摘要

摘要: 嘉兴南湖是中国共产党诞生之地、革命红船的启航之地,南湖“秀水”至关重要。2018年南湖水体透明度不足30 cm,感官较差,水体氮、磷营养盐浓度居高不下,不能满足水环境功能区水质目标要求(GB 3838—2002《地表水环境质量标准》Ⅲ类水质)。通过对南湖水系特点和水环境现状进行深入分析,以南湖水质整体提升为目标,以降低水体中悬浮物浓度、提高水体透明度为核心,坚持污染治理与生态修复相结合,从源头管控、入湖清水廊道构建、河口水质强化净化、湖体生境改善和长效管护5个方面提出保护与修复措施,以期使南湖水生态系统恢复至良性循环状态,并最终实现南湖“秀水泱泱”。

Abstract: Nanhu Lake in Jiaxing City is the birthplace of the Communist Party of China and the place where revolutionary red ships set sail, and the “beautiful water” of Nanhu Lake is very important. In 2018, the water transparency of Nanhu Lake was less than 30 cm, with poor senses and high levels of nitrogen and phosphorus in the water, which cannot meet the water environment functional areas goals and objectives, i.e. Grade Ⅲ of Environmental Quality Standards for Surface Water(GB 3838-2002). The characteristics and environmental status of Nanhu Lake water system were analyzed and the overall improvement of water quality of Nanhu Lake was taken as the goal, focusing on the reduction of suspended solids content and improvement of water transparency, and insist on the principle of the combination of pollution control and ecological restoration, the protection and restoration measures were proposed. These measures included five aspects, including source control, construction of clear water into the lake corridor, enhanced purification of the estuary, improvement of biological environment and long-term management, in order to restore the water ecosystem of Nanhu Lake to a virtuous cycle, and finally achieve the beautiful water environment of Nanhu Lake.
