摘　　要：以南水北调中线工程水源区—丹江口水库和周围丹江支流淇河以及老鹳河的汇水区域为研究对象,利用已有水质监测数据,结合河流污染物混合衰减模型,采取点面、部分与整体相结合原则,以组件式GIS软件ArcEngine 9.3为开发平台,采用C#2008编程语言,以ACCESS2003为数据库,进行水环境容量计算,开发了水环境容量动态展示系统,实现了污染物不能降解、污染物浓度稳定、忽略纵向离散系数三种情况下的水环境容量计算及动态展示和空间、属性数据的显示、查询、保存及输出功能。Taking the catchment areas of the Danjiangkou reservoir and the surrounding tributary Qihe and Lao-guan rivers in the water source area of the Middle Route of the South-to-North Water Transfer Project as case study, water environment capacity of dynamic display system is developed, which uses the existing water quality monitoring data, combines with the river pollutant mixture damping model and adopts the principle of combination of points, parts and whole. The system uses the component GIS software Arc Engine 9.3 as the development platform, adopts the C#2008 programming language and uses ACCESS2003 as the database. It can perform water environment capacity calculations and dynamic display, query, save, and output of space and attribute data under conditions: pollutant cannot be degraded, pollutant concentration is stable, and vertical dispersion coefficient is ignored.
