摘　　要：综述了影响土壤微生物体氮的因子,以及微生物体氮与可矿化氮之间的关系。着重讨论了土壤有机质、有机物料、氮肥、作物根系、土壤温度和湿度对微生物体氮的影响及研究进展;评价了土壤微生物体氮与可矿化氮的关系的研究结果。The factors affecting soil microbial biomass nitrogen and the relationship between soil microbial biomass nitrogen and mineralizable nitrogen are reviewed. The effects of soil organic matter, organic material, nitrogen fertilizer, crop root, soil temperature and moisture on soil microbial biomass nitrogen and the relevant study progresses are emphatically discussed. At the same time, the study results of the relationship between soil microbial biomass nitrogen and mineralizable nitrogen are evaluated in this paper.
