With the development of social economy and the improvement of people's living standards, environmental problems have attracted increasing attention from all walks of life. Among them, air pollution, as the most extensive and harmful environmental pollution problem, has become one of the key factors restricting China's sustainable development. However, with the joint efforts of the government and all walks of life, the vision of "air pollution is great and environmental problems are few" is gradually becoming a reality.

I. Policy Guidance and Legal Construction

In recent years, the China Municipal Government has issued a series of laws, regulations and policy measures for the prevention and control of air pollution. The Air Pollution Prevention and Control Action Plan (referred to as "Atmosphere Ten" for short) released in 2013 is the first document at the national level to comprehensively and systematically deploy air pollution prevention and control work, and has set clear objectives, tasks and specific implementation paths for all regions of the country. Since then, guidance documents such as "Three-year Action Plan to Win the Blue Sky Defence War" have been issued one after another, further strengthening the comprehensive control of air pollution in key areas and key areas.

Second, technological progress promotes industrial upgrading

Under the guidance and support of policies, industries such as clean energy and new energy vehicles have developed rapidly, and traditional industries with high energy consumption are also accelerating their transformation. For example, the power industry has greatly reduced the emissions of pollutants such as sulfur dioxide and nitrogen oxides by promoting ultra-low emission technology and upgrading high-efficiency coal-fired generating units; In the field of transportation, the pace of R&D and application of electric vehicles and hydrogen fuel cell vehicles has been accelerated, effectively reducing vehicle exhaust emissions.

Third, the awareness of public participation has increased.

With the in-depth development of environmental protection knowledge popularization education activities and the effective play of the role of media public opinion supervision, more and more people began to pay attention to and participate in air quality protection actions. Whether it is to reduce the use of disposable plastic products, choose public transportation, or participate in various green volunteer service projects, every small move is an important step towards a cleaner and healthier living environment.

Fourth, improve the monitoring and early warning system

In order to grasp the changing trend of air quality more scientifically and accurately, and take timely countermeasures, a relatively complete environmental quality monitoring network and heavy pollution weather forecasting and early warning mechanism have been established throughout the country. These measures not only improve the decision-making efficiency and service level of government departments, but also provide important information reference for ordinary people.

To sum up, behind the "great phenomenon of air governance", it is inseparable from the strong top-level design at the national level, the support of scientific and technological innovation, the efforts of the whole society and the sound and effective supervision mechanism. In the future, we have reason to believe that with continuous efforts, the sky in China will be bluer and bluer, and the air will be more fresh and pleasant.
