全球气候变化导致区域和全球范围内的海洋氧气大量流失.海洋缺氧会影响生物的形态、新陈代谢和适应能力等，并导致生物迁移甚至死亡.此外，缺氧还会影响生物种群的数量、组成和分布，进而破坏海洋生态系统的功能.探究区域和全球海洋的生物数量和生物多样性如何响应气候变化背景下的海洋缺氧问题，可以为维持海洋生态系统的稳定性提供理论基础.
Global climate change has led to a large amount of oxygen loss in regional and global ocean. Deoxygenation can result in biological migration and death by affecting morphology, metabolism, adaptability, etc. In addition, deoxygenation can also damage the stability of ecosystem by changing community quantity, composition, and distribution. Understanding the response of regional and global biomass and biodiversity to ocean deoxygenation can provide a theoretical basis for a sustainable management of marine ecosystem.
