数字孪生灌区是智慧水利建设的重要组成部分，是提高水资源节约集约利用水平的关键手段，是提升灌区管理能力、提高粮食产能的重要举措，也是推进灌区现代化发展的重要路径。梳理了数字孪生灌区发展历程及取得的建设成效，分析了区别于灌区信息化建设的数字孪生灌区技术特征。在总结数字孪生灌区先行先试建设进展基础上，对当前数字孪生灌区建设中存在的问题等进行分析，指出当前数字孪生灌区建设还存在缺乏统筹规划、共享机制不完善、技术适配性不足、建管运维资金不足和技术力量薄弱等现实问题，并有针对性提出了构建标准体系、畅通数据共享渠道、聚焦关键技术研发、创新投融资模式和培育专业人才等对策建议，旨在为数字孪生灌区建设和高质量发展提供实践参考。

As an essential component of smart water conservancy, digital twin irrigation districts serve as a key means to promote the conservation and intensive utilization of water resources,enhance irrigation district management capabilities, and increase grain production capacity. They also represent an important pathway for advancing the modernization of irrigation districts. This study reviews the development process and construction achievements of digital twin irrigation districts,and analyzes their technical characteristics that distinguish them from traditional informatization efforts. Based on the progress of pilot implementations, current challenges are identified, including the lack of overall planning, incomplete data-sharing mechanisms, insufficient technical adaptability,inadequate funding for construction, management, operation, and maintenance, and limited technical capacity. In response, targeted recommendations are proposed: establishing a standard system,improving data-sharing channels, focusing on the research and development of key technologies,innovating investment and financing mechanisms, and cultivating professional talent. These suggestions aim to provide practical guidance for the construction and high-quality development of digital twin irrigation districts.
