砂仁生产对西双版纳自然保护区的影响

调查研究表明 ,西双版纳砂仁种植主要在沟谷季节性雨林林下 ,它造成局部雨林垂直结构层次简单化 ,使中层乔木部分树种和几乎全部下层乔木、灌木和草本植物种类流失 .种植砂仁只能在试验区内一般地段进行 ,严格保护核心区 .在试验区确定保护植物相对集中的敏感地段和村民共同管理 ,在核心区最适宜发展砂仁的沟谷地段重点巡护有利于提高保护区的管理水平 .砂仁高产与环境保护关系密切 ,有利于提高当地村民参与自然保护的自觉性 .

Impact of Amomum production on Xishuangbanna Nature Reserve.

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.
