摘要：
The combined influences of species selection (Avicennia marina, Kandelia obovata) and site elevation (BSL site, below local mean sea level; ASL site, above local mean sea level) on the greenhouse gas fluxes (nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2)) from restored mangrove soils are investigated in this study. Compared with the A. marina forest, soils in the K. obovata forest at ASL site have higher CO2 fluxes, while higher N2O fluxes in the K. obovata forest are found at BSL site. The highest CH4 fluxes are found at BSL site in the A. marina forest. At each elevation site, the A. marina forest has lower CO2-equivalent fluxes and carbon release in the form of carbon-containing gases. The results suggest that A. marina should be selected for mangrove restoration to minimize carbon release and reduce influence of greenhouse gas fluxes on the global greenhouse effect.
