中文摘要：
磷是国民经济发展必须的重要矿产资源，由于其难以再生的特点，它的消耗将造成严重的资源流失，各种含磷产品的消费对水体等自然环境也会产生巨大影响。本文以科学发展观为指导，贯彻循环经济理念，从磷矿资源产业全生命周期出发，运用灰色系统方法建立其动态模型，在此基础上对现状发展趋势及各项循环经济策略实施效果进行定量描述和情景分析，考察磷资源的利用和环境影响状况，比较优劣，得到结论以指导实践，具有重要意义。
英文摘要：
Phosphorus is an important mineral resource for China. Since it is very difficult to recycle, the consumption of phosphorite will cause the irreversible losing of limited mineral resources, and the generation and use of many kinds of phosphors products also gen- erates severe environment problems. Based on the principles and methods of chemical englneering, and circular economy, the dynamic model of Chinese phosphorus industry is built by applying the gray system theory. The present status and the results of executing the circular economy schemes on the system are dynamically simulated and quantificationally studied, Finally, the results of dynamic seenario simulations are summarized to draw the conclusion and guide the practice.
