Relationship between soil properties and the number of OTUs of main phyla in SI (Sasa-intact) and SR (Sasa-removed) plots based on a generalized linear mixed model. The response variable was the number of OTUs of the main phyla. The fixed effect was the concentration of soil properties, and the random effect was the study plot. Only significant results with p<0.05 were listed.
