Abstract: According to the dispatching scheme in the project proposal of Poyang Lake Water Control Project,we constructed a two-dimensional hydrodynamic model and quantitatively analyzed the influence of Poyang Lake Water Control Project on dispatching water resources utilization in the lake area under 20 working conditions.The results showed that:in the early stage,the influence of project's dispatching on water resources utilization was the largest;while,the influence decreased from north to south with the decrease of water level after dispatching.In addition,the water level outside the water intake can basically meet the requirements of water diversion in drought and extremely drought years through dispatching.The results can provide reference for comprehensive management of Poyang Lake.
