Abstract：Based on digital twin theory,a multidimensional cognitive framework for irrigation districts is constructed for the first time from the perspective of the water network system,providing theoretical support for the digital transformation of complex irrigation systems.By deconstructing the three-dimensional coupling relationship among the engineering facility chain,water resource system network,and management entities,five core characteristics of the irrigation water network are proposed:hierarchical complexity,dynamic coupling,functional integration,regional heterogeneity,and operational synergy.The connotation of digital twin irrigation districts is further analyzed from three dimensions:characteristics,functions,and collaboration.This study breaks through the traditional management paradigm of irrigation districts and,oriented toward business objectives such as safe operation of infrastructure,scientific water dispatching,automated and intelligent control,efficient collaborative management,agile emergency response,and proactive and convenient services,establishes a five-stage closed-loop optimization path:"digital scenarios → intelligent simulation →precise decision-making → automated control → quantitative evaluation".An intelligent agent framework for digital twin irrigation districts is developed,with core technologies including three-dimensional sensing,soil moisture forecasting,dynamic assessment,water volume scheduling,and remote control,and key functions such as water transfer optimization,water conveyance simulation,intelligent control,precise water distribution,and efficient water use.This framework realizes a paradigm shift in irrigation water network management from"experience-driven"to"data-mechanism-knowledge-driven",offering a replicable and scalable model for the application of digital twin technology in complex irrigation systems.It holds significant strategic value for ensuring national food security and the sustainable utilization of water resources.
