Group 1 - The current flood season poses significant challenges for flood prevention tasks in many areas, with some regions neglecting flood control efforts during small watershed management, leading to safety hazards and adverse impacts on local flood prevention work [1] - Small watershed management is a comprehensive and systematic project, where flood prevention during the flood season is crucial for the safety of people's lives and property, as well as the effectiveness and long-term stability of the entire management project [1] - Flood prevention should not be conducted in isolation but should be integrated with various measures such as water conservancy law enforcement, ecological restoration, soil and water conservation, and comprehensive water resource utilization [1] Group 2 - Small watersheds often have significant topographical variations and uneven surface coverage, leading to rapid runoff formation after rainfall, which can trigger sudden disasters like flash floods and mudslides [2] - During small watershed management, it is essential to consider the natural geographical features and historical hydrological data of the watershed to design appropriate drainage systems, flood control dams, and diversion channels [2] - Establishing and improving real-time monitoring and early warning systems for rainfall, water conditions, and disasters is crucial for timely information collection, transmission, and analysis to support emergency responses [2] Group 3 - To ensure the long-term effectiveness and systematic nature of flood prevention efforts, it is necessary to strengthen institutional frameworks and technological support [3] - A sound regulatory framework and responsibility mechanism for small watershed management should be established, clarifying the flood prevention responsibilities of various government levels, relevant departments, and social entities [3] - The introduction of modern information technologies, such as remote sensing monitoring, geographic information systems (GIS), and artificial intelligence prediction models, can enhance the scientific and intelligent level of flood prevention decision-making [3]

Group 1 - The core viewpoint of the article emphasizes the comprehensive promotion of river protection and management, highlighting the need for integrated water resource utilization and the development of hydropower, pumped storage, and inland shipping [1] - The document outlines significant achievements in China's water resource utilization, including the Baihetan Hydropower Station's cumulative power generation exceeding 196 billion kilowatt-hours, which equates to saving over 59 million tons of standard coal and reducing carbon dioxide emissions by over 160 million tons [1] - The article notes the rapid growth of inland shipping, with the annual cargo volume on the Yangtze River increasing from less than 2 billion tons to over 3.5 billion tons in the past decade, leading the global inland shipping sector [1] Group 2 - The continuous improvement of the policy framework provides solid support for comprehensive water resource utilization, with the 2021 plan aiming to establish a modern pumped storage industry by 2035 to meet the demands of high-proportion renewable energy development [2] - The article identifies challenges in policy coordination and market mechanisms, such as unreasonable water rights allocation and high costs of advanced technology, which hinder effective water resource management [2] - It suggests that integrating policy drivers with market mechanisms can unlock the potential for comprehensive water resource utilization, emphasizing the need for strict water resource management assessments and diversified financing channels [2] Group 3 - The article discusses the importance of technology and innovation in enhancing water resource utilization, advocating for targeted research and the application of advanced technologies like nanofiltration and smart water meters [3] - It highlights the necessity of breaking down administrative barriers and establishing collaborative governance mechanisms across regions and departments to optimize water resource management [3] - The focus is on achieving scientific allocation and efficient use of water resources in agriculture, industry, and urban settings through effective measures [3]
