摘　　要：以上海曲阳公园中心湖水体为研究对象,通过分析其污染成因、污染状况和湖体水质,结合水质改善及景观功能定位,确定中心湖生态修复技术。通过对湖底的生境营造及对水生植物系统、水生动物系统及微生态系统的修复,使水体具备自我净化能力,并维持水中湖生态系统的平衡。研究结果表明,水生态系统建成1年后,中心湖水体透明度、化学需氧量(COD)、氨氮(NH3-N)、总磷(TP)等指标均较构建前有显著改善。该研究结果对城市景观水体的水质改善、生态建设和后期管理均具有一定的指导性意义。Taking Central Lake water of Shanghai Quyang Park as the research object, through analyzing the causes of pollution, pollution and lake water quality, combined with the improvement of water quality and landscape function, the ecological restoration technology of central lake was determined. By creating a lake habitat for aquatic plants and systems, aquatic systems and micro-ecosystem restoration, water bodies have the ability to self-purification, and maintain the balance of aquatic ecosystems. The results showed that aquatic ecosystems completed after one year, the central water transparency, chemical oxygen demand （COD）, ammonia nitrogen （NH3 -N）, total phosphorus （TP） , etc. than before to build a significant improvement. The results of this study have some guiding significance for the improvement of the water quality, ecological construction and later management of the urban landscape water.
