摘　　要：界定再生水的概念内涵,研究自来水和再生水的供给与需求,使用系统动力学方法建立水资源的供需流图以模拟现实的水循环以及再生水回用对水循环的影响。再生水回用使得水资源的使用方式由原来的"资源-产品-污染排放"的水资源单向流动方式,变成了"资源-产品-再生资源"的水资源循环流动的新模式。The concept of water recycle,supply demand of water and water recycle were studied in this paper.Water resources＇ supply and demand model was established with the systems dynamics method to simulate the water cycle and study the influence of recycle water.The use mode of water resources can transform from original water resources uniflow way-＂the resources-product-pollution＂ to new water resources recycle mode-＂the resources-product-regenerated resource＂ because of recycled water reuse.

关 键 词：再生水 系统动力学 供需 循环系统
