Abstract：Based on the existing data and resources of the Ministry of Water Resources,the studies focuses on precipitation forecast by integrating subjective and objective factors in a refined manner and develop a set of technical methods.Selecting four big floods during 2022 to 2023,the results of forecasts by subjective-objective integration,subjective forecasting,and objective forecasting of the European Centre for Medium Range Weather Forecasts(ECMWF)in nine river basins were tested against the actual situation.The results indicated that the subjective-objective integration method had better performance in spatial integration and temporal decomposition than subjective or objective forecasting.
