基于ARIMA时序模型的灌区供需水量预测研究OA
Research on water supply and demand forecasting in irrigation areas based on the ARIMA time series mode
为实现茨淮新河灌区水量分配与管理的科学预测,基于1991-2023年灌区抽水量实采数据建立灌区水量供需平衡分析体系.利用灰色关联度分析和ARIMA时序模型分析农业、生活、航运等场景的需水量指标对总抽水量的影响,并预测灌区未来水量需求.结果表明,灌溉需水与实际抽水量的关联度最高达到 0.8983,通过多重检验和模型训练,ARIMA模型的预测准确率达到了88.587%,可以为灌区水量供需与调度提供有效参考.该预测方法可推广至其他水资源紧张区域,为水量…查看全部>>
To achieve scientific prediction for water allocation and management in the Cihuai New River Irrigation Area,an ana-lytical system for the balance of water supply and demand was established in the irrigation area,using the actual water extrac-tion data from 1991 to 2023.Using grey relational analysis and the ARIMA time series model,the impact of water demand indi-cators such as agriculture,domestic use,and navigation on total water extraction and forec…查看全部>>
