近岸和河口低氧成因及其影响的研究进展

Research progress on cause of hypoxia and its influence in coastal and estuary region

近岸和河口区的富营养化加剧、赤潮频发和全球变暖是导致低氧加剧的主要原因。频繁发生的低氧事件和不断扩大的低氧范围对海洋生物个体甚至整个生态系统造成了严重的损害。文章结合近几年的研究报道,综述了近岸和河口低氧的形成原因,以及生物在分子水平、生化水平、个体水平以及生态系统水平上对低氧环境的响应。

The hypoxia is aggravated by the increasing eutrophication, the frequent algal blooms and global warming in coastal and es- tuary regions. The frequent hypoxia incidents and the expanding of its distribution have seriously damaged to the ocean organisms, e- ven the whole ecosystem. Combined with the related reports, the reviews on the cause of hypoxia in coastal and estuary regions and its influence on the environment at the molecular level and the ecosystem level were made.
