摘　　要：概述了自20世纪30年代以来中国土壤氮素研究的某些进展。主要包括:土壤氮素的本性和氮素肥力,有机肥料氮,农田中化肥氮的去向和氮肥增产效果,农田中化肥氮的损失对环境的影响和农业生态系统的氮素平衡。土壤氮素研究的进展得益于相关学科的进展。并强调指出,对我国来说,在研究的指导思想上必须高度重视高产与环境保护的协调与统一。A summary is presented of progresses that have been achieved since the 1930s in the research on soil ni- trogen （N） in China, covering 1 ） nature of soil N and soil N fertility, 2） N in organic manure, 3） the fate and yield- increasing effect of chemical fertilizer-N applied to agricultural fields, 4） impacts on the environment of the losses of chemical fertilizer-N applied to agricultural fields, and 5） N balance in the agricultural ecosystem. It is obvious that the research benefits much from the progresses made in other relevant disciplines. And it is, therefore, stated with emphasis that the guiding ideology of the research in China must give high attention to harmonization and integration of high-yield and environment protection.
