(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.
。在特别的游戏演示室里，我们看到了Geforce RTX 2060笔记本，一款全新的G-Sync显示产品，以及一款65英寸的Omen Eperium 65 bfgd显示屏，即将出售。G-SYNC重新进化G-SYNC和Geforce图形卡无疑是完美的匹配。在新闻发布会上，英伟达将G-Sync细分为三个级别，最低级别为无G-Sync，其次为G-Sync兼容，最高级别为G-Sync终极。G-Sync兼容并不意味着它必须为G-Sync技术而构建，但在Nvidia的实际测试中，它仍然能与G-Sync显示出良好的兼容性，这意味着它可以在不付出太多成本的情况下实现与G-Sync显示类似的性能。在超过400个可变刷新率监视器的实际测试中，只有12个监视器符合G-SYNC兼容标准，NVIDA慷慨地给出了推荐购买列表供玩家参考。顾名思义，G-Sync Ultimate是下一段时间内G-Sync的最高标准。

三 | 它将代表所有高端显示技术的集合，例如需要支持HDR 10、高可变刷新率、超低响应时间、配备G-Sync芯片等。

四 | 英维达还展示了一些尴尬的只支持自由同步显示在游戏过程中，如闪光屏幕，绘画撕裂等。

五 | 似乎在N卡前面的自由同步的强制打开没有太多好的水果吃。当然，英伟达对朋友的支持也不缺，比如35英寸的罗格-斯威夫特PG35VQ将被出售。

六 | 它不仅支持G-SYNC 3440 x 1440，而且刷新率为200赫兹。价格似乎不便宜。更便宜的是即将推出的bfgd 65英寸显示器omen eperium 65，最大4K 144Hz加上G同步和屏蔽功能。

七 | 毫无疑问，惠普甚至减轻了显示器的重量，使其在正式量产之前更容易搬运和挂在墙上。同时，这种显示器在国外的价格接近5000美元，足以让我们买一台高端4K电视机。Geforce RTX 2060笔记本到Geforce RTX 2060图形卡以及Geforce RTX 2080、RTX 2070笔记本也在现场展出。

八 | 在Geforce RTX 2060的测试中，我们发现Geforce RTX 2060的性能与Geforce GTX 1070 Ti相当，但DLSS和RTX使其更具吸引力。现场演示也是如此。通过游戏优化和DLSS合作，Geforce RTX2060可以在保证高质量的前提下轻松实现光线跟踪效果和高帧数，这也使得视频卡本身具有成本效益。RTX笔记本可能是游戏笔记本玩家最容易达到高潮的产品。现场显示笔记本电脑包括Microstar GS65、Lenovo Y740、Razer Blade 15、Alienware M15、Rog Zephrus S GX531、Acer Preditor Triton均使用Geforce RTX 2080 Max-Q图形卡，而HP Omen、Giga Aero 15和Microstar GS75则使用Geforce RTX 2070 Max-Q玩游戏。

九 | 演示、流利、管理得当就足够了。关键是Geforce RTX系列图形卡笔记本电脑也更容易获得完整的游戏体验。毕竟，你不需要额外的G-SYNC显示器，笔记本电脑制造商也不会通过成本控制夸大他们的价格。可以肯定的是，2019年的钱包生活注定是艰难的。无论是Geforce RTX笔记本电脑、G-Sync显示器还是台式电脑，都有很多花钱的理由，而且这些产品中的许多很快将在第一季度上市销售。似乎如果没有2019年的Computex，今年的PC升级预算将耗尽。
