The Infrastructure of the Grounderwater Resources and Environment Information System of Southwest Karst Area

结合国内水资源与环境管理信息系统的前沿及面临的问题,着重从系统目的分析、结构设计和功能实现三个方面来论述西南岩溶地区水资源信息系统的构建。系统数据库由空间数据库和属性数据库两大部分组成。系统的功能主要包括:数据更新修订功能、信息资料查询功能、空间分析功能和绘图打印功能。

The infrastructure of the grounderwater resources and environment information system of southwest Karst area is introduced. The aim is to analysis the spatial distribution of the groundwater resources, environment, geological calamity and hydraulic engineering by means of the database and spatial analysis method in GIS. The systemic database is made up of spatial database and attribute database. The functions of the grounderwater resources and environment information system of southwest IKarst area can be divided into four parts： datum updating, information querying,spatial analysis and ploting.
