Focusing on emergency broadcasting scenarios during sudden incidents, this study adopts a core perspective of spatial analysis and real-time visualization technologies within Geographic Information Science (GIS). By examining case studies of emergency broadcasts for disasters such as earthquakes and floods, it systematically analyzes the application forms of GIS technology in presenting emergency information, as well as the strategies hosts employ to convey spatial information and its value in decision support.Based on crisis communication theory and spatial information cognition theory, this study examines the relationship between anchors'"spatial information interpretation capabilities"and"risk warning accuracy" versus public risk avoidance decision-making efficiency and societal panic mitigation effectiveness through case comparisons and simulation experiments. It reveals issues such as the fragmentation and lag risk warning accuracy"of anchors with the efficiency of public risk avoidance decisions and the effectiveness of alleviating social panic. This study reveals issues such as the fragmentation and lag in spatial information transmission during current emergency broadcasts, proposing a collaborative emergency communication pathway of "technical support - anchor delivery - public response." This framework provides theoretical support for enhancing the professionalism and practicality of emergency broadcasting.
