There is a large amount of probability information in risk management. Promoting the public's understanding of probability information is one of the important challenges in risk communication. From the perspective of information expression, review the research of domestic and foreign scholars on risk probability information communication, and conduct evidence integration of risk probability information communication strategies for the public based on the evidence-based system evaluation method. After systematic search and strict screening, a total of 57 included articles were obtained. The topic synthesis method was used to extract information and topic refining of the included literature, and 11 three-level descriptive topics were identified. After induction, five second-level analytical topics and two first-level analytical topics were embedded. The study found that public-oriented risk probability information communication strategies include: communication strategies in the expression of risk probability information, such as presenting accurate digital probabilities, and flexible use of visual aids; communication strategies in the content of risk probability information presentation, such as using clues Improve the evaluability of information, increase the individual relevance of probability information, and select the profit and loss reference point for reporting probability. At the same time, it should be noted that factors such as trust level, cognitive ability, time pressure, and information limitations will also affect the role of risk probability information communication strategies.
