With the rapid development of China's economy, especially theimplementation of the "Ocean Power" strategy, the number of ships hasincreased rapidly, and the trend of high-speed and large-sized ships isincreasingly evident. The risk assessment of port waters is of greatsignificance to the safety of ship navigation, and can provide referencevalue for the supervision of Maritime department. In order to evaluatethe risk status of different port waters objectively and quantitatively,and to determine its risk level, based on entropy weight method andmatter-element theory, the risk evaluation model of entropy weightmatter-element is established, which overcomes the subjectivity anduncertainty of weight distribution of each risk evaluation index. As anexample, the entropy matter-element model is used to evaluate thewater traffic safety risk in three port waters, the Binzhou port,Dongying port and Weifang port, synthetically considering the naturalenvironment, traffic environment, port condition and security conditionof the three ports. In order to test the objective and quantitativeevaluation results, 30 maritime experts have been invited to score therisk degree of the port according to their own experience. The results ofqualitative and quantitative evaluation are compared to verify theaccuracy and reliability of the evaluation model.
