珠江水利委员会全面完成跨省河流上已建水利水电工程生态流量确定工作

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].
