基于改进B-P算法的内蒙古粮食产量中长期预测

Middle and long term forecasting the grain gross output of Inner Mongolia with back-propagation algorithm

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 2 0 0 2～ 2 0 1 1年 ,内蒙古粮食总产量由 2 0 0 2年的 1 4 75 .5 7万 t增加到 2 0 1 1年的 2 1 0 3.4 3万 t,呈现出稳定增加的趋势。

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.
