Apple output forecast can not only provide reliable basis for social and economic management decisions,also provide important data for budget plans of the relevant departments.The exponential curve model,multiple linear regression model and combination forecasting model were introduce at first.By comparison,combination forecasting model can take full advantage of single forecast method,and effectively reduce the influence of random factors of single forecast model.thus forecast accuracy and stability can be improved.The combination forecasting model is also suitable for apple output,which is appropriate combination between exponential model and multiple linear regression model,and the optimal solution of unknown parameters in mathematical expressions in the model can found by using genetic algorithm.Experiment results showed that the forecast results of combination model were superior to that of single model.
