Table 1 Goodness-of-fit statistics (R2) of environmental factors fitted to the nonmetric multidimensional scaling (NMDS) ordination of microbial community structure and enzyme activities. The significance was based on 999 permutations. Significant factors (P < 0.05) are indicated in bold: *P < 0.05, ** P < 0.01, ***P < 0.001
