英文摘要	We measured carbon dioxide (CO2) fluxes across air-water interface with floating chambers in Lake Medo (a small, shallow lake in peatland) on the eastern Tibetan Plateau in the warm season of 2009. During the study period, mean CO2 fluxes was 488.63 +/- 1,036.17 mg CO2 m(-2) h(-1). The flux rate was high compared to those of lakes in other regions, and represented a "hotspot" of CO2 evasion. Temporal variation of CO2 flux was significant, with the peak value in the beginning and lowest point in the end of warm season. High concentration of dissolved organic carbon (DOC) in lake water (WDOC) was found to highly correlated to CO2 flux (R = 0.47, P < 0.01, n = 54). Besides, fluorescence index of WDOC showed its terrestrial origin character. In accordance with lakes in northern and boreal regions, terrestrial DOC concentration in water column was the most important regulator of CO2 flux from this lake. We suggest that large area of peatlands in catchments support high concentration of DOC in this lake, and consequently high CO2 evasion.
