With the acceleration of society, industrialization and urbanization, the problem of air pollution has become increasingly serious, which has become one of the major bottlenecks restricting the sustainable development of China's economy and society. In order to effectively meet this challenge, the state has issued a series of policies and measures aimed at improving air quality and protecting the ecological environment. Among them, the Environmental Protection System of Air Purification Rules, as a guiding document, has played an important role in promoting environmental governance.

　　. Background analysis

In recent years, due to the great increase of fossil energy consumption such as coal and the sharp increase of vehicle exhaust emissions, many areas in China, especially big cities, frequently encounter smog weather, which seriously affects people's quality of life and health. Facing the grim situation, the government attaches great importance to it and promotes the prevention and control of air pollution to the national strategic level to do a good job.

　　Second, the main content

1. Strengthen source control: implement stricter emission standards for key industries and limit the approval of high-pollution projects; Promote the proportion of clean energy use and reduce the dependence on coal burning.

2. Strengthen supervision and law enforcement: establish and improve a nationwide monitoring network system to improve data transparency; Increase illegal costs and severely investigate and deal with excessive sewage discharge.

3. Promote public participation: enhance citizens' awareness of environmental protection through media publicity and encourage all sectors of society to actively participate in emission reduction actions; Establish a reward mechanism for reporting and stimulate people's enthusiasm for supervision.

4. Promote technological innovation: support scientific research institutions to tackle key technical problems and accelerate the transformation of scientific and technological achievements into practical applications; Support the development of green and low-carbon industries.

Third, the prospect of results

Since the implementation of the system, all parts of the country have actively responded to the call and taken effective measures to implement various tasks and objectives. According to statistics, in the past few years, the concentration of major pollutants has dropped significantly, and the number of excellent days has continued to increase. Beautiful scenes such as "Beijing Blue" and "Shanghai Green" have gradually become the norm. However, we should also be soberly aware that long-term unremitting efforts are still needed to achieve comprehensive and lasting air freshness.

In short, the Environmental Protection System of Air Purification Rules provides a solid guarantee for China to win the blue sky defense war. In the future, we expect more efficient and feasible new policies and methods to emerge, and jointly protect this blue sky so that future generations can breathe fresher air and enjoy a healthy and happy life.
