利用历史资料和不同年份海涂地形图 ,揭示近 1 0年来上海滨岸潮滩不同岸段的冲淤变化 ,重点分析南汇东滩和杭州湾北岸的冲淤变化特征。研究表明 ,整个南汇东滩近1 0年来均呈淤涨态势 ,而杭州湾北岸冲淤变化则比较复杂 ,岸段冲刷和淤积交替出现。不同岸段潮滩冲淤变化 ,揭示出滨岸潮滩发育不仅受自然因素控制 ,也受人类活动的深刻影响。 Based on the historical data and the topographic maps of the tidal flat in different years, the change of the scouring and silting in different shore sections of Shanghai coastal tidal flats in recent 10 years is revealed. The variation characteristics of the scouring and silting in the east bank of Nanhui and the north bank of Hangzhou Bay are analyzed. The research shows that the whole East Bank of Nanhui has a tendency of silting up in recent 10 years, while the erosion and siltation in the north bank of Hangzhou Bay is rather complicated, and the scouring and silting in the shore section alternate. Erosion and deposition of tidal flats in different banks have revealed that the development of coastal tidal flats is not only controlled by natural factors but also profoundly influenced by human activities.
