This study aimed to reveal the effects of crude oil addition on characteristics soil microbial communities and ecosystem multifunctionality in Achnatherum splendens Pennisetum alopecuroides . Specifically, it explored how influences relationship between nutrient regulation, community characteristics, multifunctionality. The results indicated that as increased, Shannon index Chao1 for bacteria fungi both increased. Conversely, while archaea species decreased. ecological network analysis a strong collaborative existed bacterial exposed 10 g/kg oil, well fungal archaeal 40 oil. A was also observed exerted significant direct negative regulatory effect , had positive effect. Additionally, showed decline with increasing addition. is likely due higher toxicity high-concentration which negatively impacts biological community, leading reduced biodiversity disruptions cycles. explores bacterial, fungal, under different levels can provide theoretical support evaluating restoration from pollution.
