Table 1 The chemical properties of soil in different sites. E, D, R represent samples from native plant community, Eupatorium adenophorum and native plant mixed community, and E. adenophorum dominated community. Values (mean ± SE) followed by different letters in the same column indicate significant difference at P <0.05 level.

Fig. 1 Alpha diversity for different samples obtained at genetic distances of 0.03. The letters E, D, R represent samples from native plant community, Eupatorium adenophorum and native plants mixed habitat, and E. adenophorum dominated habitat.
Fig. 3 Composition of the bacterial community at different taxonomic levels. (A) Phylum; (B) Order; (C) Genus. In (C), different colors represent relative abundances of bacteria. D1-D4 are soils from Eupatorium adenophorum and native plant mixed community; E1-E4 are soils from native plant community; R1-R4 are from communities dominated by E. adenophorum.
