从“点上盆景”到“面上风景” 数字孪生水利绘就现代化新图景

Core Viewpoint - The article highlights the comprehensive implementation of a digital twin system in water management in Zhejiang, which enhances the efficiency and precision of water resource management through real-time data monitoring and analysis [1][2][5]. Group 1: Digital Twin System Implementation - The digital twin system creates a virtual representation of physical water management entities, enabling real-time monitoring, analysis, and optimization [2]. - Zhejiang has established a "1+3+N" planning framework for digital twin water management, which includes a comprehensive sensing network and a provincial digital twin platform [2]. - As of now, 69 digital twin projects have been successfully implemented, marking a significant transition from initial breakthroughs to broader enhancements [2]. Group 2: Enhanced Monitoring and Response - The average density of rainfall stations in Zhejiang has reached one station per 6.2 square kilometers, ensuring comprehensive coverage for timely flood warnings [3][4]. - The efficiency of flood warnings has improved by 50%, with the response time reduced from 30 minutes to 15 minutes [3]. - The integration of various resources, including satellite, radar, and ground monitoring, has created a high-precision sensing network for effective water management [4]. Group 3: Water Resource Management Success - During a drought in August 2024, the digital twin water network model enabled the effective management of water resources, resulting in the delivery of 7.54 million cubic meters of water to alleviate drought conditions [5]. - Ningbo has established over 14,000 monitoring points to create a smart water network that optimizes water supply and management across various water sources [6]. - The digital twin system in Ningbo has maintained a water supply guarantee rate of 99.8% during drought conditions by optimizing reservoir and water plant operations [6]. Group 4: Future Directions - The ongoing development of the digital twin technology aims to enhance the resilience, intelligence, and public benefit of modern water networks, with plans to share successful practices nationwide [6].
