Aiming at the problems of poor mobility of urban river network and increasingly serious water pollution in Xishan District,based on the observed data,a hydrodynamic water quality coupling model was constructed by MIKE11.Considering the joint operation of various water conservancy projects in the study area,NH3-N was used as the pollution factor,simulating a variety of water transfer schemes were simulated.The effect of water system regulation on the improvement of water flow and quality was analyzed.The results show that water transfer can improve the fluidity of the river and accelerate the replacement of water body;Scientific and reasonable water transfer scheme can greatly reduce the pollutant concentration of most monitoring sections in the study area,make the water quality reach class IV or even better,and effectively improve water environment in the study area.
