人工模拟的微型生态系统中，不同水生植被下的污水中环棱螺的生存状况。[方法]通过模拟冬季不同植被湿地条件，检测污水对太湖环棱螺（Bellamya sp．）超氧化物歧化酶（SOD）、丙二醛（MDA）活性及其存活率的影响，探究不同大型湿地水生植物模型条件下太湖环棱螺的生存状况。[结果]在不同水生植物建立的湿地模型中，从环棱螺的存活率来看，水花生组显著高于其他组。芜萍组存活率最低；环棱螺的SOD活性均为先降后升的趋势；MDA活性的变化趋势有所差异，芜萍组、灌木柳组和对照组为先升后降，最后趋于一致，而金鱼藻组和水花生组无明显变化，水芹菜组变化比较复杂。[结论]在冬季的5种水生植被环境中，水花生与环棱螺的组合对富营养化污水有明显的抵御效果，而芜萍与环棱螺的组合效果最差。

[Objective] The aim was to explore living conditions of Bellamya sp. in polluted water with aquatic vegetation in different varieties. [Method] With wetland in winter simulated, effects of polluted water on SOD, MDA and survival rate of Bellamya sp. were researched to further study living condition of Bellamya sp. in wetlands at scale with aquatic vegetation. [Result] According to simulation, Altemanthera philoxeroides was highest in survival rate and Wolffia arrhiza was the lowest; SOD activity of Bellamya sp. changed from decreasing to increasing; MDA activities changed from increasing to decreasing in groups of Wolffia arrhiza, Salix saposhnikovii and control group and changed little in group of Ceratophyllum demersum and Alternanthera philoxeroides. The changes of MDA in group of Oenanthe stolonifer proved much more complicated. [Conclusion] Of the aquatic environment with five varieties of aquatic vegetation, combined group of Alternanthera philoxeroides and Bellamya sp. was of significant resistance against eutrophication, and the group of Wolffia arrhiza and Bellamya sp. proved with poorest in resistance.
