Zusammenfassung:Disclosed in the present invention is a method for forecasting runoff under influence of an upstream reservoir group by utilizing forecasting errors. The method comprises: collecting data; establishing a regulation and storage influence quantity estimation model by utilizing a known hydrological model and a KNN model according to the collected data; driving the hydrological model by combining the collected data to predict a future runoff volume; obtaining a forecast error in a previous time period; obtaining a future regulation and storage influence quantity estimated value according to the forecast error in the previous time period in combination with the regulation and storage influence quantity estimation model; and superposing the future runoff volume and the future regulation and storage influence quantity estimated value to obtain a runoff forecast value in a future time period.
