Poa alpigena Lindm is a dominant forage grass in the temperate grasslands of Qinghai Lake Basin, commonly used for grassland restoration. Soil microorganisms are crucial material cycling within terrestrial ecosystems. This study aimed to investigate effects P. on microbial community composition and structure rhizosphere non-rhizosphere soils Qingbaya area. Using high-throughput sequencing, we identified gene pools compared diversity. Metagenomic analysis showed that soil contained 35.42–36.64% known sequences, with bacteria making up 79.25% microbiota. Alpha diversity indicated significantly higher richness soil, influenced by electrical conductivity, total carbon, nitrogen content. LEfSe revealed Alphaproteobacteria Betaproteobacteria were major differential taxa soils, respectively. Key metabolic pathways related AMPK signaling, secondary metabolite biosynthesis, starch metabolism, while involved aromatic compound degradation, purine metabolism diverse environments. The enrichment functional methane oxidation suggests potential role shaping processes linked greenhouse gas regulation, although direct evidence flux changes was not assessed. Similarly, presence degradation indicates processing such compounds, but no measurements specific contaminants performed.
