We divide the national water into industrial , agricultural and domestic water according to some information of china's ministry.We obtain polynomial regression models and forecast the demand for water in industrial and agricultural from 2013 to 2015 year.Using a Grey model, we forecast the demand for domestic water from 2013 to 2015 year.Moreover, we conclude that the demand for water is 6273.997~6789.148 billion cubic meters in the future.Our conclusions are better than <the comprehensive report of China's sustainable development strategy research >.
