摘　　要：从土壤微生物生理学和土壤生物化学角度综述了稻田生态系统土壤生物硝化反硝化作用与氮素损失的研究进展。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.
