| Summary: | High-risk societies are uncertain, ambiguous and unpredictable. Risk fluctuations are prone to the intertwining and overlapping of various accident hazards and safety risks. China is prone to the interweaving and overlapping of various accident hazards and safety risks, which leads to an increase in the number of factors affecting public safety as well [1]. Therefore, this paper will quantify specific ranking indicators in terms of frequency of hazards, degree of hazards and vulnerability to different hazards. The ranking is based on the quantified results in red, yellow and green and the hazard risk level is calculated according to the risk formula. This study will take the Chengdu-Chongqing region as an example and optimise the storage of materials in the emergency logistics base in order to maximise the precise and rapid supply of materials to the main demand points. The efficiency of emergency material deployment will be further improved and emergency materials will be well secured.
