The chaos theory is used to test chaotic characteristics of the disaster rate of wheat rust certain part of Hubei province.Then the forecasting model is established to forecast the disaster rate by combining BP-NN with GA.With reconstruction of phase space,determining the input numbers and values and the optimized BP algorithms,the disaster rate has been successfully forecasted.
