Abstract
To preliminarily study N2O emissions and the importance of environmental pa
rameters on N2O flux from subtropical agroecosystem in China, N2O flux meas
urements were made at three cultivated agricultural lands in Guizhou Provin
ce, southwestern China. Based on the test and validation of daily N2O flux
and its several associated variables between DNDC model and field measureme
nts, DNDC model has been employed to estimate total N2O emissions from enti
re agricultural lands and its spatial distribution at county scale in Guizh
ou in 1995, and to assess the contributions of cropping practices on N2O em
issions.
