摘要
海洋表层叶绿素a浓度和浮游植物初级生产力是海洋生态系统的基础参数,可有效评估海洋生态系统的初级生物量及其变化。阐明北冰洋浮游植物生物量和初级生产力的时空变化,对预测北极环境快速变化背景下的海洋生态系统潜在变化、科学指导北冰洋的生态管理具有重要意义。本文总结了基于卫星数据的海表叶绿素a浓度和初级生产力的研究方法,整理归纳了近年来北冰洋叶绿素a浓度和初级生产力的时空变化特征,未来可通过遥感技术与生态模型结合,融合多元观测手段,重点开展北冰洋冰缘区浮游植物时空演变过程与机制研究,为更好地认知北冰洋生态系统及其气候变化响应提供支撑。
As important parameters of the marine ecosystem and its functional structure,knowledge of the chlorophyll a(Chl a)concentration and phytoplankton primary production is crucial for evaluation of marine ecosystem status.Understanding of the spatiotemporal changes of both Chl a concentration and primary production in the Arctic Ocean is of great importance regarding the improvement of our knowledge of the marine ecosystem and its response to ongoing climate change.Hence,in this study,we considered the various approaches that use ocean color remote sensing to estimate the Chl a concentration and primary production in the Arctic Ocean.The variations of Chl a concentration and primary production in recent years on both temporal and spatial scales were summarized to provide perspective regarding the biogeochemical changes occurring in the Arctic Ocean and their impact on the marine ecosystem.
