SM: soil moisture content; SBD: soil bulk density; SOM: soil organic matter; TN: total nitrogen; TP: total phosphorus; TK; total potassium. Percentage variance of species-environment relationships explained by the first two ordination axes. Correlations indicate intra-set correlations of environmental factors with the first two ordination axes. *P < 0.05; **P < 0.01.
