摘要
磷是造成水体富营养化的限制因子之一。在有效控制外源磷输入造成的污染时,沉积物中的内源磷成为污染主体,内源磷的释放对水体持续富营养化状态所产生的作用逐渐凸显。沉积物中内源磷的释放增大了湖泊、河流等生态系统的水体发生富营养化的风险,明晰沉积物中磷的迁移转化过程对改善水体富营养化现象具有重要意义。总结了沉积物和间隙水中磷的形态、分类以及测定方法,分析了磷在沉积物-水体系统中的迁移转化过程及其影响因素,论述了研究磷的生物地球化学循环对水环境修复的重要作用,并探讨了研究方向。
Phosphorus(P) is one of the limiting factors in water eutrophication. When the contamination caused by exogenous P input was controlled, the endogenous P in sediments became a source, and its release played an important role in water eutrophication. The endogenous P release in sediments would increase the risk of eutrophication in lakes, rivers and other aquatic ecosystems, and it is necessary to investigate the transportation and transformation of P in the sediments for improving water eutrophication. The forms, classification and determination methods of P in sediments and pore water were summarized, and the transportaion and transformation process of P in sediment-water system and its factors were analyzed. The importance of P′s biogeochemistry cycle for the rehabilitation of water environment was discussed, and future directions were pointed out.
