|---|---|---|---|
| Köppen climate type | 16.885 | <0.001 | 0.053 |
| Vegetation type | 13.267 | <0.001 | 0.037 |
| Soil type | 13.094 | <0.001 | 0.029 |
| PM2.5 | 88.845 | <0.001 | 0.028 |
| Precipitation | 65.764 | <0.001 | 0.021 |
| Greenness fraction | 38.555 | <0.001 | 0.012 |
| Annual average temperature | 33.838 | <0.001 | 0.011 |
The associations were conducted by permutational multivariate analysis of variance (PERMANOVA) based on the Bray–Curtis distances. The statistical significance and F-statistics were calculated, using 999 permutations.
