The crops planting scale in the irrigation district is usually determined according to the agriculture general programming,the crops planting and cultivation custom.In irrigation district programming,different crops planting scale has decisive effects on the scale of the water resources and water-supply project.Based on accurate long-term weather forecasts,the deterministic and random models for the crops planting scale optimization are established under the definite condition of the multiple cropping indexes and the circumstance of upcoming meteorological disasters year.The results of example calculation show that using the two models to optimize the crops planting scale in irrigation district has practical significance for overcoming the risk of production reduction.
