千年都江堰，何以持续“生长”？丨水润蜀乡

Core Viewpoint - The Dujiangyan irrigation system, an ancient water conservancy project, has evolved into a modern and efficient water management system, integrating traditional wisdom with contemporary development practices [1][4]. Group 1: Maintenance and Modernization - The annual maintenance, known as "yearly repair," is crucial for the longevity of the Dujiangyan irrigation system, focusing on tasks such as dredging and equipment upkeep [6][4]. - The maintenance work has become more sophisticated, incorporating modern techniques such as drone inspections and digital management systems to enhance operational efficiency [6][4]. Group 2: Water Resource Management - The Dujiangyan irrigation area covers 41 counties in 8 cities, serving over 30 million people, making it one of China's three major irrigation districts [7][8]. - The modernization of the irrigation system has reduced water distribution response times from hours to minutes, with a precision control of ±5% in water allocation [8][7]. - The digital twin system allows for data-driven water resource management, significantly improving flood risk predictions and irrigation efficiency [8][7]. Group 3: Hydrological Monitoring - The Dujiangyan hydrological station has been upgraded to enhance monitoring capabilities, with data now uploaded every five minutes using advanced technologies [11][12]. - New radar systems have been implemented to monitor rainfall and river flow, improving the ability to predict and respond to extreme weather events [12][11].
