摘　　要：草地生物固氮不仅是草地生态系统氮素循环输入过程的重要部分，而且与集约化草地畜牧业的建立和退化草场的恢复有着重要的关系。在草地生态系统生物固氮的３种方式中，豆科植物根瘤共生固氮是重要方式，细菌自生固氮值得重视。Grassland bio-nitrogen fixation not only is a important part of grassland ecological systemnitrogen cycle, but also has a important relation with intensive grassland animal hsubandry construction and regressive grassland rocovery. Rhizobia nitrogen fixation in common of leguminous plants is a important mode, bacteria nitrogen fixation by themselves should be pay more attention, and nitrogen fixation in combination owns extensive application preview and potential ability in grassland bio-nitrogen fixation.
