摘要
根据国家环保总局的要求,笔者以国家测绘局编制的1:25万覆盖安徽全境的数字地图作为空间数据,以水环境功能区划登记表作为属性数据,开发了安徽省水环境功能区划的GIS。介绍了用工作站版Arc/Info7.1和ArcView3.2软件来实现安徽水环境功能区划工作过程。
Required by the State Environmental Protection Bureau, we have developed the geographic information system of water environmental function blocks of Anhui Province with 1:250000 digital map compiled by the State Bureau of Surveying and Mapping as spatial data, and water environmental function block registration table as attribute data. This paper describes the process to realize the division of water environmental function blocks of Anhui Province by use of the workstation version Arc/Info 7.1 and software ArcView3.2.
