Core Viewpoint - The transformation of Lianjiang from a heavily polluted river to an ecological river highlights the effectiveness of systematic governance and innovative institutional frameworks in environmental protection [1][4][6]. Group 1: Background and Historical Context - Lianjiang, once known as the "mother river" of the Chaoshan region, faced severe pollution due to industrial waste and untreated sewage discharge since the 1990s, leading to a significant ecological crisis [2]. - The river's water quality deteriorated to below Class V standards for several years, with some sections losing aquatic life entirely [2]. Group 2: Governance and Institutional Innovation - The key to Lianjiang's restoration lies in the implementation of the river chief system, which established a multi-tiered responsibility framework across provincial, municipal, and local levels [3]. - This system transformed the role of river chiefs into accountable guardians of water quality, effectively addressing the long-standing issues of fragmented governance and unclear responsibilities [3]. Group 3: Comprehensive Management Approach - The governance strategy combined source reduction, process control, and end-of-pipe treatment, including shutting down polluting enterprises and constructing wastewater treatment facilities [4]. - The approach also involved comprehensive management of tributaries and pollution outlets, alongside ecological restoration efforts to rebuild the river's ecosystem [4].

Core Viewpoint - The article discusses the long-term efforts and challenges in the ecological restoration and pollution control of Taihu Lake, highlighting the transition from severe pollution to improved water quality over 30 years, with a focus on collaborative governance and innovative solutions to address the complex pollution issues [1][4][19]. Group 1: Water Quality Improvement - Taihu Lake's water quality has improved from Class V to Class III over 30 years, establishing itself as a benchmark for large lake nutrient management internationally [1]. - The average depth of Taihu Lake is 1.9 meters, making it a shallow lake with limited self-purification capacity, which complicates pollution management [2][3]. - In 2022, the population in the Taihu basin accounted for 4.8% of the national total, and the regional GDP represented 9.8% of the national GDP, indicating significant economic activity in the area [3]. Group 2: Pollution Sources and Challenges - The shallow nature of Taihu Lake allows sunlight to reach the bottom, promoting blue-green algae growth, which is exacerbated by industrial pollution and urbanization in the surrounding areas [2][3]. - The 2007 blue-green algae outbreak highlighted the complexity of pollution sources, leading to a shift in focus from ecological restoration to source control and pollution interception [4][6]. - The Taihu basin has faced severe pollution, with 67% of monitored points classified as inferior Class V water quality, indicating a critical need for effective pollution control measures [3]. Group 3: Governance and Collaborative Efforts - The governance of Taihu Lake has evolved from fragmented management to a more coordinated approach, with the establishment of inter-agency collaboration and joint initiatives among cities [15][16]. - The introduction of the Taihu Lake water pollution prevention office in 2009 marked a significant step towards unified management of water quality across different jurisdictions [16]. - Recent initiatives include the establishment of cross-regional cooperation mechanisms and joint law enforcement efforts to tackle pollution effectively [17][18]. Group 4: Economic Transformation and Sustainable Development - The shift from high-pollution industries to green, low-carbon economic models is crucial for the sustainable development of the Taihu region, with significant reductions in polluting industries [12][13]. - The transformation of Zhou Tie Town from a chemical industry hub to an eco-friendly area demonstrates the potential for economic growth while prioritizing environmental protection [12][13]. - By 2024, the region has seen a stable GDP growth rate while improving water quality, showcasing a successful model of balancing economic development with ecological sustainability [14].
