Soil microbial communities play a crucial role in maintaining diverse ecosystem functions within the saline-alkali soil ecosystems. Therefore, this study, we collected various saline-alkaline soils from across Inner Mongolia Hetao irrigation area. The chemical properties were analyzed, and diversity of bacteria fungi was measured using 16 S rRNA ITS amplicon sequencing. dynamic relationship between community factors analyzed ABT (Aggregate Enhanced tree) model, co-occurrence network, structural equation model. results indicated that electrical conductivity (EC) biggest driving force soils, affecting structure (22.80%) (21.30%). samples categorized into three treatment levels based on their EC values: low-salinity group (L, EC: 0–1 ms/cm, n = 10), medium-salinity (M, 1–2 8), high-salinity (H, > 2 6). demonstrated negative correlation abundance salinity-alkalinity, while revealing an enhanced interrelationship among species. alterations bacterial (12.36%) fungal (22.92%) primarily driven by ions, which served as principal direct factors. SOM exhibited highest magnitude, whereas positive organic carbon greatest strength. it further substantiated played pivotal shaping distinct soils.
