Abstract
Quantifying the C storage in mangrove forests is important to understand their ecological roles in climate change mitigation. The present study aims to determine the whole ecosystem C storage and to examine factors influencing on the sedimentary C stocks in Dong Rui mangrove forests (DRM), northeastern Vietnam. The mean above- and below-ground C stock was 48.6 ± 11.7 and 554.8 ± 112.2 MgC ha−1, respectively. In which, the sediment C pool contributed >80% proportion to the C storage. The covarying C/N ratios, δ13C and sediment compositions suggested that sedimentary OC were mainly originated from in situ productions. Results emphasized that the DRM has an important role in C sequestration and offsetting atmospheric CO2 concentration and should be included in the climate change mitigation programs.
