在福建省龙岩市永定区，一条溪流的变迁见证着治水理念的深刻变革。从村支书20年的独自坚守，到如 今近千名"群众河长"的集体巡护；从单纯防洪保安，到发展"水经济"、共享生态红利……永定以"河长 制"拧紧责任链条，用"智慧水网"守护安澜，一幅人水和谐的现代画卷，正在绿水青山间铺展。 一张"责任网"：全民皆"河长"，治水到"末梢" 一条"转化链"：碧水流金，生态红利惠及万家 治水的成效，最终要落在百姓的幸福感与获得感上。永定深挖"水文章"，积极探索水生态产品价值转化 路径。 南江村的蜕变是最好的证明。通过系统治理，南江溪焕发新生，与周边土楼古村落联动，成功打造为省 级水利风景区。清澈的溪流吸引了游客，催生了特色民宿、滨水步道、亲子营地等业态。村民人均年收 入较治理前增长18%，"绿水青山"真正变成了"金山银山"。 此外，在龙湖国家级水利风景区，永定打造了渔生态主题园，并完成了2宗水权交易。水资源，正在以 更多元的方式，转化为实实在在的发展优势和民生福祉。 冬日暖阳下，永定区湖坑镇南江村溪水潺潺，映衬着古老土楼。村支书、村级河长江道明带领村民巡河 的身影，已成为日常一景。"过去是我一个人干着急，现在全村都是'眼睛'和' ...

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].

"通过布设覆盖水位、水量等指标的全要素感知体系，实现了康门水库大坝安全在线监测与动态风险预 警。"工作人员介绍道。这一实践正是杭州全力打造水利物联感知网络的生动缩影。康门水库的全要素 感知建设实践，正是杭州全力打造水利物联感知网络的生动缩影。 在水利部试点项目青山水库智能大坝建设中，技术突破更亮眼。通过8颗水利一号组网卫星，测量周期 由传统的12天提升到2天，雷达成像技术可以不受云层、光线影响，数据获取"全天无休"，实现亚毫米 级变形监测和分米级水域监管。 如果说数字孪生是水利工程的"智慧大脑"，感知网络便是连接物理世界与数字空间的"神经末梢"。杭州 充分运用新一代信息技术，建立"天基、空基""落地雨""洪水演进"监测预报防线，夯实"天空地水工"监 测感知一张网，为水利工程高保真建设运行提供有力算据保障。 四预一体化 指导全方位防洪调度 商报讯（记者 蔡杭吉 通讯员 冯晴颖 ）钱塘江畔，数字浪潮正绘就杭州水脉治理新图景。昨天，水利部 在杭州召开数字孪生水利建设现场会，现场考察萧山枢纽、之江水文站、西江塘等数字孪生水利建设成 果。会场外，杭州康门水库全要素构建现代化水库管理矩阵数据监测体系、西险大塘数字孪生系统 ...
