3.2.1.2 Correlation analysis of main soil bacteria and
environmental factors in H. rhamnoides forests
We used the Pearson correlation coefficient to analyze the correlation
between bacterial phyla and soil environmental factors in bacterial
communities. The results of the analysis are illustrated by a heatmap in
Figure 3. The figure shows that TOC, AN, EP, and AK have a strong
influence on the content of bacteria in soil. The dominant populations,
Gemmatimonadetes, Nitrospirae, and Actinobacteria, were negatively
correlated with TOC, AN, EP, and AK. Gracilibacteria, Parcubacteria, and
WS2 were positively correlated with TOC, AN, EP, and AK.
