Abstract: Dimethylsulfide is the major sulfur compound emitted from sea, which is mainly produced from marine phytoplankton. This article reviews the basic process of production and decomposition of dimethylsulfide in marine euphotic zone, including assimilatory sulfate reduction, production, accumulation and release of dimethylsulfoniopropionate as well as production and consumption of dimethylsulfide.

Key words: dimethylsulfide, dimethylsulfoniopropionate, marine, phytoplankton

摘要： 二甲基硫是海洋排放到大气中的主要含硫化合物。海洋二甲基硫主要来源于浮游植物。论述了海洋中二甲基硫产生和降解的基本过程，包括同化硫酸盐还原、二甲基硫前体——二甲基磺基丙酯的生成、积累和释放、二甲基硫的产生及其在海水中的命运等。
