Grassland is the significant composition of the terrestrial carbon pool. Its belowground carbon turnover process is sensitive to land use changes and has a huge impact on atmospheric CO2 contents. However, the interpretation of the vertical distribution of δ13C values of soil organic carbon (SOC-δ13...
