| Abstract: |
| Using the methods of average sample tree, sample plot harvesting and profile sampling, we determined
Syzygium samarangense orchard ecosystem in Sanya, including biomass and carbon concentration of tree layer, litter layer
and soil layer, and calculated carbon storage. The results indicated that total carbon storage of S. samarangense orchard
ecosystem in Sanya was 76.87 t/hm2, with 11.63, 1.21 and 64.03 t/hm2, accounting for 15.13%, 1.57% and 83.30% of the
total in tree layer, litter layer and soil layer, respectively. The carbon storage in plant organs was in order as branch>root>
leaf>stem>fruit, and decreased with depth of soil increasing. S. samarangense orchard ecosystem in Sanya has a significant
potential in carbon sequestration, and soil layer accounted for the largest part of the total carbon storage. Branch and root
have more carbon storage in tree, and litter layer has less carbon storage in S. samarangense orchard ecosystem. |
