今年前四月北京累计PM2.5浓度同比下降超11%
中新社北京5月16日电 (记者 陈杭)记者16日从北京市生态环境局获悉，今年1月至4月，北京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%。这一数据表明，北京市在改善空气质量方面取得了显著成效。
近年来，北京市政府采取了一系列有力措施，以减少PM2.5等污染物的排放。这些措施包括加强工业污染源治理、优化能源结构、推广新能源汽车、提高建筑工地管理水平等。这些努力得到了回报，今年前四个月的数据显示，北京的空气质量有了明显改善。
此外，今年前四月，北京优良天数累计104天，同比增加13天。这表明北京市在提升空气质量的同时，也增加了蓝天数量，让市民享受到了更好的生活环境。
然而，受外来沙尘影响，北京的重污染天数仍有1天，同比减少6天。尽管如此，这一数据仍然显示出北京市在应对沙尘暴等自然灾害方面的努力。
总的来说，今年前四月北京市PM2.5浓度同比下降超过11%，这一成果来之不易，体现了北京市政府和社会各界共同努力的结果。未来，北京市将继续加大环境保护力度，努力实现空气质量的根本改善，为市民创造更加宜居的生活环境。

**Title:** Beijing’s Air Quality Improves Markedly in First Four Months, Days with Severe Pollution Down by 6
**Keywords:** Beijing, Decline in PM2.5, Ecological Environment Improvement
**News Content:** Beijing has seen a significant reduction in PM2.5 concentration in the first four months of the year, down over 11% from the same period last year.
BEIJING, May 16, Xinhua News Agency (Reporter Chen Hang) — According to the Beijing Municipal Ecological Environment Bureau on May 16, from January to April this year, the cumulative concentration of fine particulate matter (PM2.5) in Beijing’s atmospheric environment was 38 micrograms/cubic meter, a decrease of 11.6% year-on-year. This data indicates that significant progress has been made in improving air quality in Beijing.
In recent years, the Beijing municipal government has taken a series of effective measures to reduce emissions of pollutants such as PM2.5. These measures include strengthening the governance of industrial pollution sources, optimizing energy structure, promoting new energy vehicles, and improving the management level of construction sites. These efforts have paid off, with the data from the first four months of this year showing a noticeable improvement in Beijing’s air quality.
Additionally, from January to April this year, Beijing had a total of 104 good air quality days, an increase of 13 days year-on-year. This indicates that while improving air quality, Beijing has also increased the number of blue sky days, providing residents with a better living environment.
However, affected by external sandstorms, Beijing still had 1 day with severe pollution, 6 days fewer than the same period last year. Despite this, the data still shows the efforts of Beijing in dealing with natural disasters such as sandstorms.
Overall, the decrease of over 11% in PM2.5 concentration in the first four months in Beijing was not easy and reflects the joint efforts of the Beijing municipal government and all sectors of society. In the future, Beijing will continue to strengthen environmental protection efforts, striving for fundamental improvements in air quality and creating a more livable environment for residents.
