Table 2.
The mean alpha richness and diversity indexes of the samples on OTU level.
| Sample | Species richness | Species diversity | ||
|---|---|---|---|---|
| Ace | Chao | Shannon | Simpson | |
| PBS (n=5) | 399.193 | 409.759 | 4.125 ↑ | 0.034 |
| BLM (n=10) | 417.735 ↑ | 421.874 ↑ | 4.045 | 0.047 ↑ |
| HC (n=10) | 195.317 | 178.192 | 2.548 ↑ | 0.199 |
| SSc (n=5) | 254.781 ↑ | 239.230 ↑ | 2.463 | 0.282 ↑ |
Species richness: Ace and Chao indices reflect the richness of microbial community. Species diversity: Shannon and Simpson indexes reflect the diversity of microbial communities. ↑, The average of the indexes has the similar changing trend.
