气候变化对近岸海域缺氧的影响机制研究进展

Study advance on influence mechanism of climate change on coastal hypoxia

随着全球变暖的不断加剧,近岸海域缺氧对气候变化的响应已成为近年来国内外研究的热点问题。本文综述了气候变化对近岸海域缺氧的影响机制研究进展,气候变化将通过径流量及营养盐输入、风应力和水体温度的变化等方面影响缺氧的形成和发展。指出今后应结合多种技术手段,开展气候改变径流量和风对缺氧影响的研究,并就缺氧对生物代谢变化的响应,以及缺氧对气候变化的滞后效应及相关过程的识别等方面进行深入研究。

As the global climate is getting warmer in the last decades, the response in the coastal hypoxia to the climate change has become a hot spot. In this paper, the author reviews the mechanism of climate change exerted on the coastal hypoxia. The formation and development of hypoxia would be significantly affected by the climate-induced variations in river discharge or precipitation, nutrient flux, wind stress and water temperature in the coastal zones. It~ essential to combine all methods, research the impacts of changes in discharge and wind on hypoxia, as well as the response of hypoxia, and understand the ecosystem metabolism due to the climate variation. Furthermore, the identification of delayed effects and all possible mechanisms of the climate change on hypoxia should be carried out.
