摘　　要：基于Mike11 HD和AD模块建立双台子河口区感潮河段水动力-水质耦合模型,利用实测资料对水动力、水质模型参数进行了率定和验证。利用所建模型,以夏灌期为例分析了在两种水文条件下橡胶坝对支流绕阳河纳潮的影响。结果表明,在两种水文情景下,建橡胶坝后纳潮量分别增加18.3%和16.9%,最大流量分别增加了32.7%和31.2%。盐度分析表明修建橡胶坝对绕阳河纳潮盐度变化影响不大,可满足苇田灌溉对盐度的要求。研究结果可为盘锦双台子河口苇田科学灌溉、促进增产提供技术支持。The hydrodynamic and water quality model for the tidal river in the Shuangtaizi River Estuary based on Mike11 HD-AD modulesis was built.The river channel roughness and longitudinal dispersion coefficient were calibrated and validated using the measured data.Then,the effects of rubber dam in the downstream of Shuangtaizi River on the tidal prism of Raoyang River were studied.The results showed that the construction of rubber dam could increase the tidal prism significantly.Under the two hydrological scenarios,the tidal prisms of tributary were increased by 18.3% and 16.9%,respectively.The maximum tidal quantity in the Wanjintan gate was increased by 32.7% and 31.2%,respectively.The construction of rubber dam has little effect on the salinity of tidal prism which is below the salinity limitation（〈5） for the irrigation.Therefore,the water in Raoyang River could be used to irrigate the reed field in summer.This study provided the technical supports for the reasonable irrigation and yield increase of reed field.
