This has led to the development of a new paradox that has subverted traditional media. Focusing on magnification has a real impact on society. In particular, the ecological environment concerns the well-being of the people and the international image. With the rapid development of the economy and society, environmental protection issues have become increasingly prominent and have attracted the attention of all sectors of society. The new media public opinion field has naturally developed into the center of environmental impact exchange and fermentation, and public public opinion crisis often comes along. The public opinion risk points of ecological and environmental protection problems are difficult to control, the public opinion ecology is varied, and the public opinion crisis lurks in every corner where public discourse is expressed. Obviously, how to do public public opinion management in the era of new media prevailing, scientifically controlling the risk of public opinion, effectively coping with the crisis of public opinion, scientific policy and promoting environmental co-governance have become a long-term, major and urgent task for the government and the environmental protection department.

Finally, the system explores the common public opinion management measures of the public security department, especially from the internal mechanism and external influence factors such as the manifestation, formation cause and process law of the public opinion crisis, and proposes a relatively perfect management response strategy and mechanism, and comprehensive legal system. Various factors such as government guidance, online media behavior, public obligations, and cooperation and communication between the parties are explored, and how the government should create a scientific and effective response strategy in the process of creating a good public opinion environment for environmental protection work in the new media era.
