| Abstract: | Significant differences are noticed in δ13C value between C3 plants and C4 plants. According to this feature, soil samples were collected from three profiles on farms and forest lands near the Maolan karst forest where C3 plants and C4 plants are growing now. Some rules of transport of soil organic carbon can be deduced in terms of the measured δ13C values of total organic carbon and different size—density fractions. |
