英文摘要Numerous efforts have been made to characterize forest carbon (C) cycles and stocks in various ecosystems. However, long-term observation on each component of the forest C cycle is still lacking. We measured C stocks and fluxes in three permanent temperate forest plots (birch, oak and pine forest) during 2011-2014, and calculated the changes of the components of the C cycle related to the measurements during 1992-1994 at Mt. Dongling, Beijing, China. Forest net primary production in birch, oak, and pine plots was 5.32, 4.53, and 6.73 Mg C ha(-1) a(-1), respectively. Corresponding net ecosystem production was 0.12, 0.43, and 3.53 Mg C ha(-1) a(-1). The C stocks and fluxes in 2011-2014 were significantly larger than those in 1992-1994 in which the biomass C densities in birch, oak, and pine plots increased from 50.0, 37.7, and 54.0 Mg C ha(-1) in 1994 to 101.5, 77.3, and 110.9 Mg C ha(-1) in 2014; soil organic C densities increased from 207.0, 239.1, and 231.7 Mg C ha(-1) to 214.8, 241.7, and 238.4 Mg C ha(-1); and soil heterotrophic respiration increased from 2.78, 3.49, and 1.81 Mg C ha(-1) a(-1) to 5.20, 4.10, and 3.20 Mg C ha(-1) a(-1). These results suggest that the mountainous temperate forest ecosystems in Beijing have served as a carbon sink in the last two decades. These observations of C stocks and fluxes provided field-based data for a long-term study of C cycling in temperate forest ecosystems.
