Soil enzyme activities serve as the key indicators of microbial nutrient limitations. Vegetation types after farmland is returned modify both biological and abiotic properties soil, thereby impacting soil cycle stability forest ecosystems. However, limitations in degraded karst forests under different vegetation return remain unclear. Therefore, this study investigated physicochemical properties, activities, resource (grasslands (G), transitional grass–shrub (SG), shrubland (S), secondary (F)) returning on dip anti-dip slopes a trough valley. The relationships among factors influencing were analyzed to identify drivers limitation. results revealed that significantly greater than slopes. Total nitrogen (27.4%) bulk density (24.4%) influenced mainly activity its stoichiometric ratio, whereas carbon phosphorus impacted microorganisms F G types. characteristics accounted for 85.5% 75.6%, respectively, observed influence. Notably, total content (36.8%) erosion slope was other These factors, especially bedrock strata type, affect activity. This confirms type enhances slopes, providing scientific basis ecosystem restoration.
