AB  - Land use change obviously changes the plant community composition and soil 
      properties of grasslands and thus affects multiple functions and services of 
      grassland ecosystems. However, the response mechanisms of soil microorganisms, 
      key drivers of the nutrient cycle and other soil functions during changes in 
      grassland use type and associated vegetation are not well understood. In this 
      study, Illumina high-throughput sequencing was used to analyze the changes in the 
      soil microbial community structure of four grassland use types: exclosure (EL), 
      mowed land (ML), grazed land (GL), and farmland (FL) in the Songnen Plain of 
      Northeast China. The results showed that the FL and EL had significantly higher 
      soil total nitrogen (TN) and lower soil electrical conductivity (EC) and pH than 
      GL and ML. In contrast, the GL and ML had higher soil bulk density (BD) and 
      organic matter, respectively, than the other land use types. In addition, the 
      values of the Shannon diversity and Pielou's evenness indexes were highest in the 
      EL of all the land use types. Based on the high-throughput sequencing results, we 
      observed high levels of alpha diversity in the FL for both bacteria and fungi. A 
      structural equation model (SEM) revealed that pH and EC had a direct and positive 
      effect on the bacterial community structure and composition. In addition, plant 
      taxonomic diversity (according to the Shannon diversity and Pielou's evenness 
      indexes) indirectly affected the bacterial community composition via soil pH and 
      EC. Notably, fungal composition was directly and positively correlated with soil 
      nutrients and the value of Pielou's evenness index changed with land use type. In 
      conclusion, soil properties and/or plant diversity might drive the changes in the 
      soil microbial community structure and composition in different grassland use 
      types.
