The associations between the diversity (Shannon index) and community structure (nonmetric multidimensional scaling 1 (NMDS1)) of abundant and rare soil bacteria in different land uses. Primer pair 520f/802r targeted the V4 region of the 16S rRNA gene; primer pair 338f/806r targeted the V3–V4 region of the 16S rRNA gene. The red crosses indicate nonsignificant correlations, and the size of the squares suggest higher Pearson coefficients. MAP, annual mean precipitation; MAT, annual mean temperature; SOC, soil organic carbon; EC, electrical conductivity; AVP, soil available phosphorus; TN, total nitrogen; TP, total phosphorous; NO3N, nitrate nitrogen; NH4N, ammonia nitrogen; abu, abundant bacterial taxa; rare, rare bacterial taxa; entire, the entire bacterial community.
