| 摘 要： | 由于南方地区冬小麦白粉病的预测是一项多因素的复杂工程,因而针对传统预测方法的不足,提出了一种基于灰色系统GM(1,1)理论和BP神经网络相结合的预测模型。灰色系统GM(1,1)模型理论建模方法简单,计算量小,而BP算法特别适合于对GM(1,1)模型进行残差修正,利用两者的结合可以建立较高精度的预测模型。利用该模型对南方某地区冬小麦白粉病进行了预测,结果表明,该模型准确有效,适用于该地区的冬小麦白粉病的预测。 |

| Abstract: | The prediction of winter wheat powdery mildew in the south area is a multi-factor complex projects,as the deficiencies of traditional forecasting methods,a new prediction model which combined the grey system GM(1,1) theory with the BP neural network is proposed;because grey GM(1,1) model theory is simple and computation,and BP algorithm is especially suitable for GM(1,1) model residual modification,it can be established using a combination of high precision prediction model;the winter wheat powdery mildew o... |
