The differences in the soil diazotrophic community composition between the riparian wetlands and the alpine meadows. (A) Soil diazotrophic community compositions at the family level in the riparian wetlands and the alpine meadows. (B) The NMDS ordination combined with envfit analysis of diazotrophic community structure in the riparian wetland and the alpine meadow soils. TC, soil total carbon content; TOC, soil total organic carbon content; TIC, soil total inorganic carbon content; TN, soil total nitrogen content; TK, soil total potassium content; MBC, soil microbial biomass carbon content; MBN, soil microbial biomass nitrogen content, and moisture: soil moisture content; PC, plant coverage. (C) The differences in the relative abundance of diazotrophic taxa between the riparian wetland and alpine meadow soils at the taxonomic levels from phylum to genus. The differences were revealed through the Wilcoxon test (P < 0.05). ***P < 0.001.
