Core Viewpoint - The ecological flow determination and assurance in river and lake ecosystems are essential for environmental protection, with the Pearl River Commission implementing comprehensive plans for 135 inter-provincial rivers to ensure ecological flow management [1][2]. Group 1: Systematic Inspection - The Pearl River Commission has conducted a thorough inspection of over 460 existing water conservancy and hydropower projects to clarify the status of ecological flow determination and ensure consistency and compliance with approved results [1][2]. - This systematic inspection aims to identify foundational work, existing issues, and key tasks, providing precise data for future ecological flow determination and assurance efforts [1]. Group 2: Coordinated Goal Setting - Following the inspections, the Commission has established ecological flow targets based on river management requirements, hydrological characteristics, and ecological protection needs, ensuring alignment with upstream and downstream projects [2]. - The Commission has completed ecological flow determinations for seven major hydropower projects, ensuring that all established projects within the permitted water withdrawal management scope have defined ecological flows [2]. Group 3: Collaborative Governance - The Pearl River Commission has enhanced communication with relevant departments to clarify work requirements and guide provinces in accelerating the ecological flow determination for existing inter-provincial water conservancy projects [2]. - The Commission is focused on addressing issues related to undetermined ecological flows and ensuring coordination between upstream and downstream projects through rigorous review and feedback mechanisms [2]. Group 4: Future Directions - The Pearl River Commission has completed all tasks related to ecological flow inspection and determination, establishing a comprehensive ecological flow assurance target system for the Pearl River basin [3]. - Future efforts will focus on deepening ecological flow release and scheduling, monitoring and early warning systems, and evaluation to ensure the effective implementation of ecological flow objectives [3].

Core Viewpoint - The Songliao Commission has completed the ecological flow verification work for cross-provincial rivers and existing water conservancy and hydropower projects in the Songliao Basin, focusing on ecological flow targets and management responsibilities [1][2] Group 1: Ecological Flow Verification - The verification work covered 126 cross-provincial river control sections and existing water conservancy and hydropower projects, ensuring compliance with the Ministry of Water Resources' requirements [1] - A total of 49 cross-provincial rivers and 81 control sections have had their ecological flow targets verified or optimized, with management requirements for ecological flow scheduling established [1] - The verification process involved on-site investigations of key rivers with significant water use conflicts and ecological issues, such as the Holin River and Uligumiren River [1] Group 2: Future Plans and Implementation - The Songliao Commission plans to develop comprehensive ecological flow guarantee implementation plans for cross-provincial rivers, guiding the orderly determination and safeguarding of ecological flow in various provinces [2] - The focus will be on creating an integrated ecological flow guarantee system that connects upstream and downstream river systems, ensuring the health of rivers and lakes [2] - The verification of ecological flow targets for 93 existing water projects across four provinces has been conducted, providing a basis for scientifically determining ecological flow goals [2]

Core Viewpoint - The establishment and assurance of ecological flow in rivers and lakes is crucial for the protection of ecological environments, with the Pearl River Water Resources Commission completing plans for 135 inter-provincial rivers [1][2] Group 1: Implementation and Oversight - The Ministry of Water Resources has prioritized the completion of ecological flow assurance plans for inter-provincial rivers as a key task for 2025 [1] - The Pearl River Water Resources Commission has formed a specialized working group to ensure high-quality completion of these tasks, involving technical experts and clear task assignments [2] - The commission has conducted thorough investigations and discussions with provincial authorities to gather feedback and ensure consistency across different water systems [2] Group 2: Technical and Scientific Approach - The commission emphasizes the scientific and practical aspects of determining ecological flow, ensuring that assessments are tailored to the specific conditions of each river basin [1][2] - The ecological flow assurance plans include detailed control measures, monitoring, and evaluation responsibilities, covering five major river systems [2] - The results have been revised based on feedback from meetings and are now submitted for review by the Ministry of Water Resources [3]

Core Viewpoint - The "Beautiful Rivers and Lakes Protection and Construction Action Plan (2025-2027)" aims to enhance the ecological environment of rivers and lakes in China, with specific targets and measures outlined for achieving this goal by 2027 and beyond [1]. Group 1: Conditions for Beautiful Rivers and Lakes - Beautiful rivers and lakes should have stable water sources, good water flow, and effective ecological water use to ensure "having rivers and water" [2]. - The ecological environment and biodiversity must be maintained or restored, ensuring the presence of indigenous species and achieving "having fish and grass" [2]. - Pollution control is essential, with water quality improving to a good standard, meeting public recreational needs, and resolving ecological issues to achieve "harmony between people and water" [2]. Group 2: Goals and Targets - By 2027, the construction rate of beautiful rivers and lakes is expected to reach approximately 40%, with significant progress by 2030 and basic completion by 2035 [2]. - The action plan includes 15 specific targets focusing on water environment governance, ecological water use assurance, and ecological protection and restoration [3]. Group 3: Water Environment Governance - The action plan emphasizes the importance of managing pollution sources, particularly through the establishment of a monitoring and regulatory system for pollution outlets by 2027 [4]. - It aims to significantly improve urban sewage treatment efficiency and achieve over 60% control of rural sewage by 2027, while eliminating rural black and odorous water bodies [4]. Group 4: Ecological Flow Assurance - The plan specifies requirements for ensuring ecological flow, which is crucial for maintaining river ecosystems, with a focus on cross-province key rivers and lakes by 2027 [5]. Group 5: Ecological Protection and Restoration - The action plan aims to enhance the health of river and lake ecosystems, with specific assessments and mechanisms for ecological compensation established by 2027 [6]. Group 6: Funding and Technology Support - The plan highlights the need for technological innovation in water ecological environments and emphasizes the role of central finance in supporting these initiatives [7]. - It encourages local finance and social capital to increase investment, promoting various models for public-private partnerships in ecological protection and construction [7].
