英文摘要	Afforestation influences soil aggregates and the soil microenvironment, and it also affects soil bacterial communities. However, the interactions between soil aggregation, soil properties, and the bacterial community that occur following afforestation are still unclear and are rarely studied in karst ecosystems. Soil samples were collected from cropland, for reference, and from natural secondary forests and managed forests in a karst rocky desertification region of Southwest China. Soil aggregates were isolated using the wet-sieving method, and the soil bacterial community composition was determined using high-throughput 16S rRNA sequencing. Afforestation promoted significant macro-aggregation (p < 0.05) and increased the soil organic carbon (38%), nitrogen (35.4%), exchangeable Ca (78.6%), and soil water contents (4.1%) but decreased the pH and bulk density. The changes in these soil aggregates and soil properties had marked effects on the abundance and composition of the bacterial community. Variation-partitioning analysis showed that, together, the soil aggregates and soil characteristics explained 23.4% of the variation in the bacterial community, and their interaction formed the largest contribution (14.6%). Overall, our findings suggest that both natural and managed afforestation may shift soil bacterial communities by promoting significant macro-aggregation and altering soil properties.
