Application Grey System to Forecasting Irrigation Area and Irrigation Water Consumption

摘要：

Based on the theory of grey system, this paper established GM (1,1) model to forecast irrigation area and water consumption in Hebei province. Checked up the model with residual error text, relational coefficient test, variance test, and little probability of error test, the precision of the model is good enough to meet the requirement , proved the feasibility and adaptable of the method. So it can be used to forecast irrigation area and water consumption. The result of this model will be the key to upgrade irrigation agriculture in this area in the future.
