Hydrological forecasting is of great significance to the successful water resources management and scheduling,social production and life.According to the limitation of the past chaos forecasting methods,the combined method of runoff time series forecast was developed,based on ANFIS and chaos theory.The runoff time series were decomposed as trend component,periodical component and random component,and the existence of chaos was determined in the random component.Then the model of ANFIS was built to forecast the random component.Finally,all the components were superposed in a linear way to forecast the runoff.Examples showed that the method had good prediction accuracy and generalization ability.
