The study focuses on a newly restored mangrove wetland ecosystem in Quanzhou Bay, examining soil CO2 concentrations and emissions using a portable gas analyzer.
The soil CO2 flux was relatively low due to the young age of the mangrove, with concentrations ranging between 557.08-2211.50 μmol mol(-1) and flux values from -0.21 to 0.40 μmol m(-2) s(-1).
Differences were observed between early and late intertidal periods, with early intertidal showing higher CO2 concentrations and a bell-shaped curve relationship between CO2 flux and concentration, indicating a peak before flux began to decline.
