摘　　要：为了实现人工湿地全年稳定高效的运行目标,在分析低温环境对人工湿地系统运行效果的影响的基础上,探讨了一系列强化措施,通过合理的植物配置、生物强化、基质选择、覆盖保温和增加水中溶解氧等措施,改善了人工湿地的净化能力。研究结果表明,这些措施能够提升湿地的生态多样性和生物量,并提高湿地系统的降解能力。提出了未来应在深入水体净化机理的基础上,分析宏观和微观之间的联系,加强对湿地系统运行机制的理解,以期为人工湿地在北方寒冷地区的应用和推广提供参考。In order to achieve the goal of stable and efficient operation of the constructed wetland throughout the year,a series of strengthening measures were discussed based on the analysis of the influence of low temperature environment on the operation effect of the constructed wetland system.The purification capacity of the constructed wetland was improved through reasonable plant configuration,biological enhancement,substrate selection,covering insulation and increasing dissolved oxygen in water.The results show that these measures can improve the ecological diversity and biomass of wetlands,and improve the degradation capacity of wetland systems.It is proposed that the relationship between macro and micro should be analyzed on the basis of in-depth water purification mechanism in the future,so as to strengthen the understanding of the operating mechanism of wetland system,in order to provide reference for the application and promotion of constructed wetlands in the cold areas of north China.
