Based on the analysis of structural characteristics and species status in the Castanopsis orthacantha community,a primary vegetation type in the phosphorus mineral region of Fuxian Lake watershed,the paper analyzes and develops the reasonable species disposition pattern of Castanopsis orthacantha community in the abandoned phosphate mining. Results show that Castanopsis orthacantha has the prominent role in the maintenance of species composition and community structure,so it is the best species in the restoration of phosphorus mineral region. The reasonable species disposition may make the restored Castanopsis orthacantha community to be the reasonable structure,abundant species,and biosystem stability and restore the ecological service functions of the mining as soon as possible.
