[Soil microbial diversity and influencing factors of typical vegetations in the dry season of Nanling Mountains, China].

was the dominant fungal genus in ravine evergreen broad-leaved forest and montane evergreen broad-leaved forest. Chemoheterotrophy was the primary functional group for bacteria, with an average proportion of 65.3%, being higher in the ravine evergreen broad-leaved forest and montane elfin forest but lower in mixed coniferous-broad-leaved forest. For fungi, symbiotrophic and saprotrophic nutritional modes were the main functional groups, with average proportions of 46.1% and 43.5%, respectively. Symbiotrophic fungi were more abundant in the ravine evergreen broad-leaved forest and montane evergreen broad-leaved forest, while saprotrophic fungi were more prevalent in the mixed coniferous-broad-leaved forest, montane meadow, and montane elfin forest. Soil pH, total nitrogen, and total potassium were the main factors influencing bacterial communities, whereas altitude, ammonium, and nitrate were the primary factors affecting fungal communities. Altitude, ammonium, and total phosphorus were identified as key drivers of the spatial variation in soil microbial diversity under typical vegetation types in the Nanling region during the dry season.
