| 摘 要： | 当前,应急响应范式已经由“预测-应对”转变为“情景-应对”,应急地图作为应急测绘地理信息保障服务的重要内容,其制图方式也应该有所改变。本文介绍了突发事件情景及地理场景的定义,指出地理场景是各情景要素存在或发生的物理空间,同时也是应急地图表达的对象;论述了应急场景快速制图的基本原理及该制图模式具有的4个主要特点;将传统的地图信息传输理论与新应急响应范式相结合,提出了应急场景快速制图模式下的地图信息传输模型,详细论述了模型中空间信息的传输过程,并分析了该过程中影响信息传输效率的地图发送端和接收端的空间认知。

| Abstract: | At present, the emergency response mode has been changed from "prediction-response" to "scenario-response". Emergency thematic map as an important content of emergency surveying and mapping, its production way should be changed according to the new mode. This paper introduces the definition of unconventional emergency scenarios and geographic scenarios, points out that geographic scenarios as the physical space in which various scenario elements exist or occur are the object of emergency mapping, discusses the principle and 4 main characteristics of rapid mapping of emergency scenario, proposes a cartographic information transmission model combining the traditional cartographic information transmission theory with the new emergency response mode, gives detailed explanations to the process of spatial information transmission and analyzes the spatial cognition of map senders and receivers which affects the efficiency of cartographic information transmission. |

| Keywords: | unconventional emergencies emergency scenario rapid mapping information transmission model spatial cognition |
