以深圳麒麟山天鹅湖为例的南方城市湖塘整治

Taking Swan Lake of Qilin Mountain in Shenzhen as an Example for Improvement of Lakes and Ponds in Southern Cities

以深圳市麒麟山天鹅湖水系整治为例,介绍了整治相关工程及强化管控措施。工程措施主要包括双水源保障、水动力条件改善、生态湿地构建、水生植物改造以及水生态系统修复等。管理措施主要包括季节性差异运行以及水生态系统常态化运行方法。整治后天鹅湖水质和感官改善明显,其中叶绿素a的含量下降90%以上,透明度由最小20 cm左右提升至100 cm以上,可为后续类似工程提供借鉴。

Taking the improvement of the Swan Lake water system in Qilin Mountain,Shenzhen as an example,the engineering measures as well as the management and control measures are introduced.The engineering measures mainly include double water sources supplementation,hydrodynamic condition improvements,ecological wetlands construction,aquatic plants transformation,and aquatic ecosystem restoration.The management measures mainly include seasonal differential operation and normal operation of water ecosystem.After remediation,the water quality and sensory condition of Swan Lake have been significantly improved.The content of chlorophyll a has dropped by over 90%,and the transparency has increased from a minimum of about 20 cm to over 100 cm,which could provide a reference for subsequent related similar projects.
