Abstract
With the continuous improvement of marine strategic status, the degree of emphasis on marine environmental security incidents has increased. In order to effectively prevent and manage marine environmental events, we need to work through risk assessments to prevent the occurrence of events or reduce the impact of events. Based on the theory of public safety triangle, this paper studies and analyzes the comprehensive risk assessment of marine environmental safety. Based on the historical disaster situation investigation and the existing disaster risk assessment research results, a comprehensive risk assessment framework was established. According to the development process of the marine environmental safety incident and the influence of the incident, the comprehensive risk evaluation index system is constructed from three aspects: event risk, disaster tolerance and emergency management. According to the expert experience and judgment matrix, considering the acceptable level of risk, the risk assessment grading standard is established, which provides theoretical support for the comprehensive risk assessment of marine environmental safety.
Highlights
The issue of environmental safety has become an associated issue that cannot be ignored in the process of industrialization
China has a vast sea area, and a large number of marine environmental safety incidents have emerged, which seriously affect the sustainability of marine development and utilization, and it is an important aspect of national security
Historical case data based on typical marine environmental security incidents such as storm surge, Brassica mosses, red tides, and oil spills, the actual business needs for risk prevention and control, and the development process of the marine environmental safety event chain, from the hazards of the incident, the vulnerability of the disaster-bearing entity and the emergency Three aspects of the distribution of rescue capabilities are used to screen indicators for marine environmental safety risk assessment
Summary
The issue of environmental safety has become an associated issue that cannot be ignored in the process of industrialization. Comprehensive risk assessment of environmental safety is increasingly becoming an important area of risk assessment research. With the introduction of the “One Belt, One Road” policy, the marine development process has been accelerating. China has a vast sea area, and a large number of marine environmental safety incidents have emerged, which seriously affect the sustainability of marine development and utilization, and it is an important aspect of national security. Taking integrated risk assessment as an entry point, analyzing the distribution and weaknesses of the marine environment security situation, and realizing the targeted enhancement of marine environmental safety incidents, is of great significance for effective protection of the marine environment
