摘要

Exploring rumor dissemination model of public emergencies and its prevention and control strategies under the individual psychological effects has great theoretical and practical significance. Considering the individual psychological effects in the process of rumor spreading, a nonlinear spreading strength function is defined, and a rumor dissemination model affected by psychological effects is constructed, then verifying its effective application through stability analysis and numerical simulation. Results show that the spread of rumors presents different evolutionary trends based on different threshold characteristics, adjusting the parameters can make the rumors gradually disappear; the spread rate of rumors significantly affects the final quantitative changes of various groups of people; individual psychological effects affect the trend of the spreading strength of rumors, thereby changing the disseminator quantity.
