| 摘 要： | 以云南楚雄1999-2005年耕地面积数据为试验资料,运用灰色GM(1,1)模型分析探讨耕地面积的变化状况.初步结果表明:楚雄耕地面积的动态变化结果符合客观实际的变化规律,未来几年,楚雄拼地面积仍呈递减的趋势. |
| 关 键 词： | 灰色GM(1 1)模型 耕地面积 预测方法 精度 |

| Abstract: | With the cultivated land data of Chuxiong city in Yunnan provice during 1999-2005 as experimental data,based on gray model GM(1,1) analyzed changes in status of the cultivated land.The preliminary result indicated:with Gray GM(1,1) model to predict Chuxiong the dynamic results are in accord with objective reality,in the next few years,Chuxiong cultivated land continued to show a decreasing trend. |
| Keywords: | Gray Model GM(1 1) cultivated land prediction accuracy |
