摘要
海洋硫循环是全球硫循环重要的组成部分,而活跃于上层海洋的二甲基硫(DMS)是主要的生源硫化物,是现今国内外硫循环研究的热点之一。二甲基硫的生物、化学过程较为复杂,其在水体中的分布与浮游植物、浮游动物、细菌等生物因素以及光照、营养盐等环境因素密切相关。本文综述了与DMS循环有关的生物、化学循环过程及其参数化方案,包括细菌消耗、光化学氧化和海-气交换等。根据国内外研究进展,讨论了需要解决的问题,建立了东中国海DMS循环的概念模型。期望通过发展一个中国东部陆架海域物理-生物地球化学耦合三维生态动力学模式,获取DMS海气交换通量的时空分布,并定量评估中国东部陆架海域对全球大气温室效应的贡献。
The marine sulfur cycle plays an important role in the global sulfur cycle.Dimethylsulfide(DMS)has been identified as the major volatile sulfur compound,which is active in the upper ocean,becoming one of hotspots of the sulfur cycle research all over the world.Because of its complex biological process and chemical process,the distribution of DMS in the ocean is strongly related to biological factors including phytoplankton,zooplankton,bacterium and environmental factors including light,nutrient and etc.The DMS processes including bacterial DMS degradation,photochemical oxidation,air-sea exchange and related parameterization schemes are reviewed in this paper.We develop a three-dimensional hydrodynamic module coupled biophysical and geochemical process of DMS in the East China Sea.Based on the model,the spatial and temporal distribution and air-sea flux of DMS will be discussed,then the contribution of DMS released from the East China Sea to the global warm will be qualitative assessed.
