| 英文摘要 | Rivers are an important link between terrestrial and aquatic ecosystems for nitrogen cycling, while denitrification plays a key role in riverine nitrogen removal. Denitrification was first examined in China's largest river, the Changjiang River, by using a whole-reach method. The production rates of N(2) by means of denitrification were 2.82 +/- 1.18 and 5.74 +/- 2.92 mmol(N) m(-2) h(-1) in October 2002 and March 2003, respectively, and the rates of N(2)O production were 1.98 +/- 1.48 and. 581 +/- 1937 nmol(N) m(-2) hr(-1) in August and October 2002, respectively. Nitrogen removal through N(2) and N(2)O emission accounted for 1-2% of NO(3)(-)-N flux through October 2002 to March 2003. Continued measurement throughout a whole year period after the construction of the Three Gorges Reservoir will provide more understanding of riverine denitrification and its role on controlling nitrogen export. |
