| 英文摘要 | Forests are the largest biogenic methane sink, and an accurate assessment of their methane uptake capacity is essential for achieving greenhouse gas emission reduction targets and methane source/sink management. However, large uncertainties remain in most assessments of forest methane sinks owing to scarce observational data and unclear driving mechanisms. In this study, using a database of in situ forest methane fluxes and the random forest method, we studied the spatiotemporal dynamics of methane uptake fluxes in China's forests and their driving mechanisms. The annual methane uptake flux and total sink in China's forests were 287.1 (272.2 to 301.8) mg CH4 m-2 yr-1 and 0.47 (0.44 to 0.49) Tg CH4 yr-1, respectively, and were a net sink of methane. From 1982-2020, both the methane uptake flux and total sink in China's forests showed a significant upward trend. Further analysis indicated that increasing temperature and decreasing soil moisture were the main factors responsible for the elevated methane uptake fluxes in forests in China, while the rapid expansion of forest area nearly dominated the increase in China's total forest methane sinks over the 39-year period. In addition to the spatio-temporal assessment of methane uptake and knowledge of the potential driving mechanisms, this study highlights the positive contribution of climate warming-drying and afforestation to methane sink enhancement. |
