Abstract:: In order to study the effects of wild ginseng under forest on soil microbial community structures, active microbial mass and community structure were determined by phosphor lipid fatty acid (PLFA) in wild ginseng under forest with 5, 10, 15, 20 and 25 years old different root zone soil. The results showed the microorganisms containing the PLFA of i15:0,a15:0, 18:1ω9t, 16:0, 16:1ω9c, 18:1ω9c, br17:0, 18:2ω6 i16:0, and 16:1ω9t were dominance in microbial community in different years old wild ginseng under forest root zone soil; bacterial biomass, fungal biomass and actinomycetes biomass enhanced significantly; biomass more enhanced after 15 years old. In the community structure actinomycetes ratio of biomass increase and fungi ratio of biomass declined compared with contrasts in 20 years and 25 years. The structure of microorganisms is developing to good microenvironment for growing after 15 years.
