考虑到灌溉供水过程和作物需水过程的不确定性和不确知性，建议了一种以灰色系统理论为基础的灌区作物种植方式决策模型。利用该模型可为灌区选择适当的种植方式来适应不同年度供水量的变化，以达到农业稳定发展的目的。模型中涉及到的参数，可根据农业生产实践和专家经验很容易给出，在计算方法上也较筒单。文章最后以示例说明了该模型的具体应用。
Considering the uncertainties and uncertainties in the process of irrigation and water supply and the process of crop water demand, a decision-making model of cropping system based on gray system theory is proposed. The model can be used to select suitable planting methods for irrigation district to adapt to the changes of water supply in different years so as to achieve the stable development of agriculture. The parameters involved in the model can be easily given on the basis of agricultural production practices and expert experience, and are relatively simple in terms of calculation method. Finally, the article illustrates the specific application of the model.
