摘　　要：地球的生命支持系统依赖于生物地球化学循环,海洋在其中扮演着极其重要的角色。海洋浮游生物的代谢反应是碳、氮、铁等元素海洋生物地球化学循环的重要驱动力。揭示海洋浮游生物群落动态变化的调控机制及其如何响应环境变化,对于认识和预测全球变化下的海洋生产力以及元素生物地球化学循环的演变至关重要。基于“海洋痕量元素及同位素生物地球化学循环(GEOTRACES)”、Tara Oceans等研究计划的成功实施,近年来国际学界正在积极策划发起“全球变化下的海洋生物代谢与营养元素循环(BioGeoSCAPES)”研究计划,旨在从全球尺度上系统揭示并量化海洋浮游生物如何响应适应气候变化,阐明其与元素生物地球化学循环的互作关系。The Earths life support system relies on its biogeochemical cycles,with the ocean playing a pivotal role.The metabolic activities of marine plankton are key drivers of the marine biogeochemical cycles of elements such as carbon,nitrogen and iron.Understanding the regulatory mechanisms that govern dynamic changes in marine plankton communities and their responses to environmental shifts is critical for understanding and predicting changes in ocean productivity and elemental biogeochemical cycles under global climate change.Building on insights gained from international initiatives such as GEOTRACES(Marine Biogeochemical Cycles of Trace Elements and Isotopes)and Tara Oceans,an international community effort has been underway to launch a new global research program,BioGeoSCAPES:Ocean Metabolism and Nutrient Cycles on a Changing Planet.This initiative aims to systematically identify and quantify,on a global scale,how marine plankton respond and adapt to a changing climate and to elucidate their interactions with elemental biogeochemical cycles.
