摘　　要：苏州拥有丰富的湖泊和湿地资源,水体生物修复一直备受关注。在碳达峰碳中和背景下,水体的温室气体排放也受到重视。不同的生物修复方案,其水体修复效果不同,对温室气体排放的影响也不同。以苏州东太湖生态园为研究地,研究两种水体生物修复方案,即以黄花菱为主体的方案(方案L)和以荷花为主体的方案(方案N),对太湖水水质及温室气体排放的影响。研究表明:两种方案均降低了湖水中的TN,TP和COD,方案N表现更佳;两种方案均降低了水体的温室气体排放,方案N的CO_(2)排放量较低,但两种方案在CH_(4)的减排贡献相同;在苏州地区,方案N具有更好的水体净化和温室气体减排效果。Suzhou is rich in lakes and wetlands,and water bioremediation has always attracted much attention.At the same time,in the context of"Carbon Peak,Carbon Neutral",the greenhouse gas emissions of water bodies are also paid attention to.Different bioremediation schemes have different water restoration effects and different impacts on greenhouse gas emissions.In this study,the East Taihu Ecological Park in Suzhou was selected as the research site to study the effects of two water bioremediation schemes,the scheme L with Ludwigia sedioides as the main body and the scheme N with Nelumbo nucifera as the main body,on the water quality and greenhouse gas emissions of Taihu Lake.It showed that both schemes reduce the total N,total P and COD in lake water,and scheme N performs better.Both schemes have reduced greenhouse gas emissions from water bodies,with scheme N having the lowest CO_(2) emissions,but both schemes have the same contribution to CH_(4) emissions reduction.To sum up,in Suzhou area,scheme N has better water purification effect and greenhouse gas emission reduction effect.
