3.3 Correlation between soil physicochemical properties and soil bacterial community diversity indexes
Sobs, Chao and ACE were all significantly positively correlated with soil pH and SWW and significantly negatively correlated with AP (Table 1). The Shannon index was positively correlated with soil pH but significantly negatively correlated with TC, TN and AP. Pd was significantly positively correlated with soil pH and SWW and significantly negatively correlated with AP. The Simpson index was significantly positively correlated with TC, TN and AP. The Shannoneven index had a significant negative correlation with TC and TN, while the Simpsoneven index had a significant negative correlation with TC and NO3--N.
