灌区工程数智化升级的实践分析与发展路径思考OA

Digital twin irrigation districts are an important component of digital twin water conservancy projects and a core practical form of the digital and intelligent upgrading of irrigation district engineering,playing an important role in promoting the high-quality development of irrigation districts in the new stage.Based on the tracking and evaluation results of 49 pilot digital twin irrigation districts,this paper systematically reviews their major practices and practical achievements in terms of data foundations,model libraries,and business applications,and summarizes typical experience in three aspects:constructing a sky-space-land-water-project integrated monitoring and perception system,developing specialized models,and establishing information platforms.The results show that the pilot irrigation districts have continuously improved their multi-element sensing networks by integrating existing facilities,promoting data sharing,and adding monitoring stations.Specialized models have been developed and applied to meet the core needs of water-supply security,agricultural water conservation and efficiency improvement,and safe engineering operation,facilitating the deep integration of model computation,business processes,and management decision-making.Based on irrigation methods,water source types,geographical locations,and business needs,technical modes for digital twin construction are proposed for five types of irrigation districts:gravity-fed irrigation,pumping irrigation,mixed irrigation,polder irrigation,and pipeline irrigation.The construction priorities for business platforms,sensing systems,and specialized models are identified for each type of irrigation district.Furthermore,in light of the current needs for modernizing irrigation districts,development pathways are proposed,including adhering to demand-driven development,consolidating data foundations,enhancing model adaptability,integrating water conservation and efficiency improvement,and strengthening AI integration,to provide a reference for the digital and intelligent upgrading of irrigation district projects nationwide during the 15th Five-Year Plan period.
