摘　　要：从单点灰色模型入手,通过扩展,导出多变量灰色模型,根据已知过去几年数据建立灰色模型进行拟合和预测,为科学种田提供了依据.Based on single-point gray model, the deformation prediction model is extended to a multivariable gray model. The fitting and predicting of the proposed multi-variable gray model are given by using the data of past several years. The model can used to forecast the per unit yield of crops, and provides the basis for scientific farming.
