| 英文摘要 | Purpose: Nitrogen deposition at rate not more than 50 kg ha(-1) year(-1) is generally considered to stimulate soil nitrifying and denitrifying microorganisms via increases in soil nitrogen content. However, this phenomenon in alpine ecosystems remains largely untested. Methods: We conducted an 8-year nitrogen deposition experiment on the Qinghai-Tibetan Plateau, with four nitrogen deposition rates of 10 (atmospheric deposition), 20, 30, and 50 kg ha(-1) year(-1). Results: The abundances of two nitrifying genes and four denitrifying genes and the N2O emission rate initially increased and subsequently decreased as the nitrogen deposition rate increased. The observed decrease in these indices at the rate of 50 kg ha(-1) year(-1) was caused by the toxicity of excessive NH4+. Conclusions: Our study demonstrates the vulnerability of alpine microorganisms under global changes. |
