摘　　要：以佛山石湾公园景观湖水体为研究对象,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,确定景观湖生态修复技术。通过对湖底的污染控制、生境营造及对水生生态系统的修复,使水体具备自我净化能力,并维持湖泊生态系统的平衡。研究结果表明,生态修复措施完成后,景观湖水体透明度、化学需氧量、生化需氧量、氨氮、总磷等指标均较修复前有显著改善。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 the landscape lake in shiwan park of foshan as the research object, the ecological remediation technology of the lake was determined by analyzing the pollution causes, pollution situation and water quality of the lake, combining water quality improvement with landscape function orientation. Pollution control, habitat construction and remediation of aquatic ecosystem can make the water have the ability of self-purification and maintain the balance of the lake ecosystem. The results showed that the transparency, chemical oxygen demand(COD), biochemical oxygen demand(BOD), ammonia nitrogen(NH3), total phosphorus(TP) and other indexes of landscape lake water were significantly improved after the remediation. The results of this study have guiding significance for water quality improvement, ecological construction and water management of urban landscape water.
