Abstract BackgroundAn insight into the soil microbial functions and spatial distribution of soil resources is an important basis for evaluating and managing plant growth in subtropical forests. Soil samples were collected from five forest stands in Jinyun Mountain Natural Reserve (JMNR) in Chongqing located at the Three Gorges Reservoir area: Gordonia acuminata evergreen broad-leaved forest (GAEBF), Cunninghamia lanceolata forest (CLF), Phyllostachys pubescens forest (PPF), coniferous and broad-leaved mixed forest (CBLMF) dominated by Pinus massoniana and Gordonia acuminata (PM&GA), and the CBLMF dominated by Pinus massoniana and Symplocos setchuensis (PM&SS). Combined with phospholipid fatty acid (PLFA) analysis and Sherlock microbial identification system (MIS), the structure of soil microbial communities in different forest stands was investigated.ResultsThe results showed that the PLFAs of soil microorganisms under the forest in JMNR have a high diversity. The PLFA dominance values of the five stands were 16:0, 19:0 cyclo ω7c, 18:0, 15:0 iso and 16 :0 10-methyl. Furthermore, soil microorganisms are dominated by Gram-negative bacteria, and the PLFAs content of soil bacteria in different forest stands is higher than that of fungi PLFAs. Regarding the phospholipid fatty acid biomarkers, the two CBLMFs are the highest, followed by CLF and GAEBF and PPF is the least. Moreover, the proportion of microorganisms in the soil of different forest stands varies. Among them, MP&SS has the highest gram-negative bacteria, gram-positive bacteria, actinomycetes and fungi.ConclusionsRDA analysis shows that the main influencing factors of PLFAs in the soil of different forest stands are the content of iron oxide, aluminium oxide, organic matter and total nitrogen in the soil, which are considered to be able to reflect the soil nutrient status of JMNR effectively.
