摘要：
NO is an important greenhouse gas, its major anthropogenic source is agricultural soils and its emissionsare primarily influenced by climate and agricultural practice. This study chose a corn-rape rotation, asoybean-winter wheat rotation and a fallow field in Guizhou Province, westsouthern China as NO emissions from subtropical agricultural soils study plots. Based on the success of test and validation exercise ofmeasured and Decomposition-Denitrification(DNDC) modeled NO emission, and several associatedvariables, from above study fields exhibiting similar trends and magnitudes, we expanded DNDC modelto systematically assess the potential effect of variations in climate and farming practice in future on NOemissions from subtropical agricultural soils as above three study fields case study. The baseline condi-
