The zipped file in Dryad contains the data necessary to reproduce the statistical analyses published in the manuscript "Afforestation can lower microbial diversity and functionality in deep soil layers in a semiarid region" by Kong et al., 2022. The four datasets in the zipped file: #* Metadata.xlsx: Soil properties, bacterial alpha diversity and composition, and functions #* Network properties.xlsx: Soil bacterial co-occurrence network properties #* Network robustness.xlsx: Soil bacterial co-occurrence network robustness #* βNTI and RCbray.xlsx: Null model was used to infer bacterial community assembly processes If you have any other question about this Dataset, you can directly contanct with the corespongding authour
