摘　　要：奥陶纪与志留纪(O/S)转折期大气、陆地和海洋系统均发生了剧烈变化,并伴随着剧烈碳循环扰动和大规模海洋黑色页岩沉积,是地球宜居性演变的关键时期。海洋初级生产力是地球生态系统中的关键组成部分,对地球表层系统的碳循环和黑色页岩形成具有重要作用。概括O/S转折期地质背景,阐述该时期海洋初级生产力的国内外研究现状、主要发展趋势,根据我国的研究现状及特点,提出进一步开展研究工作的建议和切入点,为该时期海洋初级生产力的相关研究提供参考。研究有助于增强对当今全球气候变暖背景下海洋初级生产力影响碳循环和地球宜居性演变过程的理解和预测能力。The Ordovician and Silurian(O/S)transition was a critical period for the evolution of Earth's habitability,yielding significant perturbations in atmospheric,terrestrial and marine systems,as well as severe carbon cycle perturbations and large-scale marine black shale depositions.Marine primary productivity is a key component of the Earth's ecosystem and plays important roles to the carbon cycle and black shale formation of the Earth's surface system.By summarizing the geological background of the O/S transition,together with the research status and main achievements of marine primary productivity in both China and other countries,this paper proposes some suggestions to move on the research on exploring marine primary productivity near the O/S transition.It would be a great contribution to the understanding and prediction of the impact of ocean primary productivity on the evolution of the carbon cycle and the Earth's habitability under the nowadays global warming conditions.
