| 英文摘要 | Understanding the link between wetland gross primary productivity (GPP) and methane (CH4) emissions is crucial for global carbon cycle modeling, yet this coupling remains poorly constrained at a global scale due to data limitations. To address this critical gap, we compiled and analyzed the most comprehensive daily scale eddy covariance data set of GPP and CH4 fluxes. In this analysis, we define this coupling as the slope of the linear fit between carbon fixed by ecosystems and carbon emitted as CH4. Results indicate that the median lag time between CH4 emissions and GPP is 24.8 days. In terms of their coupling, for every gram of carbon fixed in wetlands, 0.03 (interquartile range: 0.02-0.05) grams of carbon are released into the atmosphere as CH4. The upscaling results indicate that the coupling in tropical wetlands is typically larger than in temperate and boreal wetlands, and the CO2-equivalent emissions of CH4 surpass the amount of CO2 absorbed through photosynthesis. These results enhance our understanding of the complex biogeochemical processes that drive CH4 emissions, offering valuable insights into the interplay between carbon fixation and emissions dynamics in wetland ecosystems. |
