2025年我国空气质量创下有监测记录以来最好水平 “十四五”时期蓝天保卫战取得历史性成就

Core Insights - The Ministry of Ecology and Environment announced that by 2025, China's air quality will reach its historical best, achieving a significant milestone in the "Blue Sky Defense War" and laying a solid foundation for the construction of a beautiful China [1] Group 1: Air Quality Improvements - By 2025, the average PM2.5 concentration in cities at or above the prefecture level is expected to reach 28.0 micrograms per cubic meter, with a good air quality day ratio of 89.3% (excluding dust influence) and heavy pollution days at only 0.9% [2] - From July 20 to October 24, 2025, the proportion of good air quality days maintained above 90% for the first time, marking a historic breakthrough [2] - Compared to 2020, concentrations of five major pollutants, including sulfur dioxide and nitrogen oxides, are projected to decrease by 15%-20% by 2025, while ozone levels are expected to stabilize [2] Group 2: Regional Achievements - Significant regional improvements are noted, with PM2.5 concentrations in the Beijing-Tianjin-Hebei region and the Fenwei Plain decreasing by 27.7% and 32.1%, respectively [2] - These two regions, which account for less than one-sixth of the total number of cities, contributed nearly 50% of the national air quality improvement [2] - Linfen in Shanxi province saw the largest improvement, with PM2.5 concentrations dropping by 46.5% compared to 2020 [2] Group 3: Economic Growth and Environmental Protection - During the "14th Five-Year Plan" period, national GDP is expected to grow by 30% while PM2.5 concentrations decrease by 20%, with the number of cities meeting air quality standards increasing from 206 to 246 [3] - By 2025, the average PM2.5 concentration in 29 cities with GDP exceeding 1 trillion yuan is projected to be 27.8 micrograms per cubic meter, better than the national average [3] - Beijing's PM2.5 concentration has decreased from 89.5 micrograms per cubic meter in 2013 to 27 micrograms per cubic meter, achieving a significant milestone in air pollution control [3] Group 4: Strategic Measures - The success of the "Blue Sky Defense War" is attributed to three key strategies: "transformation," "reduction," and "treatment" [4] - Structural optimization focuses on industrial, energy, and transportation adjustments, including the elimination of 12 million tons of outdated production capacity and nearly 30 million high-emission old vehicles [4] - Pollution control efforts include deep governance in key industries, achieving ultra-low emissions for 1.7 million kilowatts of coal power units, and a clean heating rate of 83% in northern regions [4] - Enhanced regulatory capabilities include revising air quality standards and establishing a comprehensive monitoring network with satellite support [4] Group 5: Future Directions - In the "15th Five-Year Plan" starting this year, the Ministry of Ecology and Environment will focus on new air quality standards and the reduction of PM2.5 concentrations, continuing to promote structural transformation and precise governance [5]
