氮磷营养盐控制与湖泊蓝藻水华治理研究进展

Research Progress in the Control of Nitrogen and Phosphorus Nutrients and the Management of Cyanobacterial Bloom in Lakes

湖泊富营养化与蓝藻水华对国内的湖泊生态系统造成了严重的危害。通过氮(N)、磷(P)营养盐控制来实现湖泊蓝藻水华的治理已成为当前湖沼学研究中的焦点。目前的研究中对不同的氮磷营养盐污染,蓝藻水华与营养盐之间的关系以及通过不同调控氮磷的方法来实现蓝藻水华的控制有较多争议。文中分析了当前富营养化湖泊中氮、磷营养盐的来源,诱导蓝藻水华的发生机制以及通过氮磷营养盐控制来实现蓝藻水华治理的研究进展。通过综合湖泊富营养化控制的理论研究与藻类水华治理的实践技术,为富营养化湖泊中蓝藻水华治理的研究提供理论基础和实践指导。

The eutrophication and cyanobacterial blooms had been a serious problem to aquatic ecosystem in Chinese Lakes. Many limnological researches for the control of cyanobacterial blooms focus on the control of nitrogen(N),phosphorus(P)in lakes. However,there are many controversies in recently researches,such as the pollution of nitrogen and phosphorus,the relationships between cyanobacterial blooms and nutrients,and the different ways for regulating nitrogen and phosphorus. In this paper,the different source of nitrogen and phosphorus in eutrophic lakes,the bloom-forming mechanism caused by the increase of nutrients and the managements for regulating nitrogen and phosphorus which result in the control of cyanobacteria blooms were analyzed.Among these methods,the principle and the application cases of eutrophication and algal blooms were discussed to provide theoretical suggestions and practical guidance for the control of cyanobacteria blooms in eutrophic lakes.
