为深入调查、评价和保护湖北药姑山自然保护区药用维管植物资源,于2012至2014年对该地区开展了系统的调查研究。结果显示,湖北药姑山自然保护区有药用维管植物143科498属968种,其中蕨类植物10科13属13种,裸子植物5科7属7种,被子植物128科478属948种。从生长型来看,草本植物最多,其次是灌木;从药用部位来看,全草类植物最多,其次是根类;按药用功效划分,以清热类、祛风湿类和活血化瘀类居多。湖北药姑山自然保护区内珍稀濒危野生药用维管植物共有57种,占药用维管植物总种数的5.89%。此外,在湖北药姑山自然保护区还发现了瑶族民间常用药用植物58种。在调查与研究的基础上,提出了加强湖北药姑山自然保护区野生药用植物资源保护与利用的措施和建议。

Diversity of Medicinal Vascular Plant Resources in Yaogushan Nature Reserve,Hubei, China

A systematic survey was conducted from 2012 to 2014 to investigate, evaluate and protect the resources of medicinal vascular plants in the Yaogushan Nature Reserve. A total of 968 species of medicinal plants belonging to 498 genera and 143 families were found, which included 10 families, 13 genera, and 13 species of pteridophytes; 5 families, 7 genera, and 7 species of gymnosperms; and 128 families, 478 genera, and 948 species of angiosperms. In regards to life form, there were more species of herbs than of shrubs. In addition, more whole plantlets than radices were utilized as the medicinal part. Most medicinal plants found in Yaogushan Nature Reserve can be used as antipyretics, anti-rheumatics, and drugs for blood-activation and stasis-elimination. There were 57 species of rare and endangered wild medicinal vascular plants, which accounted for 5.89% of medicinal vascular plants in Yaogushan Nature Reserve. In addition, 58 species of medicinal plants commonly used by the Yao ethnic group were found in Yaogushan Nature Reserve. Based on this investigation and analysis, strategies for resources protection and exploitation are discussed.
