鄱阳湖流域湿地管理信息系统的开发与应用

Development and Application of Wetland Management Information System of Poyang Lake Watershed,China

针对鄱阳湖流域湿地的多样性和时空复杂性的特点,采用先进的大型关系数据库Oracle9i和空间数据库引擎ArcSDE9建立包含DLG、DOM、DEM和专题数据的多尺度无缝空间数据库,并在ArcEngine组件库的基础上开发了基于C/S模式的鄱阳湖流域湿地管理信息系统。

For the complexity of the environment system, the database technology is very suitable to handle mass data concerning various parameters of environment. The common database could only manage the attribute data. The database incorporating Geography Information System （GIS） could be more effective to solve the problem. The advanced large-scale Relational Database Management System （RDBMS） Oracle9i and spatial database engine ArcSDE9 are employed to establish seamless GeoDatabase of Poyang Lake Watershed, Digital Line Graph （DLG）, Digital Ortho Map （DOM）, Digital Elevation Model （DEM） of various scale, other thematic and statistical data are collected. Meanwhile, the client system ＂Poyang Lake Watershed Management Information System＂ is developed based on ArcEngine COM library. This system could provide the powerful support for the Poyang Lake Watershed management and the decision-making.
