摘　　要：[目的]研究多种环境因子及其交互作用对水生植物复氧的影响。[方法]采用不同种类水生植物对实施环境调控后水生植物复氧能力的响应情况进行考察,研究主效环境因子之间交互作用产生的影响,从而解析不同种类水生植物复氧变化规律。[结果]黑藻、荇菜和香蒲响应面模型方程中一次项和二次项影响较为显著,试验中因素与响应值之间的影响是较为复杂的线性关系。单个因素对黑藻、荇菜和香蒲的复氧能力值(OE)影响顺序分别为p H>光照(L)>盐度(S)>温度(T),S>L> p H>T,L>S>pH>T。根据响应面二次模型可得到3种水生植物环境因子优化方案,黑藻优化方案为:L为10 159 lx、T为21℃、p H为7.69,S为0.10%,在上述优化条件下,黑藻OE值为58.72;荇菜优化方案为:L为11 956 lx、T为26℃、p H为7.5,S为0.12%,在上述优化条件下,荇菜OE值为46.32;香蒲优化方案为:L为12 000 lx、T为21℃、p H为7.14,S为0.11%,在上述优化条件下,香蒲OE值为59.22。[结论]该研究为臭水体水生植物光合作用复氧技术研究提供依据。[Objective]The research aimed to study the effects of various environmental factors and their interactions on reoxygenation of aquatic plants.[Method]The response of different types of aquatic plants to the reoxygenation capacity of aquatic plants after environmental regulation was investigated to study the effects of interactions between major environmental factors,and to analyze the changes of reoxygenation of different aquatic plants.[Result]The effects of primary and secondary terms in the model equations of Hydrilla verticillata,Nymphoides peltatum and Typha orientalis were relatively significant,and the influence between the experimental factors and the response values was a more complex linear relationship.The influence order of single factor on the reoxygenation capacity(OE)of Hydrilla verticillata,Nymphoides peltatum and Typha orientalis was pH>Lighting(L)>Salinity(S)>Temperature(T),S>L>pH>T,L>S>pH>T.According to the response surface quadratic model,three aquatic plant environmental factor optimization schemes could be obtained.The optimization scheme of Hydrilla verticillata was:L was 10 159 lx,T was 21℃,pH was 7.69,S was 0.10%;under the above optimized conditions,the OE value was 58.72.The optimization scheme of Nymphoides peltatum was:L was 11 956 lx,T was 26℃,pH was 7.5,S was 0.12%;under the above optimized conditions,the OE value of Nymphoides peltatum was 46.32;the optimization scheme of scheme was:L was 12 000 lx,T was 21℃,pH was 7.14 and S was 0.11%.;under the above optimized conditions,the cattail OE value was 59.22.[Conclusion]The study provides the theoretical basis for the monitoring of the water environment.
