%X It is of great importance to predict the spreading peak of schistosomiasis. This paper establishes a difference gray prediction model, which forecasts the peak peroid of schistosomiasis growing and spreading. A practical example is caculated and analyzed, which indicates that the prediction result is correct and the precision grade of the model is excellent.
