摘要
人工湿地是一种被广泛使用的新型污水处理技术。笔者阐述了构建人工湿地常用的水生植物种类及根系类型,从根系生物量及其变化研究、根系分布及根系表面积研究两方面综述了湿地水生植物根系生长情况的研究现状;从水生植物根系去除污染物的研究、水生植物根系泌氧的研究两方面综述了水生植物根系对湿地水体净化作用的研究现状,并对该领域今后的发展提出了一些思考和展望。
Constructed wetland was a new kind of wastewater treatment technology which was widely used. In this paper, the species and root types of common aquatic plants in constructed wetlands waselaborated. Research status of aquatic plant root growth situation in wetland was reviewed from root biomass and its changes, root distribution and root surface area 2 as- pects. And its purification function to wetland water were expounded removal pollutants for aquatic plants and oxidization of aquatic plants 2 aspests. Some thoughts and expectations on the development in this field were put forward.
