摘　　要：多元异构的灾害灾情数据是各种灾害信息系统的基础和核心,科学高效的管理和应用这些数据尤为重要。介绍了基于Oracle Spatial的技术设计与构建多元灾害信息数据库的结构框架,分析了存储数据信息的种类、属性及特点,研究了数据的存储方式。在多元异构数据统一管理的基础上,初步实现了多元灾害信息的存储、查询、绘图及显示等功能。It is very important that multi-resources and heterogeneous disaster information data can be managed and applied scientifically, because it is the foundation and the core of disaster information management system. This paper introduces the structure of multi-resources disaster information database which is designed and constructed by Oracle Spatial, and analyzes the category and attribute of data which is storied by the database and researches the method for storing spatial data. Application program, which can be used to query, draw and analyze multi-resources disaster information data, is developed by integrative management of multi-resources and heterogeneous disaster information data.
