英文摘要：

After the Middle Route of South-to-North Water Diversion Project has been constructed, a complex w ater supply sys-tem w ill be formed in Beijing. In this paper, the real-time w ater quantity dispatching system of Beijing was developed based on J2EE layered architecture to adapt to the new water supply syst em. In view of the actual water quantity dispatching, the design concept and key technology of real-time w ater quantity dispatching system, and the packaging of hydrodynamic model interface were described. The realization scheme of real-time w ater quantity dispatching syst em based on GIS platform and Flash were displayed. The system is technologically advanced, practical and reliable, and user-friendly. It combines t he geographic informa-tion system, calculation, display, and query as a whole, w hich can provide effective technical support for real-time w ater quant ity dispatching.
