Wildfires are significant disturbances that reshape soil ecosystems, impacting properties, microbial communities, and enzyme activities. In Pinus tabulaeformis forests in northern China, the effects of wildfire on health, particularly Actinobacteriota enzymatic functions, remain poorly understood. This study investigates both direct indirect fire severity these factors examines how fire-induced changes properties mediate responses. Our findings show significantly alters chemical including an increase pH a reduction organic carbon water content, under high severities. These directly impact with showing resilience light moderate intensities but declining severity, especially subsoil layers. Soil enzymes, such as urease protease, played crucial role mitigating negative impacts nutrient cycling. Their activity promoted availability, aiding ecosystem recovery, even intensity reduced overall fertility. Structural Equation Modeling (SEM) further revealed relationships between Actinobacteriota, shaped by thermal complex interactions mediated moisture levels. underscores importance considering mutual activities post-fire recovery. The highlight while high-severity fires disrupt health dynamics, enzymes can help regulate enhancing cycling supporting stability. insights contribute to better understanding wildfire-induced degradation provide actionable strategies for restoration management fire-prone ecosystems.
