[目的/意义] 通过引入结构化图标来改善以往应急地图中的图标表征，旨在协调更为复杂的危机信息交互与协作。[方法/过程] 设计适用于危机情境下的结构化图标，并以此为基础设计基于结构化图标的可视化交互与协作模式。[结果/结论] 首先，结构化图标的先设基底图标可以显化危机事件关联，改善信息搜索交互体验；其次，结构化图标可以动态表征危机信息的时空属性，增强信息认知，提升决策者协同决策能力。理论上，提出一种基于结构化图标的应急信息交互模式，丰富应急信息可视化理论和应急交互理论。实践上，优化基于图标的应急协同系统的设计，增强参与者与应急信息的互动，有助于决策者进行高效及时的应急协同决策。
[Purpose/significance] This study aims to coordinate more complex crisis information interaction and collaboration by introducing structured icons to improve icon representation on previous emergency maps.[Method/process] This study designed the structured icon for crisis situations. Then a visual interaction and collaboration model based on the structured icon was designed.[Result/conclusion] Firstly, the pre-icon of structured icon can show the relationship of crisis events and improve the interactive experience of information search. Then, structured icon can dynamically represent the temporal and spatial attributes of crisis information, enhance information cognition and enhance decision makers' collaborative decision-making ability. In theory, this paper proposes an emergency information interaction model based on structured icon. It enriches the theory of emergency information visualization and emergency interaction. In practice, the research optimizes the design of icon-based emergency coordination system. It enhances interaction between participants and emergency information and helps decision makers to make accurate and timely decisions in collaboration.
