Soil microbes act as “players” in regulating biogeochemical cycles, whereas environmental heterogeneity drives microbial community assembly patterns and is influenced by stochastic deterministic ecological processes. Currently, the limited understanding of soil interactions under temperate forest stand differences pose a challenge studying involvement during succession from coniferous to broad-leaved forests. This study investigated changes bacterial fungal diversity structure at regional scale identified pathways influencing their interactions. The results showed that cover forests significantly increased pH, effectively water content, total carbon (TC), nitrogen (TN), phosphorus (TP) contents. Both alpha indices were correlated with physicochemical properties, especially forest. composition was dominated process (bacteria: 69.4%; fungi: 88.9%), while (77.8%) (52.8%). Proteobacteria, Acidobacteriota, Actinobacteriota, Verrucomicrobiota dominant phyla communities Whereas Ascomycota, Mortierellomycota, Basidiomycota, Rozellomycota Most members phylum regulated physical chemical properties. In addition, conducive maintaining complex network bacteria fungi, top 20 degree major taxa reflected positive response nutrients succession. not only shows mechanism which species northern China affect processes, but also further emphasizes importance microbiome key ecosystem factor through co-occurrence analysis.
