摘要
全球变暖会导致海水变暖和海水酸化,进而威胁海洋生态系统的稳定性及生物多样性.本文以海水变暖和海水酸化为视角,分析全球变暖对海洋生态系统的影响.研究表明,海水变暖会影响海洋动物体内的生物酶,进而影响海洋动物的新陈代谢;海水变暖会导致海平面高度增加,对沿海的河口、滩涂、红树林等生态系统造成破坏;海水变暖会导致南极和北极冰山融化,破坏极地海洋生态系统.海水酸化会影响钙化动物的钙化进程,影响新陈代谢和繁殖等功能,对海洋中钙化生物的生存造成严重威胁;海水酸化还会影响海洋浮游植物的光合作用,从而降低海洋的初级生产力.
Abstract
Global warming can lead to warming and acidification of seawater,thereby threatening the stability and biodiversity of marine ecosystems.From the perspective of seawater warming and acidification,this paper analyzes the impact of global warming on marine ecosystems.Research has shown that seawater warming can affect the biological enzymes in marine animals,thereby affecting their metabolism;seawater warming will lead to the increase of sea level height,and damage the coastal estuaries,mudflat,mangroves and other ecosystems;seawater warming can lead to the melting of icebergs in Antarctica and Arctic,damaging polar marine ecosystems.Seawater acidification can affect the calcification process of calcified animals,affecting their metabolism and reproductive functions,posing a serious threat to the survival of calcified organisms in the ocean;seawater acidification can also affect the photosynthesis of marine phytoplankton,thereby reducing the primary productivity of the ocean.
