摘要
利用灰色系统理论的预测和决策功能,对粮食产量进行统计和预测。结果表明:用GM(1,1)模型对粮食产量预测,建模简单,预测精度高,在预测粮食产量、气候变化、农田灾害等方面有较大的实用意义。
Grain output was estimated by the forecast and decision-making functions of grey system theories to arrange agricultural production. GM (1,1) model with characteristics of high forecast accuracy and simple model set up method was used to forecast grain output, which had great practical significance in forecasting grain output, climate changes, farmland disasters and other aspects.
