Network analysis for the correlation between soil physical, chemical, and microbial properties. Node colors are communities obtained from the pre-classification; each community in the network is represented by the same node color. Node sizes are obtained from the ranking degree, and wider nodes are the parentheses having more correlations with other parentheses. Red and green edge lines represent positive and negative correlations, respectively. The edge thickness represents the strength of the correlation. Corg, soil organic carbon; Nt, total nitrogen; Pt, total phosphorus; C:N, the ratio of soil organic carbon to total nitrogen; NH4+, ammonium; NO3−, nitrate; available phosphorus, available P; Hy-EEAs, hydrolases-extracellular enzymes activities; Ox-EEAs, oxidoreductases-extracellular enzymes activities; Cmic, microbial biomass carbon; Nmic, microbial biomass nitrogen; Pmic microbial biomass phosphorus; Cmic:Nmic, the ratio of microbial biomass carbon to microbial biomass nitrogen
