应用GM(1,1)模型预测沧州冬枣的种植面积及产量

Application of GM(1,1) Model in Forecasting the Planting Area and Yield of the Winter Chinese Date in Cangzhou

采用灰色理论中的GM (1,1)模型,用MATLAB语言编程,以沧州2 0 0 0～2 0 0 4年冬枣种植业的有关原始数据,对该地区冬枣种植面积和产量进行了实例分析、检验。进而用该模型预测出2 0 0 5年沧州冬枣的种植面积和产量,为有关部门正确决策提供了科学依据。

The planting acreage and yield of winter Chinese date in Cangzhou region were analysed in instances by using the model of GM(1,1) by MATLAB language according to the original data of the winter date in Cangzhou from 2000-2004. The planting acreage and yield in 2005 are forecasted by this model with provides scientific advice to correlative departments for proper decision-making.
