摘　　要：人工湿地具有良好的PPCPs去除效能,湿地植物在其中发挥了重要作用,大多数已发表的综述研究均集中在填料和微生物的作用上,缺乏湿地植物对PPCPs去除机制的报道。本研究系统总结了人工湿地植物在PPCPs去除中的作用,包括植物根系的吸收和降解、为微生物提供适宜的定殖环境以及通过植物根系分泌物塑造根际微生物群落,增强PPCPs的去除效率。文章解析了人工湿地植物去除PPCPs的影响因素,包括温度、氧化还原电位和pH值等,并提出了未来的研究可集中于湿地植物的不同组织对PPCPs的去除作用以及量化每个组织的贡献率,这对于全面揭示人工湿地对PPCPs的去除机制具有重要意义。Constructed wetlands have good efficiency in removing PPCPs,with wetland plants playing an important role in this process.However,most published reviews focus on the role of substrates and microorganisms,lacking reports on the removal mechanisms of wetland plants for PPCPs.Therefore,this study systematically summarizes the roles of constructed wetland plants in PPCPs removal,including absorption and degradation by plant roots,providing suitable colonization environments for microorganisms,shaping rhizosphere microbial communities through root exudates,and enhancing the efficiency of PPCPs removal.This review further analyzes the influencing factors of constructed wetland plants in removing PPCPs,including temperature,redox potential,pH,etc.,and proposes that future research can focus on the removal effects of different tissues of wetland plants on PPCPs and quantify the contribution of each tissue,which is of great significance for comprehensively understanding the removal mechanism of constructed wetlands on PPCPs.
