以三峡库区流域为对象，利用ArcGIS Engine组件库，以VB为程序开发语言，以DLL动态连接库的形式构建了水力/水质模型库，以Geodatabase为数据库，开发了一体化的水污染综合管理信息系统，为三峡库区突发性水污染事故的应急管理提供了一种信息化的技术手段。该系统同时集成了多种数学模型，并实现了不同模型之间的无缝衔接，不仅具备了污染源动态管理、水体水质查询及评价、流速场和浓度场模拟等功能，而且具备了流域内突发性污染事故的应急管理功能。通过针对翻船事故污染的应急管理应用，表明该系统能快速模拟出事故污染带的迁移转化过程，自动统计出各种污染事故所产生污染带在不同时间的影响范围和污染程度，为突发性污染事故的应急措施提供决策支持。

An integrated water pollution management system for the Three Gorges Reservior Area (TGRA) titled as WPMIS_ER_TGRA was developed as an informationbased techenical tool for emergency response on water pollutant accident.ArcGIS Engine, a Geographic Information System (GIS) Module Warehouse, was used as programme developing platform, and Visual Basic (VB) as programming language.The mathematical models for hydraulic and water quality simulation were developed and integrated in the system and programmed as a DLL file via VB.WPMIS_ER_TGRA owns a new function of emergency lightening at watershed scale as well as the normal water environmental information management functions.The system was applied for emergency water pollution management by a dummy ship capsizal in Yangtze River.It was found that WPMIS_ER_TGRA could model the transfer and diffusion of the accident pollutants in rivers, quickly forecast the pollution situation and identify the influencing area and their changing with time in a few minutes just after the accident happened.
