摘要： 利用2005年春季水文泥沙测量资料和历史海图资料，在分析水动力条件、悬沙和沉积物特征基础上，对海床冲淤量进行计算，探讨了南汇嘴崎岖列岛海域海床演变的基本规律.得出最近50年来海区呈现淤积减弱和冲刷加强的趋势，而造成这一趋势的原因主要包括海洋动力作用、长江入海泥沙变化以及近岸大型海岸和海洋工程的建设等.

Abstract: Based on the hydrological and sediment survey datum in the spring of 2005 and the history sea charts, from the points of view on hydrodynamic condition, suspended sediment, sedimentary character, scouring and silting of the seabed, the evolution law of the seabed in the sea area of Nanhuizui and Qiqu Archipelago was analyzed. A trend of weaker silting and stronger scouring of this sea area in the recent 50 years was found, which is caused by the effect of ocean dynamics, the change of sediment flux to the sea and the constructions of some great coastal engineering projects.
