摘要
为探索长江生态航道的建设,依托长江南京以下12.5 m深水航道建设工程,针对工程河段生态环境特点及保护需求,研发多种生态型整治建筑物结构。在工程受影响区域,探索人工鱼巢、生态浮床等生态修复尝试。计算与分析潮汐河段施工引起的水体悬浮物浓度对取水口及水源地影响,提出防护方案。在研究噪声对江豚影响的基础上,提出声学驱赶与声学诱导技术。提出全过程的生态环境保护措施与管理办法。成果均已应用于长江南京以下深水航道工程,结果表明生态效果良好,无生态环境事故发生。
Based on the 12.5 m water depth navigation channel regulation project and the ecological features and environmental protection requirements in this river section, we explore techniques on ecological channel construction. A wide variety of ecological structures of waterway regulation was developed, and restoration engineering of artificial fish nest and ecological floating islands were also built to provide habitats for the aquatic organism.The impact of the suspended matters induced by the construction on water source sites in the tidal river was simulated and analyzed,and proper scenarios were proposed accordingly.The techniques of drive and induction of the Yangtze finless porpoise were studied based on the influence of noise,also the ecological and environmental protection measures for the overall process of construction were put forward together with the management methods.All the research results have been applied to the navigation channel regulation project in the Yangtze River below Nanjing and distinguish ecological effects have been achieved,and no environmental accidents happened.
