Figure S3. Heatmap displaying the abundance of top 50 OTUs of bacterial across all the three land types after standardization: [p=log (n+1, 10), n means the average sequences number]. A, B, and C indicate sandy land, shrub land, and forest land, respectively. The bacteria taxon corresponding with each OTU is showed at the left and the letter before the taxon indicates the level of assignment (c=class, o=order, f=family, g=genus).
