3.2 Soil bacterial community diversity indexes
The indices, Sobs, Chao and ACE, which reflect the richness of the soil
bacterial community, have the same rule: the value in SF is
significantly higher than that in PB, and the value in CSF is
significantly lower than that in SF but is significantly higher than
that in PB (Fig. 2A, B, C). The indices reflecting bacterial community
diversity included Shannon, Simpson and pd indices. The Shannon index in
SF was significantly higher than that in PB, while the Shannon index in
CSF was not significantly different from that in SF but was
significantly higher than that in PB (Fig. 2D). There was no significant
difference in the Simpson index between SF, PB and CSF (Fig. 2E). Pd in
SF was significantly higher than that in PB, and Pd in CSF was
significantly lower than that in SF but significantly higher than that
in PB (Fig. 2F). The indices reflecting community evenness included
Shannoneven and Simpsoneven indices, and Shannoneven in CSF was
significantly higher than that in PB (Fig. 2H, I). The index reflecting
the community coverage was Coverage, and there was no significant
difference in the value of SF, PB and CSF, and the values were all close
to 1 (Fig. 2G).
