Core Viewpoint - The article emphasizes the ecological protection and high-quality development of the Yellow River, highlighting the significant improvements in water quality and sediment reduction over the years, as well as the collaborative efforts across various regions to restore and protect this vital waterway [1][7][54]. Group 1: Ecological Improvements - The sediment concentration in the Yellow River has decreased from an average of 27.5 kg per cubic meter (1952-2020) to 5.76 kg by 2024 [5]. - The Yellow River has achieved continuous flow for 26 years and has maintained a stable water quality of Class II for three consecutive years, with over 90% of the river basin classified as good water quality [7][8]. - The upstream regions have implemented measures to reduce sediment input, including the construction of over 50,000 sediment retention dams that have collectively trapped 7.4 billion tons of sediment [25]. Group 2: Regional Strategies - In the upstream areas, ecological protection and water source conservation are prioritized, while the middle reaches focus on soil and water conservation to enhance water quality [14][26]. - The middle reaches, particularly the Fen River, have seen significant improvements in water quality due to enhanced industrial wastewater treatment and strict pollution controls [30][35]. - The downstream regions have transformed previously degraded riverbanks into productive agricultural areas, showcasing successful ecological restoration efforts [42]. Group 3: Legislative and Collaborative Efforts - The implementation of the "Yellow River Protection Law" has established a unified water and sediment management system, reversing the historical trend of frequent river flow interruptions [54]. - Major ecological projects, such as the "Three North" program and the establishment of national parks, are being actively pursued to ensure comprehensive protection of the Yellow River [50][52]. - The collaborative approach across provinces and regions has shifted from isolated efforts to a unified strategy for the protection of the Yellow River [58].
