This study investigates the effects of different land-use types (forest, arable land, and wetland) on key soil properties, microbial communities, nitrogen cycling in Lesser Khingan Mountains. The results revealed that forest (FL) wetland (WL) soils had significantly higher organic matter (SOM) content compared with land (AL), total phosphorus (TP) being highest FL available (AN) WL. In terms enzyme activity, AL WL showed reduced activities ammonia monooxygenase (AMO), β-D-glucosidase (β-G), β-cellobiosidase (CBH), while exhibiting increased N-acetyl-β-D-glucosaminidase (NAG) highlighting impact use dynamics. also exhibited diversity evenness AL. dominant bacterial phyla included Actinobacteriota, Proteobacteria, Acidobacteriota, Acidobacteriota most abundant Proteobacteria Network analysis complex connected network, simpler but more stable networks, suggesting influence community interactions. Regarding genes, AOA-amoA was AL, AOB-amoA enriched FL, reflecting oxidation. These findings highlight how affect structures, cycling, offering valuable insights for sustainable management.

Soil microorganisms play an essential role in vegetation succession, nutrient cycling, and ecosystem restoration. This study investigates the responses of soil microbial communities to ecological transitions from forest wetland Lesser Khingan Mountains, including mixed forest, conifer edge, natural wetland. The results indicated that soils were weakly acidic contained significantly higher organic matter, total nitrogen, available phosphorus compared other soils. bulk density increased with depth. Actinobacteria, Acidobacteriota, Proteobacteria dominated soils, respectively, showing minimal variation between depths. Principal component analysis non-metric multidimensional scaling demonstrated distinct bacterial wetlands edges. Redundancy revealed differed 15 cm 30 layers, influenced by potassium, density, carbon, phosphorus, nitrogen. Bacteroidota abundances correlated positively nutrients, while Acidobacteriota Verrucomicrobiota negatively potassium. Chemotrophic aerobic bacteria whereas fermentation-related anaerobic prevalent highlights how properties shape their functions.
