珠江流域片跨省河流上已建水利水电工程生态流量确定工作完成

Core Viewpoint - The Pearl River Water Resources Commission has completed a comprehensive assessment of ecological flow for over 460 existing water conservancy and hydropower projects in the Pearl River Basin, establishing a robust framework for ecological flow management and resource allocation [1][2]. Group 1: Ecological Flow Management - The determination and assurance of ecological flow in rivers and lakes are fundamental for environmental protection [1]. - The Commission has developed implementation plans for ecological flow assurance across 135 inter-provincial rivers, transitioning from fragmented management to a systematic approach [1][2]. - A thorough review of existing hydropower projects has clarified the status of ecological flow determinations, providing a precise basis for future management efforts [1]. Group 2: Technical and Regulatory Framework - The Commission has established ecological flow standards based on hydrological characteristics, environmental protection requirements, and operational capabilities of the projects [2]. - Seven major hydropower projects have had their ecological flow determined, ensuring compliance within the permitted water extraction management framework [2]. - Ongoing communication with relevant authorities aims to expedite the ecological flow determination process for existing projects, addressing inconsistencies and enhancing collaborative efforts [2]. Group 3: Future Initiatives - The Commission plans to deepen efforts in ecological flow release, monitoring, and assessment, aiming to transition from setting targets to precise implementation [2].
