摘　　要：河口地区海水环境变化复杂,岸滩侵蚀严重,入海径流对侵蚀的影响不可忽视。从入海径流量与河口盐度变化的关系入手,主要阐述了海水盐度变化对河口泥沙沉降及泥沙沉降后固结的影响,进而讨论盐度变化对河口沉积物侵蚀的影响,其中,着重对黄河口地区入海径流量与河口沉积物侵蚀的关系进行了探讨;并且概述了黄河口沉积物侵蚀相关的研究情况,指出在黄河三角洲等河口岸滩侵蚀的研究中,可以以盐度等为媒介,把入海径流与沉积物本身联系起来,综合考虑分析岸滩侵蚀机理。The marine environment in an estuary region varies complicatedly with severe coastal erosion,and river discharge is an unneglectable affecting factor.In order to reveal the relation between river discharge and estuarine erosion,in this article we studied the effect of river discharge on salinity change,the effect of salinity change on sediment deposition,consolidation and erosion,with emphasis on the effect of the Yellow River discharge on estuarine erosion.Related research status is reviewed.It is observed that salinity is a vehicle to connect the river discharge and sediments as far as coastal erosion is considered in an estuary area in the case of the Yellow River estuary.
