海洋是地球生态系统的重要组成,是海洋生物赖以生存的繁殖地和栖息地,温度、pH以及盐度是海洋生态系统的重要环境限制因子。工业革命以来,由于二氧化碳(CO2)过量排放引起的全球性气温升高,直接导致了海水温度和表层CO2分压(pCO2)的急剧升高,改变了海水pH以及盐度的动态平衡,不同程度地影响了全球海洋生态系统原有的稳定性和生物多样性,对近岸海洋渔业发展以及海洋生态资源的可持续利用也产生诸多不利影响。本文从全球变暖引起的海水温度、海水pH以及海水盐度变化三个方面,综述了海洋生物在生长、发育、繁殖以及种群迁徙等方面对海洋环境限制因子变化的响应。
Oceans are playing a critical role in ecological equilibrium. As one of important components of natural ecosystem, oceans provide habitat and breeding places for marine organisms. Sea water temperature,pH and salinity are three key limiting factors of marine environment, which can affect many processes of marine organisms, such as growth, development, breeding, population migrations and so on. With the increasing emission of anthropogenic carbon dioxide (CO2), the dynamic balance of marine limiting factors is changing gradually which can influence the stability and biodiversity of marine ecosystem,as well as the sustainable development of marine fishery. In this paper,we reviewed the response of marine organisms to the alternations on seawater temperature,pH and salinity causing by CO2- driven global warming.
