近日，生态环境部发布数据显示，长江经济带地表水优良水质（Ⅰ—Ⅲ类）断面比例已提升至96.5%，创历史新高。这一成果标志着长江大保护战略实施以来，流域水环境质量显著改善。自2016年国家启动长江经济带发展战略，强调‘共抓大保护、不搞大开发’以来，沿江11省市协同推进污染治理、生态修复和绿色发展。通过关停高污染企业、整治入河排污口、建设污水处理设施以及实施岸线复绿等举措，长江干流连续多年保持Ⅱ类水质，主要支流水质也稳步向好。此外，跨区域生态补偿机制和智慧监测体系的建立，进一步提升了流域综合治理能力。优良水质比例的持续上升不仅保障了4亿多人口的饮水安全，也为长江经济带高质量发展提供了坚实的生态支撑。未来，还需持续强化源头防控、完善法规制度、推动绿色转型，确保一江清水绵延后世。
Recently, China’s Ministry of Ecology and Environment reported that the proportion of surface water with good quality (Class I–III) in the Yangtze River Economic Belt has risen to 96.5%, reaching a historic high. This milestone reflects significant improvements in water quality since the launch of the Yangtze River Protection Strategy. Since 2016, when the national government initiated the Yangtze River Economic Belt development plan with the principle of ‘jointly protecting the river without large-scale development,’ 11 provinces and municipalities along the river have collaborated on pollution control, ecological restoration, and green development. Measures such as shutting down heavily polluting factories, rectifying sewage discharge outlets, building wastewater treatment facilities, and restoring riverbank vegetation have led to the main stem of the Yangtze maintaining Class II water quality for several consecutive years, with major tributaries also showing steady improvement. Additionally, cross-regional ecological compensation mechanisms and smart monitoring systems have enhanced integrated watershed governance. The rising share of high-quality water not only safeguards drinking water for over 400 million people but also provides a solid ecological foundation for the region’s high-quality development. Moving forward, continued efforts in source control, legal framework refinement, and green transformation will be essential to ensure the Yangtze remains clean for generations to come.
