In the 0\u201320 cm layer, all three intercropping patterns significantly reduced amylase activity compared to CK (\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.05). In the PAS pattern, acid phosphatase, neutral protease, and urease activities were significantly enhanced, with urease activity significantly higher in 0\u201320 cm than in the 20\u201340 cm layer. High-throughput sequencing revealed interactions among intercropping patterns, soil properties, and microbial communities. Intercropping significantly affected the structure, composition, and diversity of both soil bacterial and fungal communities. PSA showed pronounced effects on soil nutrient status and exhibited the highest bacterial and fungal ASV richness. Redundancy analysis (RDA) identified organic carbon (SOC) and total nitrogen (TN) as key drivers of microbial variation. Random forest and LEfSe analyses further identified key taxa, such as\n                      <jats:italic>Acidibacillus<\/jats:italic>\n                      and\n                      <jats:italic>Thermosporothrix<\/jats:italic>\n                      , as significantly associated with the intercropping effects. Functional prediction suggested that microorganisms may improve soil quality by regulating gene responses in \u201cMetabolism of terpenoids and polyketides\u201d and \u201cUrea Cycle\u201d pathways, as well as by secreting enzymes such as ferredoxin hydrogenase and \u03b2-mannosidase.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      Forest-medicinal plant intercropping improved soil quality and reshaped microbial communities in\n                      <jats:italic>P. elliottii<\/jats:italic>\n                      plantations.
