灰色系统理论在土地规划中的应用

The application of the theory of grey system in land planning

农业经济系统是一个灰色系统。本文以河北省武安市农业总产值的预测为例 ,首先通过灰色关联分析确定其优势产业 ,然后 ,通过时间序列建立灰色预测模型 (GM(1,1)模型 ) ,并对农业总产值进行预测与分析 。

This paper describes an approach to the application of grey predication model in land planning. As a case, a predication of agricultural total output value in Wuan city(Hebei province) is introduced. At first, the dominant industry is confirmed by grey correlation analysis, then a grey predication model (GM(1,1)) is constituted. In the end, agricultural total output value is predicated and analyzed.
