Driving Factors of Microbial Community Abundance and Structure in Typical Forest Soils of Sanjiang Plain, Northeast China

Until recently, a comprehensive evaluation of the environmental drivers on abundance and structure microbial community in typical forest soils has not been thoroughly conducted. In this study, (Mongolian oak (Quercus mongolica) soil, MOS; white birch (Betula platyphylla) WBS; poplar (Populus davidiana) WPS) Sanjiang Plain were selected to ascertain differences major factors driving soil structure. Results indicated that existed bacterial, archaeal, fungal community. Co-occurrence network analysis showed bacterial networks more complex than those archaeal networks. Unclassified Acidobacteria unclassified Pyrinomonadaceae keystone taxa networks, while Pleotrichocladium Leotia Among all factors, pH, SOM, total N exhibited dominant roles affecting bacteria, archaea, fungi. The redundancy (RDA) pH was vital factor responsible for
