Figure 1. The relative abundances of major taxonomic groups at the phylum level for bacteria across all land-use types in winter and summer.

Relative abundances are based on the proportional frequencies of bacterial DNA sequences that could be defined at the phylum. Site abbreviations starting with S and W indicate sampling in summer and winter, respectively. The land use types and their abbreviations are: oak forest (SO and WO), oriental arborvitae forest (SA and WA), black locust plantation (SL and WL), shrub land (SS and WS), and bare land (SB and WB) respectively. The figure is generated by using the R v.3.1.3 project (R Development Core Team. 2015).
