摘要:长江口是我国最大的河口,建设在长江上诸多水利和海岸工程对于长江口的生态环境叠加着复杂的影响。如在干流和支流上已建和在建的许多大大小小的水利工程,特别是如三峡大坝建设、南水北调工程、引江济太工程、长江口深水航道工程,将显著改变长江的水、沙动态,改变营养物质的输移特征,不仅直接影响下游河道的水文、水环境条件,而且对远离工程的河口生态环境也将产生显著和潜在的影响。水利工程对于长江口生态的影响表现在水质、盐水入侵、海岸侵蚀、生物多样性方面。

Abstract:Yangtze River Estuary is the largest estuary , water conservancy construction in the Yangtze River and Coastal Engineering affects many ecological environment of the Yangtze River port complexly . Many large and small water conservancy project on the River and tributaries such as stabling , especially as the Three Gorges Dam construction , water diversion project , Taihu project , the Yangtze River Estuary project will significantly change the water of the Yangtze River Sediment and the transport characteristics of nutrients, not only it directly affects the downstream river hydrology , water environmental conditions , and to stay away from the project estuarine ecological environment will also have a significant and potential impact. Water conservancy and ecological effects of the Yangtze Delta performance in quality , saltwater intrusion , coastal erosion, biodiversity . Hydraulic engineering makes effects in water quality and saltwater intrusion and coastal erosion and biodiversity.
Key words: hydraulic engineering; Yangtze River Estuary; coastal erosion;
自十九世纪以来 ,世界上许多河口都受到人类活动的显著影响。一些资本主义发展较早的国家陆续在主要河口进行了治理工程 ,尤其是二十世纪七十年代以后 ,
