英文摘要 | The ecosystem carbon turnover time-an emergent ecosystem property that partly determines the feedback between the terrestrial carbon cycle and climate-is strongly controlled by temperature. However, it remains uncertain to what extent hydrometeorological conditions may influence the apparent temperature sensitivity of t, defined as the factor by which the carbon turnover time increases with a 10 degrees C rise in temperature (Q(10)). Here, we investigate the responses of the ecosystem carbon turnover to temperature and hydrometeorological factors using an ensemble of observation-based global datasets and a global compilation of in situ measurements. We find that temperature and hydrometeorology are almost equally important in shaping the spatial pattern of ecosystem carbon turnover, explaining 60 and 40% of the global variability, respectively. Accounting for hydrometeorological effects puts a strong constraint on Q(10) values with a substantial reduction in magnitude and uncertainties, leading Q(10) to converge to 1.6 +/- 0.1 globally. These findings suggest that hydrometeorological conditions modulate the apparent temperature sensitivity of terrestrial carbon turnover times, confounding the role of temperature in quantifying the response of the carbon cycle to climate change. |
