摘　　要：根据平原河网的水动力和水质特点,建立了运河水系河网水质模型,并利用2007年该运河水系河网的实测水位及水质资料对模型进行验证。进行了杭州市主城区引配水方案下的水动力计算,并对设计水动力条件下的运河水质进行预测。结果表明,杭州市主城区引配水方案实施后,运河干流及主要支流水质将有较大改善。A river network water quality model of the Grand Canal river system was set up based on the hydrodynamic and water quality characteristics of a plain river network.The model was validated with measured water level and water quality data of the Grand Canal river system from 2007.The hydrodynamic condition in the main urban area of Hangzhou was computed according to the water diversion plan,and the water quality of the Grand Canal was predicted under the designed hydrodynamic conditions.The prediction results indicated that the water quality of the Grand Canal and the main tributary would be greatly improved after the water diversion plan was implemented.
