【Abstract】 This paper analyzed many methods’ application scope, the application condition and the existence questions such as the elastic method of correlates, the exponential method, the grey forecast model. Through Comparing mutually, this paper applied the grey forecast model to quantity of city sewage. It took Hefei city as an example. The forecast result indicated this model has high precision, and this method is feasible.更多还原
