摘　　要：针对高速铁路工程结构的复杂性、专业协同的系统性、运营安全的高可靠性特征,从高速铁路时空信息安全保障方面出发,以唯一时空基准为主线,将不同时空信息进行关联,形成高速铁路全域范围、全要素时空信息的高效组织模型,实现高速铁路各专业、各领域海量时空信息的有效组织;利用地理信息系统(GIS,Geographic Information System)可视化技术、空间分析技术和大数据实时动态渲染技术,实现高速铁路不同时空信息及其组织关系的实时动态可视化展示,为高速铁路运营安全态势的自主预测及预警提供辅助决策及空间信息技术支撑。In view of the complexity of high-speed railway engineering structure,the systematicness of professional collaboration and the high reliability of operation safety,this paper studied the spatial-temporal information data organization model with all elements in whole domain for high-speed railway from the aspect of high-speed railway spatial-temporal information security.Taking the unique spatial-temporal benchmark as the main line,the paper associated different spatial-temporal information to form an efficient organization model of high-speed railway spatial-temporal information with all elements in the whole domain,so as to implement the effective organization of massive spatial-temporal information in various specialties and fields of high-speed railway;By using GIS(Geographic Information System)visualization technology,spatial analysis technology and big data real-time dynamic rendering technology,it was realized the real-time dynamic visualization display of different spatial-temporal information and organization relationship of high-speed railway,which provided auxiliary decision-making and spatial information technology support for independent prediction and early warning of high-speed railway operation safety situation.
