FIGURE 1 Soil properties during the forest succession process. Different
letters indicate significant differences (p <0.05), and
the error bars represent the standard error. TC, total carbon; SOC, soil
organic carbon; TP, total phosphorus; TK, total potassium; TN, total
nitrogen; NH4+, ammonium nitrogen;
NO3-, nitrate nitrogen; AP, available
phosphorus; AK, available potassium.
FIGURE 2 Fungal community richness (A), a-diversity (B), and evenness
(C) during the forest succession process.
FIGURE 3 The composition and differences of fungal communities at the
phylum (A, C) and genus levels (B, D) during forest succession.
FIGURE
4 Non-metric multidimensional
scaling (NMDS) of fungal community composition between different
successional stages (A) and different forest types (B).
FIGURE 5 Bar chart showing the significantly different functional guilds
during the forest succession.
FIGURE 6 Redundancy analysis (RDA) biplot integrating soil nutrients
under different successional stages. (A) Parameters represented by
longer arrows made a stronger contribution to group separation; red
arrows represent a significant effect; black arrows represent no
significant effect. (B) Double matrix correlation heatmap of
differential fungal functional guilds and environmental factors with a
significant difference. The color key represents the range of different
R values. Red represents positive correlation, and blue represents
negative correlation. *, **, and *** indicate
significant differences at 0.01 < p < 0.05,
0.001 < p < 0.01, and p <
0.00. TC, total carbon; SOC, soil organic carbon; TP, total phosphorus;
TK, total potassium; TN, total nitrogen;
NH4+-N, ammonium nitrogen;
NO3−-N, nitrate nitrogen; AP,
available phosphorus; AK, available potassium.

succession.
