摘　　要：盘锦双台子河口湿地拥有亚洲面积最大的芦苇种植区,但随着工农业用水增多,加之气候干旱和降雨偏少,苇田灌溉得不到保证。为了更好地解决双台子河流域苇田灌溉用水不足的问题,本文利用实测水位和流量等资料,基于Mike11建立了双台子河口的水动力学模型,并使用2008和2009年的实测潮位资料对模型进行了率定和验证,拟合精度较高,表明所建模型能反映河口区的水动力特征。通过设置水工建筑物的不同运行方式,模拟了上溯潮水分流到支流绕阳河与双台子河上游的流量比值。结果表明,水闸和橡胶坝对于研究区域内上溯潮水的分流比影响较大,在现状基础上橡胶坝建成之后能将绕阳河的分流比提高约50%,同时下游河口上溯潮水会减少20%～30%,但分流比对橡胶坝高度的变化并不敏感。不同调水方案以及水泵提水对分流影响甚微。Shuangtaizi estuary wetland in Panjin is the largest reed growing areas in Asia. Under the growing us age for industrial and agricutlcral water, combinecl with the effects from aridclimate and low rainfall, irrigalim of reed fields can＇t be guaranted. In order to solve the water shortage of reed field irriga-tion in Shuangtaizi estuary, this paper builds a hydrodynamic model based on Mike11 by using the latest water levels, discharge and river cross-section data. Then the model is calibrated and validated by the measured tidal data of 2008 and 2009. Under the different control modes of hydraulic structures, this pa- per analyzes the flow ratio of upstream and tributaries. Results show that the sluice and dam have obvious effect on the flow ratio. Flow ratio of Raoyang river can increase about 50% after the completion of rub-ber dam. At the same time, amounts of upstream tidal water will reduce by 20%-30%. The flow ratio is not sensitive to changes of rubber dam height. Different irrigation plans and operation modes of pumping station also have little effect on flow ratios.
