摘　　要：沉积物-水界面是水环境中水相和沉积物相之间的转换区,对水环境中物质的循环、转移、贮存有重要的作用。本文总结了国内外的主要研究成果,概述了沉积物-水界面营养盐交换研究的时空分布情况;分析了营养盐交换通量的研究方法、沉积物-水界面营养盐的迁移转化过程、沉积物中营养盐的赋存形态及累积规律和沉积物-水界面营养物质的生态效应等方面的研究进展和发展趋势。对在这一领域的进一步研究具有参考意义。The sediment-water interface is a transition zone between the water and sediment phase in the aquatic environment. It plays an important role in circulation, transfer and storage of chemical species in the aquatic environment. In the paper, the results from many studies around the world in spatial and temporal distribution of nutrients in water and sediments were summarized. The discusses of the methods of nutrient fluxes from the sediments to the overlying water,the process of diffusion and transfer of nutrients at the sediment - water interface,the mechanisms governing the nutrient chemical speeiation and accumulation in the sediment and the ecological impact of nutrients on the sediment - water interface were done also. It has reference value for further research in this field.
