湿地植物在农业面源污染防治中的应用研究进展

An Overview of Wetland Plants Applied to Agricultural Non-Point Source Pollution Treatment

湿地植物作为湿地生态系统中主要的建群种类,能有效吸收和去除水体中的氮、磷等富营养物质,在农业面源污染防治中应用广泛。本文结合国内外研究,综述了适用于农业面源污染防治的湿地植物,并对其氮、磷、有机物的去除效果进行了比较。从应用及配置方法上,论述了湿地植物选择和优化配置对农业面源污染防控和农田区域生态恢复的意义,以期为农业面源污染净化工程中湿地植物的设计应用提供决策依据和技术支持,并对今后的研究方向提出建议。

As the main groupspecies in the wetland ecosystem, wetland plants can effectively absorb and remove eutrophic materials such as nitrogen and phosphorus in water, and are widely used in the prevention and control of agricultural non-point source pollution. Based on the existing research data at home and abroad, this paper reviews the wetland plants commonly used in the prevention and control of agricultural non-point source pollution, and the effects of TN, TP and COD removal are compared.The significance of wetland plant selection and optimal allocation for agricultural non-point source pollution prevention and control and farmland regional ecological restoration is discussed from the point of view of application and allocation methods. In order to provide decision-making basis and technical support for the design and application of wetland plants in agricultural non-point source pollution purification project, some suggestions for future research direction are put forward.
