中新社北京4月8日电 (记者 陈杭)北京市生态环境局于8日发布消息，随着春季的到来，首都北京正面临沙尘天气的频繁侵扰。据统计，今年迄今为止，北京地区已经历了三次强度较大的沙尘天气，对当地空气质量造成显著影响。
据北京市生态环境局介绍，这三次沙尘天气分别发生在春季的不同时段，每次沙尘过境都导致空气中颗粒物浓度显著上升，对市民的生活和健康构成潜在威胁。北京市政府对此高度重视，已启动相应的应急预案，加强空气质量监测，并与周边地区协同应对，以减轻沙尘对城市环境和市民生活的影响。
专家分析，春季是北京地区沙尘天气的高发期，主要原因是春季气温回升、地表解冻，加之北方干旱地区风力增强，易于引发沙尘扬起。为应对这一现象，北京已加大了植树造林和沙漠化治理力度，旨在从源头上减少沙尘源，改善生态环境。
北京市生态环境局呼吁市民在沙尘天气期间，尽量减少户外活动，做好个人防护，同时倡导全社会共同参与，加强环保意识，共同守护北京的蓝天白云。
随着科技的发展，北京市也在探索利用科技手段预测和防控沙尘天气，以期在未来能更有效地减轻沙尘对城市的影响，保障市民的生活质量。

News Title: “Beijing Has Endured Three Severe Sandstorms This Year, Raising Concerns Over Spring Air Quality”

Beijing, April 8 (Xinhua) – The Beijing Municipal Ecology and Environment Bureau announced on Thursday that the capital is experiencing a recurrent intrusion of sandstorms as spring arrives. According to statistics, the city has been hit by three significant sandstorms so far this year, significantly impacting local air quality.
The bureau explained that these sandstorms occurred at different times during the spring season, each leading to a notable increase in airborne particle concentrations, posing potential threats to residents’ lives and health. The Beijing government has taken this situation seriously, initiating emergency response plans, intensifying air quality monitoring, and collaborating with neighboring regions to mitigate the impact of sandstorms on the urban environment and citizens’ lives.
Experts analyze that spring is the peak period for sandstorms in the Beijing area. The primary reasons are the rising temperatures, thawing ground, and increased winds in the drought-prone northern regions, which contribute to sand suspension. To address this issue, Beijing has intensified efforts in afforestation and desertification control, aiming to reduce sand sources and improve the ecological environment.
The Beijing Municipal Ecology and Environment Bureau advises citizens to minimize outdoor activities during sandstorm periods and take personal protective measures. It also advocates for public participation and enhanced environmental awareness to jointly protect Beijing’s blue skies and white clouds.
With the advancement of technology, the city is exploring scientific methods for predicting and controlling sandstorms, hoping to more effectively alleviate their impact on urban life in the future and ensure the quality of life for residents.
