摘要
本文应用灰色系统理论,建立了福建省光泽县粮食总产量的动态模式,分析了该县粮食产量的历史变动状况,并对1991~2000年的粮食产量进行预测.模型采用两种特殊措施,极大地提高了预测精度。
By using the grey system theory,this paper has set up a dynamic model of the total grain yields in Guangze County,Fujian Province,analyed the yield change in history and made a forecast in grain yield of 1991~2000.Two special dictions have been used in the model so that the forecasting precision is greatly raised.
