北京APEC蓝如何变成常态蓝？生态环境局新闻发言人带来一张图

Core Viewpoint - Beijing has successfully transformed its air quality from "APEC Blue" to "Regular Blue" through meticulous pollution control efforts, achieving significant reductions in PM2.5 levels from 2013 to 2025 [1][2] Group 1: Air Quality Improvement - The PM2.5 concentration in Beijing has significantly decreased, with the 2025 distribution map showing a shift from predominantly red (high pollution) in 2013 to green (low pollution) across all regions [1] - The improvement in air quality has led to increased public satisfaction, making blue skies a common experience for residents rather than a luxury [1] Group 2: Pollution Control Strategies - Beijing has implemented a series of action plans, including the Clean Air Five-Year Action Plan and the Blue Sky Defense Three-Year Action Plan, focusing on precise pollution control measures [1] - The city has identified 23 key local pollution sources contributing over 0.1 micrograms of PM2.5 and has developed targeted measures for each source to enhance green reduction potential [2] Group 3: Technological Innovations - The city has established an integrated air quality monitoring network utilizing over 200 satellite remote sensing units, 320 enterprise online monitoring systems, and numerous ground monitoring stations to achieve precise pollution source analysis and dynamic tracking [2] - Advanced technologies, including artificial intelligence, are employed for intelligent early warning systems, ensuring comprehensive monitoring without unnecessary disruptions [2] Group 4: Regional Cooperation - Beijing collaborates closely with surrounding provinces and cities to create a unified pollution control mechanism, aligning planning and standards for coordinated emission reductions [2] - The improvement in Beijing's air quality is also attributed to the simultaneous enhancement of air quality in the surrounding regions, demonstrating the effectiveness of regional governance [2]
