As a perennial plant, the nutrient supply for tea bushes is predominantly dependent on soil. Yunnan plantations exhibit significant topographic slope variations, yet combined impact of positions soil chemistry and microbial communities remains unexplored. This study investigated chemical properties community structures across three distinct areas within single plantation. The results showed that contents organic matter (OM), total nitrogen (TN), available nutrients (AN) at top (TS) were significantly higher than those foot (FS) (p < 0.001), while cation exchange capacity (CEC) potassium (TK) reached peak levels in middle (MS), with FS having lowest levels. Redundancy analysis (RDA) indicated bacterial primarily influenced by TK, magnesium (Mg), CEC, phosphorus (TP), pH, whereas fungal mainly regulated Mg, highlighting role shaping diversity distribution. Bacterial composition no slope-related differences, but varied notably family/genus MS exhibited highest network complexity, suggesting stronger species interactions. metabolic functions trophic modes conserved regions, indicating functional stability independent structural changes. reveals slope-driven soil-microbial dynamics plantations, offering insights into assembly adaptation under gradients. These findings support precision fertilization, ecological conservation, sustainable management plantations.
