Urban river restoration is an important work for improving urban ecological environment. In order to build a healthy aquatic environ-ment, it is ncessary to study the feasible technical scheme to improve waler quality. One -dimensional hydrodynamic and water quality modelwas constructed based on the MIKE11 software platform. According to the pollution features of Shiwuli basin, three scenarios using dfferentmeasures were planned to analysis and evaluate the efet on water quality improvement. The results indicate that olluant discharges alone bereduced cannot make the water quality of the cross section meet Class v, but it would cause river channel drought out. Instead, the water qualityimprovement in the basin can be achieved by reducing pollutan discharges and enhancing the efluents quality of wastewater treatment plants.However, at some times, water quality cannot meet the standard because of rainfall runoff carrying pollutants into river. The cross section waterquality can meet the standard through cutig off initial ninfal runof, reuaing relimedd water, and upplyring water wih proximity principlewithout an extermal water supply.
