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.
