在全球气候变化和人类活动的双重影响下,海洋浮游植物乃至整个生态系统的结构已发生明显的变化(如生态系统转型).综述了在全球气候变化背景下,海洋浮游植物生物量及群落结构的变动趋势,探讨了浮游植物群落结构演变与厄尔尼诺-南方涛动(ENSO),太平洋年代际涛动(PDO)和北大西洋涛动(NAO)等现象的关联,分析了群落结构与生物泵效率的耦合关系.
Under the global climate changes and human activity stress,marine phytoplankton as well as ecosystem has been observed signal of change(e.g.regime shift).The paper reviewed the variations of phytoplankton biomass and community structure under global climate changes,and the correlation between community structure and El Nio-Southern Oscillation(ENSO),Pacific Decadal Oscillation(PDO) and North Atlantic Oscillation(NAO).This paper finally discussed the coupling between phytoplankton community structure and biological pump and POC flux in the ocean.
