摘　　要：近年来,因长江口上游径流、外海潮汐和河口海洋环境的剧烈变化以及长江口水域河口及海岸工程的大量兴建,特别是规模宏大的长江口深水航道治理工程的建设,可能会导致河口潮汐产生变化。对长江口深水航道工程建设前后长时间序列的11个潮位站潮位资料进行分析,得出长江口近期潮汐特性的变化特征:口外潮汐特性主要受外海潮汐总体变化影响,口内潮汐特性受北槽深水航道治理工程及周边涉水工程建设的影响。In recent years, because of the dramatic changes in the upstream runoff of the Yangtze estuary, seatide and estuarine marine environment, and more engineering constructions in the Yangtze River estuaries and alongthe coast, specially the constructions of the Yangtze estuary deepwater channel regulation project may cause somechanges in the tidal estuary. Based on the analysis of the Yangtze estuary deepwater channel project constructionbefore and after the long-time series of 11 tidal station data, we get to know the tide variation characteristics ofYangtze estuary in recent period and realize that the tidal characteristics out of the estuary is mainly affected by theouter tidal changes, and that in the mouth is mainly affected by the deepwater channel regulation project andsurrounding engineering construction.
