摘要
为了保护辽河河口湿地现有资源、实现对湿地生态环境的修复,集成河口湿地相关数据设计并构建湿地管理信息系统数据库是十分必要的。结合湿地数据的特点,分析了GIS数据库的主要实现方案,确定了基于扩展对象关系型数据库管理系统的辽河河口湿地数据库的设计方案。针对系统所要实现的不同专题功能,对数据需求、数据组织方式、表结构设计进行了分析,通过PostgreSQL/PostGIS实现了辽河河口湿地空间数据与属性数据的统一存储。
In order to protect the exiting resources in Liaohe estuary wetland and achieve restoration of ecological environment,it is necessary to design and build database composed of related data for estuary wetland management information system.Combined with data features in the wetland,this paper analyzed those schemes in which GIS database were implemented and made a choice to design the database based on extended Object Relational Database Management System.According to special functions to be realized in the system,this paper studied on data requirement、organizational manner and logical structure of tables.At last,special data and attribute data were successfully stored together in PostgreSQL/PostGIS.
