| 英文摘要 | The water-air interface is the juncture whereby lake carbon (C) emissions are most active. However, the metabolic regulation of lake C exchange rates at the water-air interface remains unclear, especially for water conveyance-type lake systems that undergo dramatic alterations in water regimes. For the first time, underwater regime fluctuations. Findings show that the C exchange status at the water-air interface is regulated by the coupled connective effect of the water regime-water quality-GPP-pCO(2) effect. Compared to high-and low-water level periods, C emissions at the water-air interface were highest during the intermediate-water-level period. Moreover, this intermediate period was when this water conveyance-type lake system primarily converted basin-derived C inputs and discharged them into the atmosphere. This study also found that C emissions were most active when net ecosystem production (NEP) was close to 0. If NEP is too high (i.e., > 6 g O-2 m(-2) d(-1)) or too low (i.e., < -6 g O-2 m(-2) d(-1)), the partial pressure of carbon dioxide (pCO(2)) in water will be constrained either below or close to that of atmospheric pCO(2). |
