Statistics
Resistance was defined as the natural logarithm of the ratio of Bray-Curtis distance between O-U1 to T1-U1, the resilience was defined as natural logarithm of ratios of Bray-Curtis distance between T1-U1 to T2-U2, as shown in Fig. S1.
Network analyses were conducted in in a pipeline (http://www.magichand.online/h5-BioCloud-site/#/) and visualized by Cytoscape 3.3.0 (http://cytoscape.org/). The cutoff threshold was set at 0.9, top 100 relative abundance OTUs of the bacterial and fungal community were selected for network analysis by Spearman correlation matrix. The interaction type ratio was defined as the proportion of positive interactions to all interactions (P%). Thus, a P% of approximately 0.5 indicated relatively equal (balanced) proportions of positive and negative interactions, while a P% near 1 or 0 indicate an exceedingly high proportion of positive or negative interactions, respectively. The significant difference of basic soil properties and diversity indexes among ecosystems were checked using one-way ANOVA test. PCoA analysis were based on Bray-Curtis distance, was performed using a pipeline (http://www.magichand.online/h5-BioCloud-site/#/). In order to unify bacterial and fungal richness, we used the standard richness for relative analysis, which was defined as the ratio of richness to the lowest richness from bacterial and fungal samples, here is the fungal community richness of the 3rd sample of bare land (only 563).
