Petroleum hydrocarbon contamination has emerged as a significant global environmental issue, severely impacting soil microbial communities and their functions. This study employed high-throughput sequencing to systematically analyze the bacterial community structure functional genes in soils with varying levels of petroleum contamination. The results demonstrated that led decline diversity, while enhancing abundance specific genes, such those involved polycyclic aromatic (PAH) degradation, methane production, denitrification. Phylogenetic analysis further revealed highly contaminated tended form clustered specialized groups, simultaneously promoting coexistence phylogenetically distant microorganisms. Mantel test identified correlations between ammonium ion concentration, moisture content, metabolic pathways, particularly related degradation These findings suggest not only disrupts carbon nitrogen metabolism balance but also profound implications for greenhouse gas emissions cycling, potentially destabilizing ecosystem. provides novel insights into ecological functions petroleum-contaminated highlights potential key factors pollution management restoration.
