| 英文摘要 | Underestimating the magnitude of global lake carbon (C) production undermines the evaluation of the terrestrial ecosystem's C sink, which is key to achieving global C balance. Quantifying the potential response of lake net ecosystem productivity (NEP) and associated C production capacity to human activities is critical for evaluating the Earth's C balance. Here, we reveal global spatiotemporal dynamics of lake C production over 20 years across different continents and climate zones, highlighting the role of anthropogenic activity as a driving mechanism. We estimated lake C production using phytoplankton primary productivity from the surface to the estimated euphotic depth (PPeu) based on chlorophyll-a (Chl-a) content. Economic development has significantly contributed to increases in global lake temperatures and total phosphorus concentrations. This has stimulated increases in annual lake C production, rising from 1.53 Pg C yr- 1 in the 2000s to 1.95 Pg C yr- 1 in the 2010s. Concurrently, lakes with higher total phosphorus (TP) concentrations (>= 0.6 mg L-1) exhibited significantly greater PPeu values of 3.16 g C m- 2 d-1, compared to lakes with lower TP concentrations (<= 0.1 mg L-1), which showed 1.50 g C m- 2 d-1. Although lake water TP concentrations can reach up to 1 mg L-1, the critical TP concentration (TPc) at which global lake PPeu peaks at 4 to 6 g C m- 2 d- 1 is approximately 0.5 mg L-1. Exploiting the C sink potential of lakes requires understanding the environmental factors that control metabolic processes; however, there is a lack of effective monitoring and evaluation of the highly heterogeneous and diverse autotrophic C fixation processes in inland waters. |
