Simulation of Urban Ecological Water Demand Using Multi-objective System Dynamic Model

Jing Du, Ling Xu, Shuo Wang, and Fenglin Yang

Abstract—Water crisis has become the critical point in limiting cities’ economical and social development nowadays. With the sharply increasing conflict of supply and demand of water resources, the prediction of ecological water demand is becoming an important part in urban water resource management. Thus, based on the overview of theories and methods for the calculation of urban ecological water demand, this paper introduces a multi-objective system dynamic model which combines system dynamic model with multi-ecosystem theory to simulate urban ecological water demand, with Dalian City, China as a case study. It is demonstrated that the proposed model can be an applicable and flexible method and it also provides an alternative approach for sustainable urban water utilization which can reconcile the conflict between urbanization process and water resource restraints.
