| 摘 要： | 本文由作物产量序列提取出显著周期分量,建立带有周期分量的逐步回归预报模型;运用时间序列的方差分析方法,建立作物产量的预报模型。从对所得模型的统计检验和几年的试报效果来看,这两种方法都具有一定的预报精度。

| Abstract: | The model of crop yields prediction with periodic component was built by using the method of stepwise regression and the model of crop yield prediction was built by using the method of variance analysis in time serise. The statstics test and prediction result showed that both the methods have certain prediction precision. |
