湿地植物对人工湿地生态修复作用研究

该文从人工湿地的类型与湿地植物净化效果的研究讨论,分别从季节性显著及注重场地条件等角度等提出在人工生态修复中植物运用的特点。人工湿地中的超富集植物在乡村振兴中具有巨大的开发潜力,如用于农业面源污染治理、当做牲畜草料饲料、自然新陈代谢产物用作泥炭土,次生代谢产物提取精油等。人工湿地也非常适合中小城乡的污水处理,利用生态塘、生态沟渠、农田生态廊道等手段合理使用人工湿地植物治理农业面源污染,值得相关人员继续深入研究。

Based on the research and discussion on the types of constructed wetlands and the purification effect of wetland plants,this paper puts forward the characteristics of plant application in artificial ecological restoration from the point of view of seasonality and paying attention to site conditions.The super-enriched plants in constructed wetlands have great po-tential for development in rural revitalization,such as agricultural non-point source pollution control,as livestock forage,nat-ural metabolites as peat soil,secondary metabolites to extract essential oils and so on.Constructed wetlands are also very suitable for sewage treatment in small and medium-sized urban and rural areas.The rational use of constructed wetlands plants to control agricultural non-point source pollution by means of ecological ponds,ecological ditches and farmland ecolog-ical corridors is worthy of further study.
