摘　　要：2020-2021年,通过进行野外调查,对西藏自治区定结县陈塘沟兰科植物多样性以及生态类型进行了初步研究。结果表明:陈塘沟兰科植物种类较为丰富,共38属86种,其中双花石豆兰(Bulbophyllum hymenanthum)为中国内地行政区新记录种,另72种为该辖区新记录种;辖区兰科植物生态型以地生型兰科植物为主(47.7%)、附生型次之(36%)、半附生型较少(11.6%)、腐生型最少(4.7%)。开展此地的兰科植物调查研究,对丰富和充实保护区物种多样性,完善珠峰保护区森林生态结构功能,制定特殊植物保护策略具有重要意义,对进一步合理开发利用植物资源有着重要的现实依据。From 2020 to 2021,a preliminary study on plant diversity and ecotype of Orchidaceae in Chentang was carried out through field investigation.The results showed that there were 86 species of orchids in 38 genera in Chentang,among them.Bulbophyllum hymenanthum is a new record in China's mainland,the other 72 species were newly recorded in the area.The ecotype of orchids in the area were mainly terrestrial(47.7%),epiphytic(36%),half-epiphytic(11.6%)and saprophytic(4.7%).The investigation of Orchidaceae in Chentang was of great significance to enrich the biodiversity of the area,improve the forest ecological structure and function of Qomolangma Reserve,and formulate special plant protection strategies,which had important practical basis for further rational development and utilization of plant resources.
