The comprehensive risk assessment of COVID-19 is a key approach to the comprehensive epidemic risk management while the assessment method is the key to the epidemic risk assessment. This paper uses the public security "triangular model" and considers the three factors, i.e., the incident(the hazard of the virus itself), the vulnerability of hazard-affected carriers(the vulnerability of vulnerable groups), and the effectiveness of emergency management to establish a multidimensional risk assessment method, which can help to provide effective method for the next epidemic response and plans of resource allocation. According to the assessment results, the top five provinces with highest comprehensive risk are respectively Hubei, Shanghai, Hong Kong, Beijing and Guangdong. Within Hubei province, the top four cities are Wuhan, E'zhou, Xiaogan and Huanggang.
