Abstract:Soil carbon stored in the Tibetan Plateau appears stable under current temperatures, but it may be sensitive to global warming. In addition, different grazing systems may alter carbon emissions from subalpine meadow ecosystems in this region. Using a closed chamber dynamic technique, we measured ecosystem respiration (ER) and soil respiration (SR) rates with an infrared gas analyzer in a perennial grazing meadow (PM) and a seasonal grazing meadow (SM) at Shangri-la in the Hengduanshan Mountain area.
