  • 摘要:The capacity of mangrove forests to act both as a source and sink of carbon makes them key ecosystems on the mitigation strategies against climate change. We evaluated the community structure and carbon sequestration potential of mangroves in Maasi m , Sarangani Province using distribution and diversity indices and allometric equations . A total of 1129 mangrove individuals growing in different habits were inventoried. Five species were identified, namely: Sonneratia alba , Rhizophora mucronata , Rhizoph ora apiculata , Avicennia marina , and Bruguiera gymnorrhiza . R. mucronata was the most dense (RD = 76.88%) and most frequent (RF = 44.53%) species in the area, but S. alba dominated (RO = 91.36%) in terms of basal area and was also the most important specie s (IV = 49.08%). The forest has low to moderate diversity (H' = 0.715) and evenness (E = 0.444) with only two equally abundant species (ENS = 2.044). In terms of aboveground carbon density, S. alba was significantly greater in amount (446.275 Mg C ha - 1 ) co mpared to the other species. Zone - wise, seaward stored most of the carbon mass amounting to 241.527 Mg C ha - 1 . Overall, the total aboveground carbon stock in the mangrove forest was 15.130 Gg, which is equivalent to 55.526 Gt of CO 2 . In conclusion, S. alba showed high potential of sequestering atmospheric carbon among the mangrove species identified. Meanwhile, the high forest aboveground carbon density implies high carbon sequestration activity. However, this could also mean huge amounts of carbon to be re leased back to the atmosphere if the forest is disturbed by human activities
