基于Geodatabase的滑坡地质灾害数据库设计

滑坡地质灾害数据库建设在减灾工作中占有重要地位。本文首先对思茅区滑坡地质灾害资料分析和整理，然后从数据库的概念设计、逻辑结构设计和数据库建设方面详细讨论了滑坡地质灾害数据库的设计。在概念设计阶段对滑坡属性表的基本E-R图进行设计；逻辑设计中对滑坡地质灾害信息编码，属性数据库逻辑结构和空间数据库的结构以及数据完整性设计进行详细讨论。论文最后在详细介绍了空间数据库存储方案的基础上讨论了空间数据库和属性数据库的建立方法。

The Design of Landslides Geological Hazards Database Based on Geodatabase

The construction of landslides geologic hazards database is very important for the hazards prevention and treatment. In the first part, the paper analyzes and sorts the landslides geologic hazards data of Simao district, and then discus the design of database from the conceptual design, logical structure design and database construction aspect in detail. The conceptual design mainly introduces the design of basic entity-relational (E-R) diagram of landslides attributes table. The process of database logical structure design mainly includes the code of landslides geological hazard database, the design of attribute database and spatial database logical structure and the design of data integrity. In the end, the paper introduces the methodologies of spatial database storage at first, and then discusses how to construct the spatial and attribute database in detail.
