海洋沉积物中氮的生物地球化学过程

摘要

主要阐述海洋沉积物中氮的存在形式与分布、氮的早期成岩和去营养化作用、硝化和反硝化作用以及氮与生物特定种群的关系等,探讨了影响海洋沉积物中的氮循环的主要因素,分析了海洋沉积物中的氮与生态系的关系,以期对研究氮的海洋生物地球化学过程有所帮助.%Mainly reviewed distribution of organic nitrogen, early diagenesis (such as counteract-eutrophication, nitrification/ denitrification et al.), the controlling factors of nitrogen cycling; and the relationship between nitrogen and ecological system in sediments in recent years, which may contribute to research the nitrogen marine biogeochemical process.
