(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 |     【环球时报报道 记者 梁睿 马俊 李煜】进入8月以来，解放军接连与多国举行双边演习，包括中国和白俄罗斯的“神鹰-2026”空降兵联合训练、中国和泰国的“鹰击-2026”空军联合训练、中国和埃及的“文明之鹰-2026”空军联合训练以及中国和阿联酋的“猎鹰盾牌-2026”空军联合训练。

三 | 多名中国军事专家接受《环球时报》记者采访时表示，这些演习不但能从各个维度提升解放军的实战能力，同时也展现中国作为负责任大国的军事担当，为世界和平贡献正义力量。        展现跨洲际投送能力     北京时间8月21日凌晨，参加中埃“文明之鹰-2026”空军联合训练的中国空军多型战机和参训官兵，跨洲际抵达埃及空军某基地。中国空军派出了歼击机、加油机、特种机、直升机等多型多架战机成体系参训。据介绍，转场途中，加油机既承担空中加油任务，也是空中指挥节点。在飞往埃及的途中，中国空军运油-20飞机为歼-16战机实施空中加油。

四 |     军事专家宋忠平告诉《环球时报》记者，今年是中埃两国空军第二次开展联合训练，去年参演的中国空军主力战斗机是歼-10C，今年派出歼-16，说明中国空军正有计划地让不同型号的主力战机走出国门。歼-16属于重型多用途战斗机，相比以制空为主的歼-10C，它的参训意味着双方可以进一步丰富联训的课目。    据央视报道，这次中国空军编队跨越6000多公里、飞行近9小时抵达埃及，途中由运油-20为歼-16战斗机实施多轮空中加油。

五 | 这不仅检验了歼-16自身的远程续航能力，也考验了运油-20的保障能力——两款机型通过实际拉练形成海外协同保障，本身就具有实战意义。对歼-16来说，这次远距离飞行是一次难得的考验，为后续更远距离的部署积累了宝贵经验。

六 |     宋忠平还认为，连续两年以体系力量赴非洲参训，说明中国空军的跨洲际演训正从能力验证走向常态化。未来中国空军需要更频繁地走出国门，与更多友好国家加强交流。埃及空军有独到的作战经验，该国地处热带，中国空军在陌生空域的演练也有助于积累不同气候环境下的战斗经验。    近期演训各有侧重     在此之前，中国和白俄罗斯的“神鹰-2026”空降兵联合训练已经于8月12日正式开始，计划持续至8月24日。

七 | 中国军事专家王亚男对《环球时报》记者表示，这次演习以联合城镇反恐行动为课题，主要开展侦察与反侦察、夺控与防卫、清剿与固守等演练，旨在提高联合反恐行动能力。白俄罗斯方面可能沿用苏军时期的做法，主打低空小规模伞降技术。王亚男认为，此次联训并非单向的学习借鉴，更多的是双方在反恐领域建立合作基础、熟悉彼此行动习惯的过程。

八 |         中泰“鹰击-2026”空军联合训练于8月20日在泰国空军乌隆基地圆满结束。

九 | 此次中泰联演，中方派出了歼击机、歼轰机、预警机、加油机等多型战机及地导装备参训，视频中可见中方运-20、歼-10C、歼-10S，泰方则有“鹰狮”和“阿尔法”等机型。    王亚男表示，从参演机型来看，歼-10C是中国空军主力装备之一，此次再度走出国门，体现其成熟可靠的实战能力；运-20承担大型运输任务，保障防空装备、航材和技术力量的远程投送。战斗机、预警机、加油机与大型运输机的组合，形成了一套完整的小规模远程部署和实战检验体系。

十 | 王亚男介绍说，在演练课目方面，联合防空在当前国际局势下具有现实意义。人道主义救援则是中国军队长期参与的常规课目，经验较为丰富。此次联演不仅检验了远程投送和部署能力，也体现了中泰两国在防务领域的务实合作。    此外，8月下旬至9月中旬，中国与阿联酋将在新疆和田举行中阿“猎鹰盾牌-2026”空军联合训练，两国空军将开展指挥推演、飞行训练、实兵混编演练等活动。此系中阿两国空军第四次举办该系列联训，旨在提升参训部队技战术水平，深化两军传统友谊与务实合作。

十一 |     为世界和平贡献正义力量     王亚男表示，解放军与外军联合演训的意义主要体现在两个层面：一是为未来可能的联合行动奠定基础——在反恐、重大国际安全议题上，彼此熟悉才能有效协作；二是联合演训本身有助于增强地区稳定，与友好国家在安全问题上达成一致，并常态化进行军事合作，对地区安全具有保障效应。

十二 | 总体而言，解放军正通过不断提升国际联合演训的水平，构建更加开放、灵活的军事合作格局。    对于解放军开始更多地走向海外参加联合演训，宋忠平认为，这代表中国空军的远程投送、空中加油和海外快速部署能力正在持续提升。同时，中国空军也在积累常规作战和非传统安全领域（如反恐、反海盗、人道主义救援、防灾减灾等）的多种能力。走出国门，既是为了维护自身发展利益，也是展现中国作为负责任大国的担当，为世界和平贡献正义力量。返回，查看更多。
