地球已进入以人类为中心的“人类纪元”。为使全球可持续发展,应考虑今后几十代人对磷资源的需求。介绍了世界磷资源现况及国内外最新磷矿储量数据,分析了我国磷肥产品结构;提出高品位、易加工磷资源用于磷化工、磷化学品合成,低品位、难选磷矿用于含磷肥料生产的新思路,并认为生产过磷酸钙、钙镁磷肥比生产磷铵类肥料对磷资源利用更合理。提出了磷肥产业结构调整新战略,以使我国磷资源的可采寿命从目前的100~200年延长至500年。
The Earth has entered a human-centric “human era.” For sustainable global development, the need for phosphorus resources for decades to come should be considered. The present status of the world’s phosphorus resources and the latest phosphate rock reserves at home and abroad are introduced, and the structure of phosphate fertilizer products in China is analyzed. High-grade and easily-processed phosphorus resources are proposed for phosphorus chemical and phosphorus chemical synthesis, low-grade and refractory phosphate rock Phosphorus fertilizer production of new ideas, and that the production of superphosphate, calcium magnesium phosphate than the production of ammonium phosphate fertilizer on phosphorus utilization more reasonable. Put forward a new strategy of phosphate fertilizer industrial restructuring in order to make the recoverable life of China’s phosphorus resources from the current 100-200 years to 500 years.
