Abstract: From the viewpoint of soil microbial physiology and biochemistry, this paper reviewed the advances on the research of biological nitrification denitrification and nitrogen loss in rice field ecosystems. The position and significance of biological nitrification denitrification in the gaseous nitrogen losses of rice field ecosystems were also discussed. In addition, the measuring methods for the biological nitrification denitrification were compared in the paper.

Key words: Biological nitrification denitrification, Nitrogen loss, Rice field ecosystem, grain yield., wheat, irrigation regime, photosynthesis, middle growth stage, water consumption
