摘　　要：以淮河流域中下游结合部的洪泽湖周边滞洪区为研究对象,基于紧耦合技术,将一维和二维水动力模型进行耦合,基于松耦合技术,将气候模型与水文模型、水文模型与水动力模型进行耦合,实现了流域、河网、蓄滞洪区和湖泊复杂系统气候水文水动力单向耦合,并对气候变化影响下的复杂河网地区水流演进进行了模拟。结果表明:构建的气候-水文-水动力耦合模型对洪泽湖周边滞洪区洪水演进具有较好的模拟能力和适应性;气候变化导致未来淮河流域洪水量级增加,加大了洪泽湖周边滞洪区的洪水风险。Taking the flood detention area around Hongze Lake at the junction of the middle and lower reaches of the Huaihe River Basin as the research object,the one-dimensional and two-dimensional hydrodynamic models are coupled based on the tight coupling technology.Based on the loose coupling technology,climate model is coupled with hydrological model and hydrodynamic model.The climate-hydrologic-hydrodynamic one-way coupling of the complex system of the basin,river network,flood storage and detention area and lake is realized,and the water flow evolution in the complex river network area under the influence of climate change is simulated.The results show that the constructed climate-hydrologic-hydrodynamic coupling model has good simulation ability and adaptability for flood routing in the flood detention area around Hongze Lake.Climate change will increase the magnitude of future floods in the Huaihe River Basin,and increase the flood risk in the flood detention area around Hongze Lake.
