[Objective]Smart water conservancy is one of the implementation paths to promote the high-quality development of water conservancy in the new stage,and the construction of digital twin basin is the core and key to realizing smart water conser-vancy.To improve the usability,scalability,reusability and maintainability of the water conservancy model in the construction of the digital twin platform of the Ministry of Water Resources,[Methods]according to the requirements of"standardization,modu-larization,and cloud service"for the construction of the digital twin basin model platform,using the idea of"divide and conquer+integration",based on component technology,workflow technology,SOA architecture and container technology,the digital twin ba-sin model platform of the Ministry of Water Resources is constructed.The platform supports the componentized encapsulation and process-building function of hydrological models and intelligent identification models and provides model-sharing and computing services externally through the micro-service form.[Results]The platform design's rationality and the application's feasibility have been verified,through the key R&D project demonstration areas—Tunxi Basin and Baihetan Reservoir,"flood forecasting-warning-scheduling"business application and the deformation monitoring business application of project management scope.[Conclusion]The research result can provide some technical support for constructing and applying the digital twin basin model platform.
