城市景观水体水质净化和生态修复研究

Water Purification and Ecological Remediation for Urban Landscape Water

通过分析上海曲阳公园中心湖水体的污染原因、污染状况和湖体水质分析,确定中心湖生态修复技术。通过对中心湖的水生植物系统、水生动物系统及微生态系统的修复,使水体具备自我净化的能力,并维持水中生态系统的平衡。结果表明,水生态系统建成1 a后,中心湖水体透明度、化学需氧量(COD)、氨氮(NH_3-N)、总磷(TP)等均较构建前有显著改善。此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。

by analyzing the causes of pollution,pollution status and water quality of Central Lake in Shanghai Quyang Park,the ecological remediation techniques for Central Lake were determined.In order to maintain the balance of aquatic ecosystems,the purification abilities to improve the water environment were studied,by rehabilitating aquatic plant system,aquatic animal system and micro-ecosystem.The results of the transparency,chemical oxygen demand(COD),ammonia nitrogen(NH3-N),total phosphorus(TP),etc.of Central Lake were better than before,after aquatic ecosystems had been completed 1year.The research results have guiding significance to the improvement of water quality,ecological construction and later stage management of urban landscape water.
