In 2020,the sudden arrival of COVID-19 brought great harm to people’s lives and economic and social development,and also posed challenges to the emergency management capacity of governments at all levels.Public health emergencies once again attracted the attention of the whole society.The grass-roots level is the main battlefield to maintain public security,and the grass-roots government is the most important behavior subject to deal with the crisis.How to optimize the emergency management mechanism to achieve effective prevention in advance,quick handling in the event,and proper recovery after the event is the current practical problem that needs to be solved by the grass-roots government.In this paper,Public health emergencies are regarded as life with the stages of occurrence,development and extinction,using the three-phase model of life cycle theory,the Guanshanhu District COVID-19 in epidemic prevention and control process is divided into three stages,deeply analyze the practice,effectiveness,existing problems and reasons of each stage,According to the problems presented in each stage,the optimization strategies and measures of emergency management mechanism are put forward.Through research and analysis,you can see that the epidemic prevention and control work in Guanshanhu District has achieved remarkable results,took the lead in realizing zero cases in the whole province,GDP to achieve positive growth,and higher than the average level in the province,these results have inseparable from the Guanshanhu Government the fastest,most closely,the most effective prevention and control measures.But in the prevention and control work still exposed prevention and control efficiency is not high,precision is not enough.In view of these deficiencies,this paper gives suggestions on establishing and improving mechanisms of monitoring and early warning,joint prevention and control,etc.In particular,it makes in-depth exploration on the integration mechanism of big data and crisis management.It is hoped that this paper can provide reference for policy makers and other local governments in public crisis management,and for future theoretical research and emergency management model innovation. |
