The Huaihe River running through the eastern part of China is the main water source of the five provinces of Hubei,Henan,Anhui,Shandong and Jiangsu,and has great effect on the economic development of these regions.In this study,the Huaihe River is divided into five reaches according to the actual conditions of the river basin.The shadow price of water resources,that is theoretical water resources value for different water use departments in each channel reach is obtained by means of developing and seeking solutions of the model for optimizing allocation of the basin's water resources,which can provide scientific basis for the formulation of the level of water resources value of Huaihe River.
