3.5 Multiple drivers accounting for microbiome
A driving model is constructed based on the Spearman and Mantel test to
explore how petroleum affects and drives the diversity and composition
of soil physicochemical properties, metallome, and microbiome in the
complex soil environment (Fig. 6 ). The results showed that
after TPH entered the soil, the contents of TC and TN increased
significantly, and the bacteria decreased α diversity (p <
0.05) significantly. In addition, petroleum hydrocarbons could directly
change the soil metal group, bacterial and fungal community composition
(p < 0.05). In addition, it also indirectly affected the soil
metal group through TC and TN (p < 0.05), and the soil metal
group indirectly affected the composition of bacterial community and
fungi α diversity was affected (p < 0.05).
