摘　　要：随着人类活动加剧及气候变化影响,五河(赣江、抚河、信江、饶河、修河)来水及长江干流来水条件发生较大改变,江湖河水文关系发生了变化。通过构建长江—鄱阳湖—五河尾闾一维、二维耦合水动力学模型,模拟研究五河来水、长江来水及区间降雨极端组合情景下鄱阳湖出湖流量,分析在不同情景下鄱阳湖出流规律。研究结果为鄱阳湖防汛抗旱、水资源管理决策提供技术支撑与方法参考。With the intensification of human activities and the impact of climate change,the conditions of the in⁃flow of the five contributing rivers(Ganjiang River,Fuhe River,Xinjiang River,Raohe River and Xiuhe River)and the main stream of the Yangtze River have changed greatly,and the hydrological relations among rivers and lakes have also changed.This paper constructed one-dimensional and two-dimensional coupled hydrodynamic model of the Yangtze River-Poyang Lake-Five River tails,simulated the outflow of Poyang Lake under extreme combined scenarios of the five rivers inflow,the Yangtze River inflow and interval rainfall.The results could pro⁃vide technical support and method reference for flood control,drought relief and water resource management deci⁃sion-making of the Poyang Lake.
