Abstract A disaster risk index and vulnerability index evaluation model ,a red tide disaster risk evaluation index system ,is established by theory of red tide disaster risk as one of the main marine disasters in Chi‐na ,by entropy method and analytic hierarchy process (AHP) and by red tide disaster data in Liaoning coastal cities in the past 70 years to determine the index weight ,and to make disaster risk classification . The risk assessment results revealed that Dalian was within a high level of risk ;Dandong ,Yingkou and Huludao were found in the medium level of risk ,while Panjin and Jinzhou belong to the low level of risk . The evaluation results are primarily consistent with red tide disasters statistics data in past ten years ,indi‐cating that this method is significance for red tide disaster risk definition and prevention in Liaoning coastal cities .
