| Abstract: | A combined forecasting model was set up according to the least sum of the absolute value of forecasting deflection ,and grain yield of Qinghai province is forecasted and analyzed in this paper based on combined forecasting model whose weight is determined by linear programming. the result shows that the combined forecasting model has higher forecasting precision. |
| Keywords: | combined forecasting model linear programming grain yield |
