| 英文摘要 | Warm temperate forests have the large potential to sequester atmospheric carbon dioxide (CO2), but the interannual variability (IAV) of net forest ecosystem carbon exchange (NEE) of these forests is still not fully understood. In this study, we conducted eddy-covariance measurement to investigate the IAV of carbon fluxes and concurrent influencing factors in a warm temperate natural oak forest from 2017 to 2022. Our results showed that the natural oak forest was a strong CO2 sink with an increase of 27.79 g C m(-2) a(-1) in annual carbon sequestration, resulting from a larger increase in annual gross primary production (GPP) than that of annual ecosystem respiration (Re). Precipitation in spring (PPTspring) negatively influenced annual GPP, soil water content in spring (SWCspring) negatively influenced annual Re, while the water conditions had a negligible effect on annual NEE mainly because of the synchronous changes of annual GPP and annual Re. Increase of air temperature in autumn (Ta-autumn) delayed the end date of the growing season, leading to the increase in annual carbon sequestration. In addition, carbon fluxes did not significantly decrease under dramatic reduction of summer precipitation, indicating that warm temperate natural oak forest had a high resistance to seasonal drought. Our study helped to better understand the mechanisms underlying forest carbon fluxes in response to drought in the context of future climate change. |
