With the rapid development of economy and the acceleration of urbanization, air quality has increasingly become the focus of attention from all walks of life. In recent years, the Chinese government and all walks of life have attached great importance to the prevention and control of air pollution, adopted a series of effective measures and achieved remarkable results. The purpose of this paper is to explore the effects of these measures and show the environmental protection achievements in air control.

I. Policy Support and Improvement of Laws and Regulations

Since the State Council issued the Air Pollution Prevention Action Plan in 2013, the state has successively issued a series of relevant policy documents, such as the Three-year Action Plan to Win the Blue Sky Defence War, which has defined specific objectives and tasks. At the same time, constantly strengthen the construction of environmental protection laws and regulations system, increase the illegal cost, and provide a solid legal guarantee for improving air quality.

Second, technological innovation promotes industrial upgrading

Scientific and technological innovation is the key to solving environmental problems. Many areas have effectively reduced pollutant emissions by promoting the use of clean energy, developing new energy vehicles and implementing comprehensive treatment of industrial pollution sources. For example, in Beijing, by vigorously promoting the "coal to electricity" and "coal to gas" projects, the increase in PM2.5 concentration caused by coal burning in winter has been greatly reduced; In Shanghai, the popularization and application of vehicle exhaust purification technology and electric vehicles have been promoted, which has promoted the green transformation in the transportation field.

Third, public participation strengthens the power of social co-governance

In addition to the efforts of the government, the broad masses of the people also actively participate in environmental protection actions. Through various forms of publicity and education activities, the whole people's understanding of the importance of air pollution prevention and control has been improved. All localities also organized volunteer teams to participate in activities such as planting trees and cleaning homes, which formed a good atmosphere for the whole society to care for and support ecological environmental protection.

Fourth, establish and improve the monitoring system

In order to grasp the air quality more scientifically and accurately, a number of high-level automatic monitoring stations of atmospheric environmental quality have been built nationwide. This not only helps to find and solve problems in time, but also provides data support for formulating more accurate and effective prevention and control strategies.

　　After years of unremitting efforts, China has made remarkable achievements in air control. But we should also be soberly aware that the prevention and control of air pollution is a long-term and arduous task, which requires our continuous efforts. In the future, we expect more innovative solutions to be put forward and put into practice to make our sky bluer and our breath fresher.
