With the rapid development of social economy and the acceleration of urbanization, the problem of environmental pollution has become increasingly prominent, among which air pollution has become one of the important factors restricting the sustainable development of economy and society. In recent years, with the guidance of national policies and the joint efforts of all sectors of society, China's air quality improvement has achieved remarkable results, and environmental protection work has achieved fruitful results.

First, policy guidance, effective governance measures

Since the State Council issued and implemented the Action Plan for Air Pollution Prevention and Control in 2013, the whole country has responded positively. Various provinces and cities have successively issued a series of concrete and feasible air pollution prevention and control schemes, and strengthened the control of pollution emissions from key industries. Through the implementation of clean energy substitution, strengthening the rectification of industrial pollution sources, optimizing traffic structure and other measures, the concentration of major pollutants such as PM2.5 has been effectively reduced, and the overall air quality level has been improved.

Second, scientific and technological innovation to promote green transformation

Science and technology is the key supporting force to solve environmental problems. In recent years, China has continuously increased investment in environmental protection technology research and development, supported enterprises to carry out cleaner production technology transformation and upgrading, encouraged the development of new energy automobile industry, and promoted the use of energy-saving products and services. These measures not only promoted the adjustment of industrial structure and technological progress, but also laid a solid foundation for achieving a win-win situation for economic development and environmental protection.

Third, public participation to build a beautiful home

A good ecological environment is the most beneficial to people's livelihood. In order to let more people participate in environmental protection actions, local governments have actively built platforms to mobilize all sectors of society to pay attention to and support ecological construction. By holding various publicity activities and voluntary service activities, citizens' awareness of environmental protection has been improved, and people's enthusiasm and initiative in caring for nature and protecting the environment have been stimulated.

To sum up, through unremitting efforts, China has made some achievements in air purification, but we must also clearly realize that the current situation is still severe and complicated. In the future, we need to continue to deepen institutional reform and improve the system of laws and regulations; Further increase capital investment and enhance the ability of scientific and technological innovation; Strengthen publicity and education, create a good atmosphere for the participation of the whole people, and leave a beautiful home with sky blue, green land and clear water for future generations with more firm determination and practical actions.
