GIS技术支持的地表水资源管理信息系统数据库设计

Design of the Database for Surface Water Resource Management Information System Based on GIS

水资源数据涉及的因素众多并且复杂,因此,数据库在建设过程中必须严格按照相关的规范和标准进行,从而为系统的调用打下坚实的基础。本文以GIS技术支持的地表水资源管理信息系统数据库建设为例,对数据库的建设进行了系统论述,其中主要包括:标准化数据编码与数据管理、数据分类与编码、数据分析和数据库建立的步骤等。这将为类似研究提供一定的借鉴作用。

The complexity of water resources data demands a design of database strictly according to related regulations and standards, which is to lay a solid foundation for the system. By taking the database construction of surface water resources management information system as an example, the paper discusses the construction of the database system, including standardized data coding and data management, data classification and coding, data analysis and database creation step, etc. This will provide a reference for similar studies.
