By using static chamber techniques, the N2O emission from soils under different land use patterns was measured. The results showed that the N2O flux ranged from -21 to 435 microg x m(-2) h(-1), and the annual N2O flux was decreased in the order of vegetable field > orchard > upland > upland transferred from paddy field > woodland, being 447.14, 313.57, 167.00, 124.875 and 7.24 mg x m(-2), respectively. The N2O flux presented significant seasonal fluctuation, with the maximum in spring and summer, followed by in autumn, and the minimum in winter, which was approximately consistent with the changes of air- and soil temperature. N2O flux had significant positive correlation with the soil temperature at 5 cm depth and soil NO3(-)-N content, but no significant correlation with soil moisture and NH4(+)-N contents.
