摘　　要：因全球范围内来自人类干扰的增加、自生的珍稀程度、特定的保育需要,了解、掌握野生兰科植物的分布状况是其全球研究和保护的优先事项。本次以西藏自治区亚东县为研究区,开展了野生兰科植物资源初步调查,并提出有效保护和合理开发兰科植物资源的建议。研究结果表明:1.亚东县共分布23属40种野生兰科植物,其中地生兰16属29种;附生兰6属10种,腐生兰1属1种。2.亚东县野生兰科植物划分为8个分布区类型,由南之北随海拔升高,100 km内由热带区系过渡到北温带区系,以北温带区系成分占主导,且东亚区系特征明显。3.结合国际自然保护联盟红色名录等文献查阅上兰科的研究,确定了紫点杓兰、白唇杓兰、短距手参、耳片角盘兰、高茎卷瓣兰、方唇羊耳蒜等是亚东县重点保护和研究、开发对象。Because of the global increase in human disturbance,the rarity of wild orchids,and the specific conservation needs,we need to understand and grasp the distribution of wild Orchidaceae,which is a global research and conservation priority.This time,our team took Yadong County(Xigaze,Xizang Autonomous Region on the Qinghai-Xizang Plateau)as the research area to carry out a preliminary investigation of wild orchid plant resources.After analysis,we put forward suggestions for effective protection and reasonable development of Orchidaceae resources in view of the problems found.The results:(1)There are 40 species in 23 genera in Yadong County.Including 10 epiphytic types,29 terrestrials and 1 saprophytics.(2)We divided them into eight distribution types.With the elevation increasing from south to north,these Orchidaceae transition from tropical flora to northern temperate flora within100km.It is dominated by the 8North Temperate,14E.and Asia,Sino-Himalaya(SH)is obvious.(3)We can focus on the protection and research and development of objects,Cypripedium guttatum,Cypripedium cordigerum,Gymnadenia crassinervis,Bulbophyllum elatum,and Liparis glossula.
