摘　　要：在上游河流治污截污工程完成、入湖水质达标的条件下,遵循“自然恢复为主、人工修复为辅”的保护修复原则,构建水位可调可控、湿地功能完善、生境健康稳定、生物多样性丰富、食物链构成完整的湖泊湿地系统。工程实施完成后湿地植物种类增加86种,植被覆盖率提高10.98%,鸟类数量增加28种,生境景观多样性指数从1.43提升至1.88。可有效提升出湖水质,降低巢湖和长江的污染物负荷,预计每年可削减COD 82.4 t、氨氮25.3 t、总磷3.2 t。改善区域自然环境,为区域生态价值转换、带动周边区域经济发展奠定良好生态基础,结合景观风貌营造丰富湿地生态景观,产生了较好的生态效益、环境效益和社会效益,为同类型湿地的生态保护修复提供借鉴和参考。Under the condition that the upstream river pollution control and sewage diversion project is completed and the inflow water quality meets the standard,the protection and restoration principle of“natural recovery as the main approach,artificial restoration as a supplement”should be followed to build a lake wetland system with water level adjustable and controllable,wetland function complete,ecosystem healthy and stable,biodiversity rich,food chain complete.After the project is implemented,the number of wetland plant species has increased by 86,the vegetation coverage rate has increased by 10.98%,the number of birds has increased by 28,and the landscape diversity index has been raised from 1.43 to 1.88.It can effectively improve the outflow water quality,reduce the pollutant load of Lake Chaohu and the Yangtze River,and is expected to reduce COD by 82.4 tons,ammonia nitrogen by 25.3 tons,and total phosphorus by 3.2 tons per year.It can improve the regional natural environment and lay a good ecological foundation for the conversion of ecological value and the promotion of economic development in the surrounding areas.By creating a rich wetland ecological landscape with scenic features,it has produced good ecological,environmental and social benefits,and provides reference and guidance for the ecological protection and restoration of similar wetlands.
