地球系统模型(ESM)的陆地和海洋生态系统组成部分是预测全球碳循环未来行为的关键。与陆地生态系统模型相比,海洋生态系统模型的复杂性较低。在本研究中,我们使用两种基于多种浮游功能类型的明确表示的海洋生物地球化学模型。我们对模型施加相同的未来物理扰动,并比较生态系统动态、出口生产(EP)和海洋碳吸收(OCU)对相同物理变化的响应。模型比较表明:(1) EP的变化直接转化为OCU在十年时间尺度上的变化;(2)生态系统结构的表征在连接OCU和EP方面起着关键作用;(3)OCU对赤道太平洋和南大洋生态系统的表征高度敏感。
Terrestrial and oceanic ecosystem components of the Earth System models (ESMs) are key to predict the future behavior of the global carbon cycle. Ocean ecosystem models represent low complexity compared to terrestrial ecosystem models. In this study we use two ocean biogeochemical models based on the explicit representation of multiple planktonic functional types. We impose to the models the same future physical perturbation and compare the response of ecosystem dynamics, export production (EP) and ocean carbon uptake (OCU) to the same physical changes. Models comparison shows that: (1) EP changes directly translate into changes of OCU on decadal time scale, (2) the representation of ecosystem structure plays a pivotal role at linking OCU and EP, (3) OCU is highly sensitive to representation of ecosystem in the Equatorial Pacific and Southern Oceans.
