中文摘要	The exchange fluxes of nitrous oxide (N(2)O), nitrogen oxides (NO(x)) and ammonia (NH(3)) from a maize field with three different treatments were simultaneously measured using static and dynamic chambers in the North China Plain (NCP) from June 28 to October 11, 2009. The three treatments included control plot (CK, without crop, fertilization and irrigation), fertilizer N plot (NP) and wheat straw returning plus fertilizer N plot (SN). N-fertilizer application greatly stimulated the emissions of N(2)O, NO(x) and NH(3), with durations of about 10 days for N(2)O and NO, and about 7 days for NH(3). Fertilizer loss rates were 1.08% (NP plot) and 1.20% (SN plot) as N(2)O-N, were 1.93% (NP plot) and 0.76% (SN plot) as NO-N, and were 5.24% (NP plot) and 3.03% (SN plot) as NH(3)-N. In comparison with the NP plot, the significant low fertilizer loss rates as NO-N and NH(3)-N from the SN plot indicated that the wheat straw returning to the field could reduce NO(x) and NH(3) emissions. The molar ratio of NO/N(2)O was greater than unity for most data during the pulse emission periods induced by fertilization, and thus, nitrification was the dominant process for N(2)O and NO emissions during these periods. Considering the significant amount (>80%) of N(2)O and NOx emissions occurred during the pulse emission periods, the emissions of NO(x) and N(2)O from the investigated field were mainly ascribed to nitrification process.
