Development of the 'Capital Water Resources Allocation Decision Supporting System' for the city of Beijing

摘要

The problem of water scarcity has been a main restricting factor for many large cities. How to realize the sustainable utilization of water resources through modern technologies has become an important research subject for the development of big cities. Water resource problems in Beijing are composed of water shortage, the outstanding conflict between water supply and demand, In this paper the approach of an decision support system (DSS) for the joint optimal operation of different water sources such as surface water, ground water, recycled water and transferred water is presented. This decision support system will be developed in the frame of the joint Chinese-German project "Toward Water-Scarcity Megalopolis's Sustainable Water Management System". It is of significance for the sustainable development of economics and society in Beijing and the success of the Olympic Games in 2008. An indispensable requirement for such a DSS is a simulation model of the water resources and the water supply system. The simulation model for the region Beijing and the first results are presented here.
