Studying the influence of altitude on soil microorganisms and enzyme activity is crucial for protecting land environmental changes in karst areas. The study focused at different altitudes Luganyou area, Baise City. Multidimensional statistical analysis encompassed assessments nutrient properties, microorganisms, enzymes across these gradients. results indicate that 0–15 cm layer surpasses 15–30 layer. Catalase, urease, cellulase exhibit consistent trends both shady sunny slopes, increasing with altitude. Alpha diversity shows abundance bacteria fungi shaded side following trend low > high In contrast, side, bacterial richness displayed a decreasing-increasing pattern rising altitude, while mirrored side. Overall, fungal exhibited slight decrease, whereas increased Across overall levels tend to increase comprehensive ecological stoichiometry indicated an elevated C/N ratio, N/P C/P ratios were relatively slopes. These findings suggest area as whole constrained by N availability. Correlation redundancy analyses revealed organic matter primary factor influencing available phosphorus are key factors affecting include total nitrogen content, well such invertase, catalase, acid phosphatase. summary, negative correlation between microbial slopes areas southwest China (160–380 m).
