摘要: 以生物固氮为切入点,采用文献挖掘的方式,阐述固氮微生物在喀斯特生态系统中的特点和功能,重点探讨在喀斯特地区石漠化恢复过程中土壤微生物及固氮作用与植被和土壤的相互关系。对石漠化治理中土壤微生物的调控进行阐释。结果表明,喀斯特地区不同石漠化阶段具有不同的土壤微生物特征,其与土壤理化、植被类型的关系处于动态变化,土壤微生物在调控土壤“氮、磷”的过程中起到主导作用。

关键词: 喀斯特, 石漠化, 土壤微生物, 生物固氮, 根瘤菌

Abstract: Used biological nitrogen fixation as the entry point, the characteristics and functions of nitrogen-fixing microorganisms in karst ecosystem were expounded by means of literature mining. The relationship between soil microbial and nitrogen fixation and vegetation and soil in the process of rock desertification restoration in karst area was discussed. The regulation of soil microbes in the treatment of rocky desertification was explained. The results showed that different rocky desertification stages in karst area had different soil microbial characteristics, and their relationship with soil physical and chemical properties and vegetation types was dynamic, and soil microbes play a leading role in regulating soil “nitrogen and phosphorus”.

Key words: karst, rocky desertification, soil microorganism, biological nitrogen fixation, rhizobium
