摘要:

为突破传统灌区管理瓶颈,推动灌区现代化转型与水资源集约节约高质量发展,围绕数字孪生技术在现代灌区管理中的应用展开系统研究,重点开展应用模式构建、实施路径探索及综合效益评估工作,并以全国首批数字孪生灌区试点山东省滨州市小开河灌区为案例开展实证研究。采用案例分析法、实证评估法,通过构建以“1+6+N”为核心架构的数字孪生平台,搭建“天空地水工”一体化智能监测网络,开发多模型协同模拟与仿真平台,建立基于数字孪生的智能调度与决策支持系统,实现对灌区水资源、工程设施、灌溉调度的全流程精准管控。应用实践表明:该平台显著提升灌区水资源管理效能,灌溉保证率提高约15%,灌溉水有效利用系数提升至0.65以上,年均节水约800万m³,成功实现灌区管理从经验管理到精准智能调控的转变。研究成果可为全国灌区现代化转型提供可复制、可推广的理论与实践参考。

Abstract:

To break through the bottlenecks of traditional irrigation district management and promote modernization transformation alongside high-quality, water-efficient development, this study systematically investigated the application of digital twin technology in modern irrigation district management. It focused on application model construction, implementation pathway exploration, and comprehensive benefit evaluation, taking the Xiaokaihe Irrigation District in Binzhou City, Shandong Province—one of the first national pilot digital twin irrigation districts—as a case study. Case analysis and empirical evaluation methods were employed. By constructing a digital twin platform with a core “1 + 6 + N” architecture, establishing an integrated intelligent monitoring network covering “Space-Air-Ground-Water-Engineering”, developing a multi-model collaborative simulation platform, and building an intelligent scheduling and decision support system based on digital twins, the study achieved precise, full-process management of irrigation district water resources, engineering infrastructure, and irrigation scheduling. The application results showed that the platform significantly improved water resource management efficiency in the irrigation district. The irrigation guaranteed rate increased by approximately 15%, the effective utilization coefficient of irrigation water rose to above 0.65, and annual water savings reached about 8 million m³, indicating a clear shift from experience-based management to precision-oriented intelligent regulation. The results offer replicable and scalable theoretical and practical references for irrigation district modernization.
