摘要
以灰色理论为基础,介绍了灰色波形预测的原理和步骤,并结合实际,建立了商城县年降雨量波形预测模型,对所建模型进行误差检验,结果表明该预测模型具有较好的可行性和较高的精度。在此基础上对未来降雨量进行预测,这对该地区水库的优化调度和农业生产有重要的指导意义。
Based on the grey theory, the principle and processes of grey undee forecast were introduced. Combined with the fact of Shangcheng County, the annual rainfall undee forecast model was built. The results showed that the model was feasible with higher accuracy. On this basis, the rainfall in the future was predicted, which was very guidable to the optimization operation of the reservoir and agricultural production in this region.
