Microorganisms in subtropical forest soils are responsible for various ecological functions such as decomposing organic matter and driving carbon and nitrogen cycles. It is essential to understand how environmental factors affect microbial community composition and diversity. Prokaryotic communities (including bacteria and archaea) were investigated according to soil layer (0-2 cm and 18-20 cm), forest type (mountain dwarf forest, Guangdong pine forest, and monsoon evergreen broadleaf forest) and season (summer and winter) in Guangdong Nanling National Natural Reserve in China by Miseq sequencing of 16S rRNA genes. This study reveals key factors that shaped prokaryotic community structure and diversity in subtropical forest soils in China. Results show that Acidobacteria and Proteobacteria were the dominant phyla, with a relative abundance of 54.2% and 20.7% respectively. Soil pH, organic matter, total N, hydrolysable N, available P, NO3 , and NH4+ were significantly correlated with prokaryotic community structure and diversity. Soil layer significantly affected prokaryotic community structure and diversity. Forest type significantly influenced prokaryotic community structure but not diversity. Season did not significantly correlate with prokaryotic community structure or diversity.
