| 摘 要： | 科学准确地预测粮食产量，对于制定国民经济计划十分重要。目前粮食产量的预测方法很多，本文提出了粮食产量预测的灰色ＧＭ（１，１）模型群，并根据某县１９８１年～１９９０年的粮食产量资料，对该县１９９１年～１９９５年的粮食产量进行了预测。经分析，其预测结果可靠、预测精度比ＧＭ（１，１）模型大大提高。

| Abstract: | It is important to the national economic plan to forecast crop yields scientifically and accurately.This paper presents the Grey MODEL group for forecasting crop yields. It was used to forecast the crop yield of one county from 1991to 1995 based on the crop yields of the 1980's. The results indicated the MODEL'S precision was satisfactory. |
