摘　　要：通过分析水文泥沙资料和多年海图资料,研究1931—2004年间椒江河口湾海床演变及其原因。结果表明:1931—1970年,椒江河口湾岸线向海推移、推移速率较快,湾内普遍发生淤积;之后,由于来沙减少、口外两侧滩面减小和海堤的束水作用等原因,河口深槽及口外航道冲刷,其余区域淤积变轻、并趋于床面基本稳定。The seabed process of the Jiaojiangkou bay from 1931 to 2004 and its mechanism are studied by analyzing the hydrology, sediment and topography data. The results show that from 1931 to 1970, the shorelines of the Jiaojiangkou bay were advanced rapidly towards the sea, and siltation occurred widely in the Jiaojiangkou bay; After 1970, erosion was presented in the channel of the bay top, while siltation in the rest of the Jiaojiangkou bay became slight and the rest tended stabile, which mainly resulted from the reduction of incoming sediment, decrease of the shoals on both banks and effect of seawall＇s converging.
