Soil pore space composition and nutrient status under natural formation of Castanopsis carlesii community,artificial forcing regeneration Castanopsis carlesii  community,young Chinese fir plantation and halfmature Chinese fir plantation were studied.

Based on experiment of artificial measures promoting regeneration and improve.

In order to abate and solve the contradiction of forest and mushroom radically,this paper commenced the study of cultivate the mushroom material forest,cultivate the special use forest of mushroom material in the cut natural broadleaf forest through artificial measures promoting regeneration.

The natural and artificial promoting regeneration patterns were used to study the recovery performance of Jiulongkeng sub-natural broadleaved forest in Guangze County in the aspects of community development,species biodiversity,and ecological dominant degree and key value.

paying great attention to afforestation and neglecting management and natural rehabilitation of vegetation, in afforestation of barren land, the article suggests the artificial promotion of vegetation rehabilitation as one important practice to convert farmland to forestland.
