Fig. 1

The relative abundance of soil bacteria at the phylum and genus levels under different N addition levels across soil layers. “B” represent the bacteria, the acronym of “1”, “2”, and “3” represent soil depths of 0 ~ 5 cm, 5 ~ 10 cm, and 10 ~ 20 cm. Additionally, CK, LN, MN, and HN correspond to control and three N addition levels, respectively. Figure (a) and (b) represent the structural compositions of soil phylum and genus bacteria, respectively.
