摘　　要：人工湿地以生态、低耗、经济、稳定等优点,被广泛应用于污水处理和生态修复等领域。人工湿地在去除污染物的同时,也伴随着CO_(2)、CH_(4)和N_(2)O等温室气体的产生和释放,可能导致其生态环境效益降低。介绍了不同类型人工湿地温室气体的排放特征及其机制,总结了植物、基质、构型、进水负荷、运行方式和季节等对温室气体排放通量的影响,最后提出了人工湿地温室气体减排措施及未来研究方向。Artificial wetlands are widely used in sewage treatment and ecological restoration due to their ecological benefits,low resource consumption,cost-effectiveness,and stability.While removing pollutants,artificial wetlands also produce and release greenhouse gases such as CO_(2),CH_(4) and N_(2)O,which may reduce their ecological and environmental benefits.This paper introduces the characteristics and mechanism of greenhouse gas emissions from different types of artificial wetlands,and summarizes the effects of various factors such as plant types,substrates,configuration,influent loads,operation modes and seasonal variations on emission fluxes.Additionally,we offer emission reduction measures and propose future research directions.
