摘　　要：利用组件MapObjects开发汉江水污染控制信息系统,在系统的数据库设计中,采用了异构数据模型,这种数据的组织方式,很符合所研究流域信息管理的特点,更能发挥汉江流域水环境专题GIS管理流域水环境信息的优势。该系统综合运用计算机信息技术,实现了汉江流域的水环境信息的集中、高效管理,以及流域水污染的预测、评价。为及时制定汉江流域的水污染预防和控制策略提供参考信息。The control information system for Hanjiang River water pollution was developed using MapObjects technology. The isomerous data model was used in the design of GIS database, which was in conformity with characteristics of the valley and was fitter to managing the information. The system realizes an efficient and concentrated management of water pollution information, and can forecast and evaluate the valley's water pollution by making integrative use of computer information technology, which can provide information for setting down strategies of water pollution prevention and control.
