| 摘 要： | 采用了一种基于时间序列数据的灰色—线性回归模型对广西某市的粮食作物播种面积的单产进行了预测，并将预测结果及预测误差与线性回归模型及灰色GM（1，1）模型的预测结果进行了比较。结果表明，灰色—线性回归组合模型进行粮食作物耕地需求量预测精度较高，具有科学可行性。

| Abstract: | The crops yield of per unit area in a City of Guangxi Province was predicted by a combination model of grey-linear regression based on time series data.The predicting results forecasting error of linear regression,grey GM(1,1)and combination model of grey-linear regression were compared.The research results showed that the predicting result of crops yield of per unit area by gray-linear regression model has high precision and scientific feasibility. |
