摘要
本文运用灰色系统理论建立了常德市油料作物产量的预测模型,其模型的精度达到了一级水平,模型值的精度在95％以上。模型的预测值评估结果良好,说明油料作物产量的预测值是可信的。
In this paper using theory of gray system was established the oil-crop yield prediction model in Changde city, Hunan.The results showed that the precision of model is very high and the precision of model values reaches above 95%.The evaluation for model prediction values was satisfactory too. It is believable, that grey dynamic model was used to predicting oil-crops yield.
