| Abstract: |
| Nitrous oxide(N2O) emission plays an important role in global climate change and nitrogen cycle. Soil is the main source of N2O emission and also acts as N2O negative emission, namely N2O absorption and consumption. This paper reviewed soil N2O consumption, and analyzed the physical, chemical and biological pathways of N2O consumption. The biological pathway of N2O consumption was proposed as the dominant path. The microbial mechanisms of the nitrification and denitrification processes and the environmental factors influencing the activity of microorganisms in these processed, such as the ratio of soil oxygen to water, C/N, pH, etc, were emphatically discussed. Due to complicated biological communities generating and consuming N2O, research directions and methods of N2O uptake and consumption are also suggested. |
