Multi-scenarios Simulation and Analysis of Wildfire Information Dissemination Through Different Media

Abstract

The increasing frequency of wildfires poses a significant threat to populations worldwide, underscoring the importance of understanding the dissemination of early warning information through various communication channels in diverse wildfire scenarios. This study focuses on provinces with high wildfire risks and establishes four typical information dissemination models: Short Messaging Service (SMS), Television (TV), online social networks (NET), and offline disaster information officers (DIO). The dissemination of early warning information through these four channels under multiple wildfire scenarios are simulated, including daytime and nighttime information releases, and analyzes their characteristics. The findings reveal that SMS exhibits the fastest dissemination speed and reaches the largest number of recipients. Television is demonstrated to have extensive coverage capabilities in areas with complex terrain, while online social networks show efficient dissemination in urban areas and regions with robust network coverage. The comprehensive analysis of these four information dissemination channels under various wildfire scenarios is crucial for formulating effective emergency response and disaster mitigation strategies.
