Figure 3 . Relative abundance of different soil bacteria
at the phylum level. Pie chart showing the percentage of species as
designated by color (a). In the circos plot, the colors in the left
semi-circle represent the species composition, and the outermost circles
represent the grouping information. The colors of the inner circles
represent species, and the length represents the relative abundance of
the species. The right semi-circle indicates the distribution proportion
of species in different samples at the taxonomic level for that cluster,
the colors of the outermost circles represent species, the colors of the
inner circles represent grouping information, and the length represents
the fraction of that species in that cluster (b–d). The soil was
sampled from different depths (b), slope positions (c), and forest types
(d) depth and slope positon (n = 9), forest type (n = 12)). m1 (NA),C. oleifera new afforestation; m2 (GLF), G. jasminoides in
a low-yielding C. oleifera forest; m3 (LF), low-yielding C.
oleifera forest; m4 (GNA), G. jasminoides in C. oleiferanew afforestation. Twenty, soil layer at 0–20 cm depth; Forty, soil
layer at 20–40 cm depth; Sixty, soil layer at 40–60 cm depth. Here,
“others” indicates taxa with a maximum abundance of < 0.5%
in any sample.
