摘　　要：利用黄河口实测水文及潮汐资料分析计算了海向来沙情况。结果表明:海向来沙量与陆向来水来沙条件有关,两者表现出此强彼弱的特性,并且当陆向来水来沙较小时,海向来沙量较大;海向来沙量的大小除了与陆向来水来沙条件有关外,还与口门的边界条件等有关。同时指出,如果未来陆向来水来沙量持续偏枯或特枯,那么海向来沙量的变化及其对河口治理的影响还有待详细观测和进一步研究。The paper analyzes and calculates the sediment coming from the sea by utilizing the observed hydrological and tidal data of the Yellow River estuary.The outcomes show that the amount of sediment coming from the sea is related to the coming water and sediment conditions from land.When the amount of coming water and sediment from land is smaller,the amount of sediment coming from the sea will be greater.Besides the conditions of coming water and sediment from land,the amount of sediment coming from the sea is also related to the boundary condition of the outlet.It points out that it needs further observation and study on the variations of sediment coming from the sea and its influence to the management of estuary if the coming water and sediment from land keeping less or extremely little continuously in the future.
