摘要
本文应用灰色系统理论的原理和方法建立了河北省干、鲜果品产量的灰色动态预测模型,模型精度分别达到99.37％和99.56％.对该省未来年份干、鲜果的生产趋势进行了预测.
The principle and method of Grey System Theory has been adopted to establish Grey calculating model for the yield forecast of fresh and dry fruit in Hebei Province. Their precision reaches 99.37% and 99.56% respectively.And the future trend of fresh and dry fruit yield in the province has been predicted by means of the 2 models.
