【摘要】：地震已成为威胁人类生命、财产和社会经济发展最严重的自然灾害之一。针对当前地震应急减灾系统灾害信息获取时效性差、自动化和定量化程度低及信息集成共享等方面的不足,通过收集、整理地震灾害时空信息,结合灾区基础地理、多源遥感卫星影像及动态灾情信息,利用面向对象及主题的数据模型设计在线的地震应急减灾时空一体化数据库;提出了构建基于WEBGIS和空间技术的地震减灾信息化平台的总体设计架构、技术体系及功能模块;开发了平台原型系统,初步形成了地震灾害动态监测、灾害评估、灾情信息实时共享以及应急减灾辅助决策的一体化产品,为提高我国地震灾害应急减灾水平提供了借鉴作用。
[Abstract]:Earthquake has become one of the most serious natural disasters that threaten human life, property and social economic development. In view of the shortcomings of the current earthquake emergency and disaster reduction system, such as poor availability of disaster information, low degree of automation and quantification, and information integration and sharing, through collecting and sorting out the space-time information of earthquake disaster, combining with the basic geography of the disaster area, Multi-source remote sensing satellite images and dynamic disaster information are used to design an online spatio-temporal integrated database for earthquake emergency and disaster reduction using object-oriented and thematic data models. The overall design framework, technical system and function module of the information platform for earthquake disaster reduction based on WEBGIS and space technology are put forward, the prototype system of the platform is developed, and the dynamic monitoring and evaluation of earthquake disaster are preliminarily formed. The integrated product of real-time sharing of disaster information and auxiliary decision-making of emergency disaster reduction provides a reference for improving the level of earthquake disaster emergency mitigation in China.
