Response of Soil Respiration to Grazing in an Alpine Meadow at Three Elevations in Tibet
Figure 2
Effects of grazing on dissolved organic C (DOC, mg kg−1), dissolved organic N (DON, mg kg−1), the ratio of DOC and DON (DOC/DON ratio), nitrate N (-N, mg kg−1), ammonium N (-N, mg kg−1), soil available N (SAN, mg kg−1), the ratio of -N and -N (-N/-N ratio), and belowground root biomass (BGB, kg m−2) in an alpine meadow at three elevations (i.e., 4313 m, 4513 m, and 4693 m) on the Tibetan Plateau. Error bars represent standard error (). MBC and SOC data were obtained from Fu et al. [22].
