| 摘 要： | N_2O emission from soil is affected by many factors. In this study, N_2O flux, soil temperature, water content, NO_3~- and NH_4~+ concentrations were simultaneously measured in winter wheat field. N_2O flux, NO_3~- and NH_4~+ concentrations were all lognormally distributed, while water content was normally distributed. The relationship between N_2O flux and soil factors was also studied. N_2O flux was most highly correlated with soil temperature. Regression model was developed to explain the variability of N_2O emission from agricultural soil using multifactorial analysis.
