摘　　要：研究了优势菌对富营养化景观水体修复作用。结果表明,投加优势菌4 d后出现修复效果,20 d修复效果达到最佳状态,浊度、NH3-N、CODMn、TN、TP和叶绿素a都大幅下降,溶解氧从7.2 mg/L提高到10.4 mg/L,叶绿素a与CODMn、TN、TP、NH3-N有较好的相关性。The restoration efficiency of dominant bacteria on the eutrophic landscape water was investigated. The experimental results showed that the restoration effect appeared 4 days later and got the best condition 20 days later. CODMn, NH3-N, turbidity, TN, Tp and Chl-a decreased rapidly and DO was improved from 7.2 mg/L to 10.4 mg/L. Chl-a related well to TP,CODMn ,TN.
