The characteristics of soil microbial distribution of different planted forest have been researched on the base of the methods of typical region investigation

experimental study in site

and laboratory analysis samples. Impact of conifer problem of much area on biological diversity and the distribution pattern of soil profile microbial community in planted forestland of conifer forest (Pinus massonniana)

broad-leaved forest and mixed forests have been analyzed and discussed. The effective way and countermeasures of vegetation rebuild and ecological restoration have been put forward.
