Abstract

Terrestrial ecosystem respiration converts organic carbon into CO2 and increases as temperature increases, which causes a positive feedback loop that could accelerate global warming. We identify a threshold precipitation function that determines when ecosystem respiration is temperature-limited or water-limited, which helps to reduce uncertainties in climate change projections.

阈值降水函数决定了生态系统呼吸何时取决于水

陆地生态系统的呼吸作用将有机碳转化为二氧化碳，并随着温度的升高而增加，这就造成了一个可能加速全球变暖的正反馈循环。我们确定了一个阈值降水函数，它决定了生态系统呼吸作用何时受温度或水分的限制，这有助于减少气候变化预测的不确定性。
