| Abstract: | Mangroves are important blue carbon ecosystems.During the restoration processes,the carbon exchange processes of mangroves are affected by climate and vegetation factors,thus show different characteristics from those of mature mangroves.In this study,we observed the characteristics of CO2 and CH4 fluxes from a restored mangrove at Pearl River estuary based on the closed-path eddy covariance system.We further analyzed the influences of environmental factors on carbon fluxes by path analysis method.The observations showed significant diurnal variations in CO2 fluxes.There were no significant seasonal variations in CO2 fluxes due to the collaborative impact of Gross Primary Productivity (GPP) and ecosystem respiration (Re).The seasonal variations of CH4 fluxes were significant.During 2019-2020,the annual CO2 fluxes were 79.4-138.4 g·m-2·a-1,and the annual CH4 fluxes were 25.1-25.9 g·m-2·a-1.Path analysis showed that GPP directly influenced the seasonal variation of CO2 fluxes.The radiation (Ra),air temperature (Ta) and vegetation index (NDVI) had indirect impact on CO2 seasonal variations.While seasonal variations of CH4 fluxes were directly influenced by Ta,Re and NDVI. |
