Abstract:: The distribution，ecological characteristics and survival situation of Anoectochilus roxburghii were investigated by combining interview investigation with field investigation in Guangxi.The results showed that the A.roxburghii distributed widely in the most evergreen broad-leaved forest of Guangxi non-limestone mountainous region,it didn’t be found in the western limestone mountainous region，but there was a similar species of Anoectochilus.A.roxburghii live in humus layer of evergreen broad-leaved forest where were shady and cool ecological condition，tree coverage was 70%-90%，light intensity was 350-2 500 lx，air relative humidity was 70%-85%.The specie of habitat tree were comprised of Fagaceae，Momceae，Lauraceae，Magnoliceae，Amliaceae.The main causes for this endangered status were the adverse change of the natural environment and the human excess collection activities，various effective measures should be adopted to protect wild resources of A.roxburghii in order to ensure the sustainable utilization of it.
