With the rapid development of social economy and the acceleration of urbanization, the problem of environmental pollution has become increasingly prominent, especially the air quality problem has become one of the important factors restricting human health and sustainable development. However, with the joint efforts of the government, enterprises and the public, China has made remarkable achievements in air pollution control in recent years, and the environmental quality in many areas has been significantly improved.

First, pay equal attention to policy guidance and technical support

At the national level, a series of policies and measures aimed at improving the quality of the atmospheric environment have been issued, such as the Three-Year Action Plan to Win the Blue Sky Defence War, which provides guidelines for local governments to formulate specific implementation plans. At the same time, support for the development of clean energy, new energy vehicles and other industries has been increased, and scientific research institutions have been encouraged to develop advanced pollutant emission control technologies, which has promoted the optimization and upgrading of industrial structure and technological progress.

Second, multi-agent participation forms a joint force

In addition to government departments, more and more enterprises have begun to take the initiative to assume social responsibilities and reduce exhaust emissions by improving production technology and strengthening internal management. The general public has gradually realized the importance of protecting the environment and actively participated in energy conservation and emission reduction activities to jointly safeguard a good ecological environment. This diversified cooperation model has effectively improved the attention and support of the whole society for air pollution prevention and control.

Third, the monitoring system is improved to help accurate policy.

A nationwide air quality monitoring network has been established, and the concentration information of major pollutants such as PM2.5 and ozone can be released in real time, which not only reflects the changing trend of environmental conditions in various regions in time, but also provides an important basis for scientific decision-making. In addition, with the help of big data analysis, key pollution sources and their contribution rates can be identified more accurately, so as to take more targeted measures for remediation.

Fourth, international exchanges promote experience sharing

Faced with global warming and trans-border pollution, China actively participates in international cooperation in related fields and shares successful experiences and advanced practices with other countries and regions. This not only helps to improve the level of self-governance, but also contributes to the construction of a fair, reasonable and win-win world environmental protection pattern.

To sum up, the theme of "air pollution phenomenon and positive environmental protection problem reduction" fully reflects China's unremitting efforts and significant progress in coping with the challenges of air pollution in recent years. In the future, we have reason to believe that with the joint efforts of all citizens, China's sky will be bluer and brighter!
