摘　　要：针对妫水河流域存在的底泥淤积、生态基流不足、植被生境单一、水质功能不达标等实际问题,采用生态清淤/底泥堆岛原位降解、外调水源/再生水补给、浅滩深潭/水生植物修复、水量循环/旁路湿地净化、流域水土保持与面源污染生态修复等多项生态修复技术进行综合治理,实施后项目区生态流量较实施前提高10%以上,水生植物多样性指数由0.3提升至1.8,有效保障了谷家营考核断面COD_(Mn)、TP、氨氮三项常规指标满足《水污染防治行动计划》相关考核要求,同时对TN具有一定的去除效果;通过营造浅水湾和生境岛,辅以植物色彩配比和植物色彩季节变化,营造了良好的生态景观效果。This study presents an ecological restoration project in the Guishui River basin,which addresses issues such as sediment deposition,insufficient ecological base flow,limited vegetation habitat,and substandard water quality.The project employs a suite of ecological restoration technologies,including ecological desilting and in‑situ degradation of sediment islands,external water diversion and reclaimed water supply,shoals,deep pools and aquatic plant restoration,water circulation and bypass wetland purification,as well as soil and water conservation and ecological restoration of non‑point source pollution in the watershed.These measures have increased the ecological flow in the project area by over 10%and raised the aquatic plant diversity index from 0.3 to 1.8.Additionally,the project ensures that the three key water quality indicators(COD_(Mn),TP,and ammonia nitrogen)meet the requirements of the Action Plan for Prevention and Control of Water Pollution policy at the Gujiaying monitoring section.The project also demonstrates some removal of TN and creates an improved ecological landscape by constructing repulse bays and habitat islands,with optimized plant color ratios and seasonal variations.
