Abstract The Heihe River Basin is a globally significant carbon pool, but its soil organic carbon dynamics is poorly understood. Soil samples taken between 2500 m and 4100 m revealed that the majority (>75%) of soil organic carbon was from 0-40 cm. It showed a negative relationship with pH and soil bulk density, and a positive relationship with altitude and soil water content, respectively. From 2005 to 2011, soil carbon content in the upper catchment decreased from 93 g/kg to 53 g/kg. These results suggest that policies should aim to reduce carbon loss by transferring it from the top- to the… More >
