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.
