摘　　要：选取低含沙水沙系列、枯水多沙水沙系列以及规划设计的未来50 a水沙系列,利用黄河下游一维水沙数学模型,模拟计算了对口丁坝双岸治理方案下黄河下游河道在3种水沙系列条件下的冲淤状况。结果表明,游荡性河段采用对口丁坝方案整治后,输沙能力得到了提高,该河段多输送的泥沙一半以上输送到利津以下,其余部分淤积在高村—利津河段,其中淤积以高村—艾山河段为主,艾山—利津河段的冲淤情况与现状相比变化不大。The governance strategies and regulation measures for the Yellow River have always been discussed for generations. In recent years,some researchers suggested controlling the wandering reach with the counterpart spur dikes in the Lower Yellow River to increase the sediment transport capacity. To study the effects of the counterpart spur dikes,three different kinds of runoff and sediment series were selected. The erosion and deposition situation in the Lower Yellow River was simulated by a 1-D numerical model. The results indicate that the sediment transport capacity of the wandering reach can be increased under the remediation of counterpart spur dikes. More than a half of the extra sediment from the wandering reach is transported to the downstream reach of Lijin station. The rest deposits between Gaocun and Lijin station,especially in the reach from Gaocun to Aishan station. The erosion and deposition situation between Aishan and Lijin station varies little before and after the construction of counterpart spur dikes.
