河口及近岸海域底边界层生物地球化学过程研究进展

Advances in biogeochemical process in benthic boundary layer of estuarine and coastal area

河口及近岸海域底边界层的生物地球化学过程在很大程度上影响着陆源物质的迁移转化及向海洋的输送通量,是陆海相互作用研究、海洋碳的"源、汇"研究以及氮、磷循环研究的关键。本文对河口及近岸海域底边界层生物地球化学过程研究进展进行了综述,重点介绍了底边界层中移动泥的特点和功能及微生物在其生物地球化学过程中的作用,并对今后的研究进行了展望。

The biogeochemical processes of benthic boundary layer in large river estuary and coastal area impact the transport and transformation of terrestrial materials and their seaward flux.It is the key problems of studies of land-ocean interaction,carbon sources and sinks in oceans and the nitrogen and phosphorus cycle.The advances and future outlook in research on biogeochemical process in benthic boundary layer of estuary and its adjacent sea area were analyzed and summarized with highlighting the features and functions of mobile muds in benthic boundary layer and the role of microorganisms in the biogeochemical processes therein.
