Abstract
In order to effectively manage and control risks and improve the accuracy of urban safety risk assessment, a revised model of urban safety risk based on inherent risk screening is proposed, risk screening standards and industry risk coefficients for different industries are formulated, and a three-level urban safety risk assessment process is established, in which risk assessment subjects, industry management departments and governments (regions) are linked. Risk assessment is carried out through the bottom-up model of "point line surface", overlapping to form industrial and regional risks. Taking A district of a city in the south of China as a sample, the safety risk assessment of accident disaster cities is carried out in a "point line plane" mode. It is clear that the assessment object is the risk point hazard sources of production and business units and public safety areas under the jurisdiction. The results show that this method can systematically and comprehensively find out the key points of urban risk management and control, effectively evaluate the regional risk level, and provide decision-making basis for the hierarchical management and control of urban security risks.
