基于GIS的预警信息“一张图”平台设计与实践

Design and Practice of Early Warning Information"One Map"Platform Based on GIS

内蒙古自治区自然灾害频发、多发,防灾减灾形势异常严峻,建立高效的突发事件预警信息发布体系,对于自治区突发事件应急保障极为重要。本文探讨了基于GIS的预警信息一张图的建设思路与方法,基于GIS技术进行预警信息资源整合,建立预警信息全要素“一张图”,并利用WebGIS空间分析技术实现风险分析与研判,为预警信息的精准靶向发布提供支撑。最后提出了该平台建设的总体架构、功能设计与关键技术,并总结了平台近年来的应用成效,为自然灾害防灾减灾与应急辅助决策支撑体系的建立提供借鉴。

Natural disasters occurred frequently and frequently in Inner Mongolia Autonomous Region,and the situation of disaster prevention and reduction is extremely severe.It is very important to establish an efficient early warning information release system for emergency response in Inner Mongolia Autonomous Region.This paper discussed the construction ideas and methods of one map of early warning information based on GIS technology,integrates early warning information resources based on GIS technology,establishes"one map"of all elements of early warning information,and uses WebGIS spatial analysis technology to realize risk analysis and judgment,so as to provide support for accurate targeted release of early warning information.This paper puts forward the overall architecture,functional design and key technologies of the platform construction,and summarizes the application effect of the platform in recent years,so as to provide application reference for the establishment of natural disaster prevention and mitigation and emergency decision support system.
