乌梁素海环境与资源地理信息系统空间数据库设计

THE DESIGN OF SPACE DATABASE OF THE GIS OF WULIANGSUHAI ENVIRONMENT AND RESOURCES

运用数据库技术与地理信息系统技术,通过分析乌梁素海的历史监测数据,应用Superm ap2003地理信息系统软件作为建立数据库的操作平台,通过对基础资料的矢量化,将所得的综合点、线文件进行编辑,误差校正后,分层形成图形文件,将图形文件与属性文件相联接,再通过投影转换和数据格式转换,形成乌梁素海环境与资源地理信息系统空间数据库,从而为今后的空间分析和多用途的开发应用提供了重要的基础数据资料。

By using the database and GIS technology, and analying the history supervise data, and taking the Supermap 2003 software of GIS as the operating platform, inputting the basic vector data, editing the graphic elements（ dots, lines, ets. ）, correcting errors, constructing graphic layers and connecting the attribute to graphs, then converting projection and format, the space database of the GIS of Wuliangsuhai wetland environment and resources was formed. It provides an important basis for further special analysis and multi - purpose development and application.
