Abstract: Land use change (LUC) is the most dynamic force in terrestrial carbon stock change, and it is imperative to account for the dynamics of LUC in carbon stock change when forming land use policies. This paper explored the impacts of LUCs on carbon (C) stocks at a county scale and detected changes of soil C stocks within a county-scale land use planning policy. The LUCs within 1979–2006 in Fuyang County (eastern China) and Fuyang Land Use Master Planning (FLUMP) (2006–2020) were selected for this pilot study. The estimates of C stock changes were examined by compiling vegetation and soil organic C density data from six land use types, and through literature reviews and field surveys. The results showed that LUCs between 1979 and 2006 already caused a vegetation carbon (VC) decrease of 273.44 Gg and a soil organic carbon (SOC) decrease of 771.01 Gg, mainly due to urbanization processes. Further, the FLUMP (2006–2020) is expected to lead to a potential C loss of 25.93 × 10 −3 Mg C ha −1 year −1 for vegetation and 27.48 × 10 −3 Mg C ha −1 year −1 for soil between 2006 and 2020. As the situation stands, it is urgent to devise rational policies and effective measures to reverse the C loss process.
