5 CONCLUSIONS
In summary, there is a strong relationship between the bacterial community structure and the multifunctional resistance of soil. The most significant predictor of multifunctional resistance within the ecosystems studied is the relative abundance of oligotrophic bacteria, Verrucomicrobia and Chloroflexi being the most important. Regrading specific ecosystem functions, Chthonomonadetes, Chloroflexia and OPB35_soil_group were the best predictor of total organic carbon, total nitrogen and total phosphorus, respectively. The interplay among bacterial community and soil attributes modulates the rates of soil nutrient cycles, which promotes the ultimate maintenance of multifunctional resistance. In summary, this study suggests that maintain microbial diversity can mitigate the negative impacts of land use on multifunctional resistance of ecosystem.
