Abstract: Public policy is an important tool for ecological environment governance.Through the analysis of the policy text,it is possible to grasp the general laws of the ecological environment governance process and discover the prominent problems in the process of policy operation.The air pollution control of Fenwei (Fenhe River and Weihe River in Shanxi Province) Plain has become the main battlefield of national air pollution prevention and control.Based on the research method of grounded theory,this paper analyzes the policy text of Fenwei Plain atmospheric governance,and establishes a theoretical model of policy process including policy belief,policy interaction,policy feedback and policy improvement.The results show that there are some practical problems in the process of policy operation,such as weak awareness of policy concepts,insufficient operability and coordination of policy texts,relatively single channel for policy feedback,and negative and passive policy improvement.Therefore,it is necessary to strengthen the sense of responsibility and synergy,pay attention to the coordination and cooperation in the process of policy interaction,constantly improve and optimize the bottom-up dynamic tracking feedback mechanism and the long-term mechanism of policy improvement,and finally achieve the continuous improvement of the policy effectiveness of the cross-administrative region ecological environment synergy governance.
