中文摘要：
对20多年来国际上关于沉积物中有机氮的研究做了综述和回顾。氮是重要的生源要素，是水环境中动植物新陈代谢不可或缺的元素之一，但过量易于造成生态环境巨大破坏，沉积物中有机氮与水体的交换可能会成为水体元素的“汇”和“源”。研究有机氮在沉积物水界面迁移转化过程是研究水环境的基础和关键，对氮元素的生态系统中的环境化学研究有十分重要的意义。
英文摘要：
A review with 41 references is given on the progresses of around the world within 20 years. Nitrogen is essential for all of the the concentration of nitrogen in aquatic environments is in low level, studies on organic nitrogen in sediment living organisms on the earth. Although nitrogen content could inhibit the growth of phytoplankton and survival of zooplankton whereas the high level it could result in large scales of awful problems faced by human beings. The interactions of overlying waters via organic nitrogen could be very important for understanding the nitrogen cycles in aqueous systems of the source and the reservoir. Therefore, it＇s very interesting and crucial for geochemists, environmental scientists to investigate the organic nitrogen in sediments, especially in the most abundant surface sediments.
