| Abstract: | Grain output was estimated by the forecast and decision-making functions of grey system theories to arrange agricultural production.GM(1,1) model with characteristics of high forecast accuracy and simple model set up method was used to forecast grain output,which had great practical significance in forecasting grain output,climate changes,farmland disasters and other aspects. |
