摘要:: 阐述了基于天地图的地震灾情综合研判系统建设目的、系统设计以及系统功能实现,并将该系统应用于2017年九寨沟7.0级地震。结果表明:该系统实现了灾区基础背景信息与快速评估结果的查询和可视化,多源灾情信息汇聚,灾区范围、次生灾害、交通震害等主题综合研判,以及研判成果产出等功能,为开展灾情协同综合研判提供了便捷的工具,为震后地震应急指挥决策提供了重要灾情信息支持,有效支撑了地震应急工作。

Abstract:: We described the purpose,system design,design and system function realization of the earthquake disaster comprehensive evaluation system based on “Tianditu”,and applied this system to the Jiuzhaigou M_S7.0 earthquake. The results show that the system realizes the functions as follow:the query and visualization of basic background information and rapid assessment results,the convergence of multi-source disaster information,the comprehensive evaluation of disaster areas,secondary disasters and traffic earthquake hazards etc.,as well as report productions and outputs. It provides a convenient tool for experts to carry out coordinated earthquake disaster comprehensive evaluation,important disaster information support for post-earthquake emergency command and decision-making,and effectively supports earthquake emergency work.
