A System Dynamics Approach for Developing Zone Water Demand Forecasting: A Case Study of Linkong Area

System dynamics (SD) approach for developing zone water demand forecasting was developed based on the analysis of its water resources system which has multi-feedback and nonlinear interactions amongst system elements. As an example, Tianjin Binhai Linkong water resource system dynamic (SD) model was set up according its dual water supply feasibility and necessary and different quality water demand for different department utility characters to forecast different water resources demand of the planning years, in which population, economy, and environment factors was considered into one package. Furthermore, through comparing and analyzing the simulation results in different development mode which the article framed, the article got the forecasting results of the water resources demand of Linkong in sustainable use of water resources strategy, thus afforded scientific support to sound plan.
