3.2.2.2 Correlation analysis of main soil fungal 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 fungal
communities. The results of the analysis are illustrated by a heatmap in
Figure 6. The figure shows that the soil environment has little effect
on the biomass of the fungal population. Ichthyosporea and Ciliophora
were positively correlated with soil environmental factors, Ascomycota
was negatively correlated with TP, Cercozoa was negatively correlated
with TN and AN, and Glomeromycota was negatively correlated with TK.
Generally speaking, compared with the bacterial community, the Pearson
correlation between the fungal community and soil environmental factors
is lower in H. rhamnoides forest; that is, environmental factors
have a greater impact on bacteria than on fungi. Conversely, the number
of species of bacteria in the soil under the H. rhamnoides forest
is higher than is that of fungi, which may be why there are more
bacteria in the bacterial community that are related significantly to
environmental factors.
