摘　　要：为研究大风对洪泽湖泗阳生态岛工程湖流影响,采用MIKE 3建立了洪泽湖三维水动力数学模型。通过实测资料对模型参数率定,验证结果良好,进而研究了不同工况条件下洪泽湖水动力特性及泗阳生态岛工程对其附近湖流动力影响特性。结果表明:洪泽湖湖区流场变化主要受大风影响,风向及水位的变化均能对湖区壅水及湖流结构产生影响。生态岛的填筑将导致湖区出现局部迎流侧流速增大、背流侧流速减小的现象,但对整个湖区湖流及环流结构基本无影响。研究成果可为洪泽湖泗阳生态岛工程安全运行提供技术支撑。To study the hydrodynamics of Siyang Ecological Island Project in Hongze Lake affected by strong wind,MIKE 3 was adopted to establish the 3D hydrodynamic mathematical model of Hongze Lake.The parameters was verified through the measured data with a sound result.The hydrodynamics characteristics under different running conditions of Hongze Lake and the influence of Siyang Ecological Island Project on hydrodynamics characteristics of the surrounding area were studied.The results showed that the flow field change in Hongze Lake was mainly affected by strong wind.The wind direction and water level changes can affect backwater and lake flow structure.The filling of the ecological island had little impact on flow and circulation structure.The local flow velocity was increased and the back flow velocity was decreased.The results can provide technical support for the safe operation of Siyang Ecological Island Project in Hongze Lake.
