Deep Dive: Atmospheric Composition Evolution
Representative Research
The research on "Evolution Patterns and Regulatory Principles of Key Atmospheric Components under Climate Change" led by Peking University's College of Environmental Sciences and Engineering is representative and was selected as one of China's Top Ten Environmental Technology Advances in 20246 .
This research addresses the dramatic changes in atmospheric composition caused by human activities, particularly organic aerosols, ozone and other key secondary pollutants generated by thousands of organic molecules through atmospheric multiphase physical and chemical processes6 .
These components not only harm human and ecological health but also affect radiation balance and convective conditions, thereby influencing the potential and stability of renewable energy resources6 .
Research Methods & Process
The project team adopted a multi-method integrated research strategy:
- Long-term field observations: Establishing observation stations in different regions to continuously collect atmospheric composition data
- Emission inventory construction: Systematically organizing emission data from various pollution sources to form a complete emission database
- Atmospheric chemistry model development: Establishing high-precision models to simulate atmospheric composition changes based on physical and chemical principles
- Meteorology-chemistry online coupling: Closely integrating meteorological processes with chemical processes to build comprehensive assessment models
Key Findings & Significance
Through the above methods, the research team significantly improved the simulation accuracy of atmospheric chemistry models for atmospheric oxidation and secondary pollutants6 .
They clarified the long-term evolution characteristics and driving factors of atmospheric organic aerosols and ozone in China, revealed the synergistic benefits of pollution reduction under meteorological-chemical bidirectional feedback, and then proposed a feasible framework for secondary pollution control6 .
This research is important for improving pollution prevention capabilities, protecting public health, and advancing the dual carbon goals6 .
The results directly serve China's key atmospheric pollution prevention regions such as the Chengdu Plain area's "Sky-Land Integrated Atmospheric Traceability Prevention and Control Platform," providing technological support for atmospheric pollution prevention and control in major cities such as Deyang and Mianyang, and have achieved remarkable results6 .
The Scientist's Toolbox

New National System for Environmental Governance
China is actively exploring a new national system for technological research in the ecological and environmental field. This system, targeting the characteristics of the social-economic-environmental complex giant system, has constructed a "1+X" DSE (Decision-Support-Execution) system architecture and organization method4 .
This system, through the construction of a multi-level three-dimensional "1+X" organizational model in practice in the Beijing-Tianjin-Hebei region, Yangtze River Basin, and Yellow River Basin, achieved "large corps coordinated combat-style" technological research4 .
It broke down the organizational, regional, informational, technological, and disciplinary barriers that previously existed in major research activities, promoted technological collaborative innovation, and formed a closely embedded regional ecological environment collaborative governance system for scientific research4 .
Future Outlook & Path Implementation
Monitoring Systems
The realization of China's ecological and environmental technology development roadmap to 2050 requires the comprehensive development of multidisciplinary high technology, especially innovation in ecological and environmental monitoring platforms and system theory3 .
Data Integration
Data integration and system simulation will also play a key role, by establishing a national ecological and environmental three-dimensional monitoring-data integration-system simulation trinity experimental center to support scientific decision-making3 .
International Cooperation
In addition, international cooperation is indispensable, cooperating with neighboring countries to establish a Global Change Asian Center to jointly address global ecological and environmental challenges3 .
These measures will together constitute the guarantee system for the implementation of the roadmap, ensuring the smooth realization of China's ecological and environmental technology development goals.
Globally, climate change mitigation and adaptation have become the focus of Earth system science, and the relationship between ecosystems and human well-being has become the main object of international ecological research3 .
The ecological and environmental technology development roadmap formulated by China is not only related to the country's own sustainable development but also an important contribution to global environmental governance.
It demonstrates a major country's rational thinking and long-term planning in the face of ecological challenges.
When we look toward 2050, this road may be full of challenges, but at least we already have a blueprint to guide the direction.
