| 摘要: |
| 在改进B-P算法、提高B-P算法预测精度的基础上，对内蒙古粮食总产量进行了预测。结果表明，在2002～2011年，内蒙古粮食总产量由2002年的1 475.57万t增加到2011年的2 103.43万t，呈现出稳定增加的趋势。最后提出了实现内蒙古粮食预期产量应采取的措施。 |

| Abstract: |
| This paper forecasted the grain gross output of Inner Mongolia by improved back propagation algorithm with high forecast precision.The forecasting result showed that the grain gross output of Inner Mongolia has a stable increasing trend from 14.755 7 million tons in 2002 to 21.034 3 million tons in 2011.Finally,this paper put forward the methods to achieve the forecasting of outputs. |
