We analyzed the stable carbon concentration and carbon isotopes of organic carbon (SOC%, δ13CSOC) and BC (BC%, δ13CBC) in surface sand from deserts and dune fields in Northern China.
- •
δ13СBC has positive correlation with δ13CSOC, and is controlled mainly by surface plants.
- •
SOC% and BC% are small, and BC/SOC is high.
- •
Exogenous BC from deserts has a limited impact on BC in the CLP.
