How technology boosts Beijing's air pollution governance_我的网站

怒火攻心

本报讯(海河传媒中心记者张璐璐)北京时间7月23日晚,世界乒乓球职业大联盟(WTT)冠军赛布达佩斯站落幕。中国选手未能包揽冠军,王曼昱在女单决赛中以4比2力克队友王艺迪,夺得冠军,而林高远却在随后的男单决赛中浪费六个赛点,以3比4遭日本选手张本智和逆转,丢掉冠军。与上周进行的WTT球星挑战赛不同,WTT冠军赛只设男、女单打项目比赛,且积分奖励丰厚。

(Xinhua/Sun Suying)Beijing's blue skies have become a visible sign of the city's progress in tackling air pollution, and behind that progress, digital technologies are playing an increasingly important role.
In 2025, Beijing recorded 311 days with good air quality and only one heavily polluted day, compared with 58 heavily polluted days in 2013, when the city officially began releasing PM2.5 monitoring data. The annual average PM2.5 concentration, a key indicator of air quality, fell from 89.5 micrograms per cubic meter in 2013 to 27 micrograms per cubic meter in 2025, a decline of nearly 70 percent.
The progress has drawn international attention. The United Nations Environment Programme has highlighted Beijing's experience in improving air quality as a model for other cities.
According to experts at the Beijing Municipal Ecological and Environmental Monitoring Center, the cleaner air is the result of a comprehensive system integrating environmental monitoring, scientific analysis, policymaking, regional cooperation and law enforcement -- with digital technologies now woven into every link of that chain.
MORE TARGETED APPROACH
Effective governance begins with accurate monitoring. Beijing has established a multi-level air-quality monitoring network. Figures show 35 standard monitoring stations across the city continuously measure six major pollutants, while more than 1,000 compact sensors deployed across communities and townships provide more detailed information on local air-quality variations.
The monitoring system was gradually built by the Beijing Municipal Ecological and Environmental Monitoring Center, one of China's earliest ecological and environmental monitoring institutions, responsible for monitoring Beijing's air, water, noise, soil environments and ecosystems.
The center has developed an analytical system that can identify around 125 components of PM2.5, covering most of its composition and helping researchers trace pollution sources.
"Source analysis helps us identify the major contributors to pollution at different stages, providing a scientific basis for policymakers to target key emission sources," said Li Yunting, technical director at the center.
Coordinated by the Beijing Municipal Ecology and Environment Bureau, the center has conducted four rounds of PM2.5 source analysis studies with other institutions, with results released in 2014, 2018, 2021 and 2025.
The latest analysis showed that regional transport contributed 57 percent of Beijing's PM2.5 pollution. Among local sources that accounted for the remaining 43 percent, vehicle emissions and residential sources represented the largest share of pollution, a distinctive characteristic of a major international metropolis.
The monitoring results have provided scientific support for a series of pollution-control measures. For example, Beijing has promoted new-energy vehicles to reduce transport emissions and adopted advanced techniques, including air-supported membrane structures, to control dust emissions. Meanwhile, coal combustion pollution, once a major contributor, has almost been eliminated and is no longer listed among the main sources, reflecting broader national efforts to reduce coal consumption, promote clean energy and upgrade heavily polluting industries.
With PM2.5 concentrations now at relatively low levels, further gains in air quality will depend on more targeted, science-driven approaches.

SMARTER ENVIRONMENTAL GOVERNANCE
Beyond monitoring pollution, Beijing has built a data-driven environmental governance system that links monitoring, regulation and enforcement in a closed loop from detection to action and follow-up evaluation.
Developed by the center and known as the innovative regulation-monitoring-inspection linkage model, the system integrates artificial intelligence, the Internet of Things, satellite remote sensing and vehicle-mounted monitoring technologies to pull together environmental data from multiple sources onto a unified platform.
"The system brings information that was once scattered across different departments onto a single platform," said Zhang Likun, director of the smart system division at the center, adding that this enables off-site enforcement and joint cross-sector actions involving housing, water resources and transportation, significantly improving the efficiency and precision of environmental management.
Using more than 30 intelligent algorithms, the platform automatically analyzes data and identifies potential pollution risks, based on which monitoring staff identify the most pressing problems and forward them to enforcement departments.
The approach has already drawn international attention. Clean Air Asia, an international nongovernmental organization focused on improving air quality across Asia, featured the system as a representative case study in its "China Air 2025" report. The model was also presented at the 2026 Better Air Quality Conference and recognized with the Certificate for Clean Air Best Practice Sharing.
China has integrated ecological conservation into its modernization drive. As the country speeds up efforts under the Beautiful China Initiative, Beijing's experience demonstrates how technology can support more precise, coordinated and sustainable environmental governance.

二 | 中国女单选手占据四强,最终王曼昱和王艺迪在分别淘汰陈梦和孙颖莎后进入了决赛这场中国选手的“内战”中。比赛一开始,双方就展开激烈对攻,王曼昱先声夺人,以11比9和11比4先赢两局。第三局,王艺迪以11比9扳回一局。

三 | 接下来的比赛双方战况胶着,王曼昱以11比7赢下第四局后,王艺迪在第五局同样以11比7还以颜色。第六局,王曼昱稳扎稳打,以11比7锁定整场比赛的胜利。“心态上比较坚决果断,技战术方面处理得不错是赢球的关键,这次在布达佩斯比赛对自己的锻炼非常大,收获很多。”王曼昱赛后表示。男单决赛则更具戏剧性。林高远是唯一进入四强的中国选手,比赛伊始林高远火力全开,以11比3、11比7和14比12连下三城。

四 | 但随后他却突然“哑火”,以两个6比11被对手连追两局。第六局,林高远更是在手握六个赛点的情况下,以11比13遭到逆转。关键的决胜局,林高远率先达到9分,而后又出现心态变化,最终以9比11输掉整场比赛。
