江西兰科药用植物资源调查

调查研究江西兰科药用植物资源种类、分布、利用及资源现状,为保护与合理利用兰科药用植物资源提供理论依据。通过野外考察、线路调查、民间访问等调查方法,分别在不同季节对江西境内不同地区的兰科药用植物进行调查研究;对野外调查采集到的兰科药用植物及存放于江西各科研院校标本馆的兰科植物标本进行研究鉴定;对江西兰科药用植物资源的种类、分布地点、资源数量、药用价值与资源利用现状进行研究分析;查阅研究本草文献中有关兰科药用植物种类、药用情况等信息,参考有关兰科药用植物资源现代研究文献。江西共计分布有兰科药用植物37属93种,新增兰科药用植物19种,其中仅石斛属就增加6个药用新种。药用属占江西全省兰科属数的71. 2%,占全国兰科属数的20. 1%,药用种占江西兰科种类的76. 9%,占全国兰科药用种类的31. 2%。江西兰科药用植物资源丰富,许多种类具有很高的药用价值和观赏价值,但随着兰科药用植物资源的过度开发利用,有些野生兰科药用植物资源正面临枯竭,亟待加强科学管理与保护。

Resources of Orchidaceae Medicinal Plants in Jiangxi Province

To provide theoretical basis for protection and rational use of medicinal plants resources of Orchidaceae,we investigated and studied the existing species,distribution,utilization and resources of Orchidaceae medicinal plants in Jiangxi province. Orchidaceae medicinal plants in different areas of Jiangxi province were investigated in different seasons by means of field investigation,route investigation and folk interview. Orchidaceae medicinal plants collected from field investigation as well as Orchidaceae specimens stored in the herbariums of Jiangxi scientific research institutes were studied and identified. The existing species,distribution location,quantity,medicinal value and resource utilization of Orchidaceae medicinal plants in Jiangxi province were studied and analyzed. Orchidaceae medicinal plants in herbal literatures were consulted for their category,medicinal use and other information. Relevant modern research literatures on Orchidaceae medicinal plant resources were consulted. There were 93 species of Orchidaceae medicinal plants in 37 genera in Jiangxi province, and 19 of them were new species of Orchidaceae,including 6 species in Dendrobium alone. The number of medicinal genera accounted for 71.2% of Orchidaceae genera in Jiangxi province,20.1% of Orchidaceae genera in China,76.9% of Orchidaceae species in Jiangxi province and 31.2% of Orchidaceae medicinal species in China. There are abundant resources of Orchidaceae medicinal plants in Jiangxi province,and many species of Orchidaceae medicinal plants have a high medicinal value and ornamental value. However,with the overexploitation and utilization of Orchidaceae medicinal plant resources,some wild Orchidaceae medicinal plant resources are facing exhaustion,and need to urgently strengthen scientific management and protection.
