Abstract
The construction of digital twin irrigation districts is an essential component of smart water conservancy development and a key measure to promote the digital transformation of rural water conservancy and cultivate new quality productive forces.Taking the construction of the digital twin Pishihang irrigation district as an example,this paper systematically explores its implementation pathway and outcomes.Following"demand-driven,application-oriented,digitally empowered,and capacity-enhancing"overall principles of smart water conservancy and aiming for solutions that are"effective,practical,and user-friendly",the Pishihang irrigation district has advanced as a pilot in digital twin irrigation development.Building on its existing informatization foundation,the district has improved its comprehensive data acquisition infrastructure for rainfall,hydrology,engineering status,agricultural activities,and meteorological conditions,thereby reinforcing its data base.By integrating hydrological data and historical scheduling records,and developing supporting models for water demand forecasting,water resource allocation,channel flood dispatching,and water supply scheduling,a digital twin management platform has been established.This platform enhances intelligent applications in key areas such as water resource allocation,water supply scheduling,and flood and drought disaster response.Through the integration of"front-end perception+data infrastructure+specialized models",relevant business processes are linked to improve"four pre"capabilities in water resource optimization,scientific water scheduling,and channel flood control.The platform's effectiveness has been analyzed across six functions:inflow forecasting,water demand prediction,pre-distribution planning,water regulation,water supply and conservation,and channel flood control,providing useful insights for the development of digital twin irrigation districts in similar contexts.关键词
