摘　　要：湿地植物是人工湿地系统的重要组成部分,在污染物去除方面发挥重要作用。人工湿地植物收割可以有效去除植物吸收的氮、磷、COD、TOC等污染物,防止植物枯萎进入水体导致湿地水体二次污染。植物收割还可以促进植物再生长,增强植物对污染物吸收效率。本文介绍了人工湿地植物收割对人工湿地系统污水净化、微生物数量丰富度变化以及植物再生长的整体影响。深入分析了湿地植物收割后人工湿地系统的自我调节,为采用不同策略收割人工湿地以提高湿地功能的研究和应用提供了参考。Wetland plants are an important part of constructed wetland system and play an important role in pollutant removal.Plant harvesting in constructed wetlands can effectively remove nitrogen,phosphorus,COD,TOC and other pollutants absorbed by plants,and prevent plants from wilting into the water and causing secondary pollution of wetland water.Plant harvesting can also promote plant regrowth and enhance the absorption efficiency of pollutants.This paper introduces the effects of plant harvesting on sewage purification,microbial abundance and plant regeneration in constructed wetland system.The self-regulation of the constructed wetland system after the harvest of wetland plants was deeply analyzed,which provided a reference for the research and application of different harvesting strategies to improve the function of the constructed wetland.
