| Abstract: | 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. |
