摘要： To preliminarily study N2O emissions and the importance of environmental parameters on N2O flux from subtropical agroecosystem in China, N2O flux measurements were made at three cultivated agricultural lands in Guizhou Province, southwestern China. Based on the test and validation of daily N2O flux and its several associated variables between DNDC model and field measurements, DNDC model has been employed to estimate total N2O emissions from entire agricultural lands and its spatial distribution at county scale in Guizhou in 1995, and to assess the contributions of cropping practices on N2O emissions.
