今年前四个月北京PM2.5累计浓度同比下降11.6%
中新网北京5月16日电 (记者 陈杭)记者今天从北京市生态环境局获悉，今年1月至4月，北京市大气环境中细颗粒物(PM2.5)累计浓度为38微克/立方米，同比下降11.6%；优良天数累计104天，比去年同期增加13天；重污染天数累计1天(受外来沙尘影响)，与去年同期持平。
北京市生态环境局表示，今年前四个月，北京市在空气质量改善方面取得了积极成果。PM2.5累计浓度同比下降11.6%，说明北京市大气污染治理成效显著。同时，优良天数累计104天，比去年同期增加13天，重污染天数累计1天，与去年同期持平，表明北京市空气质量得到了持续改善。
据了解，北京市政府采取了一系列有力措施，以改善空气质量。其中包括加强工业污染源治理，推动能源结构调整，加大公共交通基础设施建设，优化城市交通布局等。此外，北京市还加强了区域大气污染协同治理，与周边省市共同推进大气污染防治工作。
北京市生态环境局表示，尽管取得了明显成效，但北京市空气质量仍面临挑战。下一步，北京市将继续加大大气污染防治力度，坚决打好蓝天保卫战，努力提升人民群众空气质量获得感。

**News Content:** Beijing’s PM2.5 accumulated concentration has decreased by 11.6% year-on-year in the first four months of this year.
BEIJING, May 16 (Xinhua) — (Reporter: Chen Hang) Journalists with the Beijing Branch of the Xinhua News Agency learned from the Beijing Municipal Ecological Environment Bureau that from January to April this year, the accumulated concentration of fine particulate matter (PM2.5) in the city’s atmospheric environment was 38 micrograms/cubic meter, a year-on-year decrease of 11.6%. The cumulative number of good air days reached 104, an increase of 13 days from the same period last year; the cumulative number of heavy pollution days was 1 day (affected by external sandstorms), remaining the same as the same period last year.
The Beijing Municipal Ecological Environment Bureau stated that significant progress has been made in improving air quality in the city during the first four months of this year. The year-on-year decrease of 11.6% in the accumulated concentration of PM2.5 indicates that the governance of air pollution in Beijing has yielded remarkable results. Furthermore, the accumulated 104 good air days, 13 more than last year, and the steady number of 1 day with heavy pollution, compared to the same period last year, suggest that the city’s air quality continues to improve.
It is understood that the Beijing municipal government has implemented a series of effective measures to improve air quality. These include strengthening the governance of industrial pollution sources, promoting energy structure adjustments, increasing the construction of public transportation infrastructure, and optimizing urban transportation layouts. In addition, Beijing has also strengthened regional coordinated governance of air pollution, working together with surrounding provinces and cities to advance the prevention and control of air pollution.
The Beijing Municipal Ecological Environment Bureau said that although significant achievements have been made, the city’s air quality still faces challenges. In the next step, Beijing will continue to strengthen efforts in preventing and controlling air pollution, resolutely fight the battle for blue skies, and strive to enhance the public’s sense of achievement in air quality.
