The alpine steppe covers 700,000 Three years of measurements showed that: (1) CO2 efflux was 132.74 uptake was −2 O (0.142 efflux and CH4 uptake were significantly affected by the N additions, and the emission factors (EFs) of N2 O varied from 0.16 to 0.85% (0.56 Our consecutive observations quantify the alpine steppe ecosystem of the Tibetan Plateau as a vital CH4 sink. The lower EFs of N2 O in the simulated N deposition experiment confirm previous measurements at temperate grassland sites in China, implying a potential overestimation of N2 O emissions based on the IPCC default.
