Figure 8 . Effects of new afforestation under monoculture and
intercropping with G. jasminoides (a) and low-yield forests under
monoculture and intercropping with G. jasminoides (b) on
bacterial functional communities, as determined using structural
equation models. Solid lines indicate that the effects were at a
positive level, dashed lines indicate that the effects were at a
negative level. The red shades represent positive regulations, and the
blue shades represent negative regulations. Darker shades of red
represent high regulation strength, and light shades represent low
regulation strength. Asterisks indicate the significance level:
*P < 0.05, **P < 0.01, ***P< 0.001.)
