在全面考虑城市再生水供水量影响因素的基础上,基于系统动力学的原理和方法,构建了再生水供水量预测模型,并运用VENXIM软件进行仿真模拟,最后以华北某市中心城区作为对象进行实例研究。结果表明,系统动力学方法不仅能够全面考虑再生水供水量的各主要影响因素,而且能够将各因素间的相互作用关系有机的统一到一个模型中去;模型的系统性强,预测精度高。 Based on the comprehensive consideration of the influencing factors of urban reclaimed water supply, based on the principles and methods of system dynamics, the water supply forecasting model for reclaimed water was constructed and simulated by VENXIM software. Finally, a case study was conducted in a downtown area of ​​North China . The results show that the system dynamics method can not only fully consider the main factors affecting the water supply of reclaimed water, but also unify the interaction among various factors into one model. The system is strong and the prediction accuracy is high.
