Abstract: Field investigations show that Amomum villosum is mainly planted in the ravine seasonal rain forest in Xishuangbanna Nature Reserve, resulting in the simplification of the vertical structure of some rain forests and the disappearance of some trees and nearly all understory trees, bushes and herbs. It is claimed that to protect the core area, Amomums should only be cultivated in some sites of the experimental area.The conservation of relatively centralized and susceptible area of the protected plants in experimental area should be managed in collaboration with local villagers.The management benefited to the improvement of the reserve should be applied in ravine area which is most suitable for developing Amomum in the core zone.The high Amomum production closely related to environment conservation is helpful to promote the participation of indigenous people in the nature conservation.
