| 英文摘要 | In this paper, CH4 flux was measured from Nov. 2002 to Oct. 2005, to estimate CH4 emissions in winter and during freeze-thaw period, and interannual variation in CH4 emissions in freshwater marsh in northeast China. The results showed that there was an obvious CH4 emission (0.1-2.3 mg m(-2) h(-1)) in the freshwater marsh in winter. Flux of CH4 in winter (November to March the next year) was about 3.8%, 5.5%, and 2.2% of the whole year in 2003, 2004, and 2005, respectively. Emission of CH4 significantly increased during the freeze-thaw period (April-June), and was about 30.8%, 20.9%, and 20.6% of the whole year in 2003, 2004, and 2005, respectively. Standing water depth greatly governed interannual variation of CH4 emissions from marshes during the thaw-freeze period. Interannual variation of CH4 emissions was significant during the growing season (p < 0.05). Standing water depth during April to June was a primary factor, which affected the interannual variation of CH4 flux during the growing season. Precipitation during the preceding non-growing season affected CH4 emission indirectly via standing water depth. (c) 2006 Elsevier B.V. All rights reserved. |
