Core Viewpoint - The article discusses the successful implementation of water replenishment in the Grand Canal, highlighting the ecological and economic benefits resulting from the restoration of water flow and the development of new industries along the canal [1][5]. Group 1: Water Replenishment and Management - The Grand Canal has achieved continuous water flow for four consecutive years since 2022, with the replenishment task for 2025 starting in February and completed by July [1][2]. - The replenishment focuses on the northern sections of the Grand Canal, utilizing multiple water sources including the Yangtze River, Yellow River, and local rainwater, with a total of 7.88 billion cubic meters of water supplied, exceeding the planned amount by 142% [3][4]. - Advanced monitoring technologies, including drones and real-time water flow measurement, are employed to ensure effective water management and distribution along the canal [4][8]. Group 2: Ecological and Economic Impact - The restoration of water flow has led to improved water quality and increased water surface area in the northern sections of the Grand Canal, with a total infiltration of 5.31 billion cubic meters from 2022 to 2024 [6][7]. - The revitalization of the canal has spurred new economic activities, such as rural tourism and outdoor sports, enhancing local livelihoods and promoting cultural heritage [6][7]. - The initiative aims to create a sustainable water management system that balances irrigation needs and ecological restoration, with a focus on long-term benefits for the surrounding communities [8][9].
