青海省杂多县野生中(藏)药用植物资源分布规律与利用现状调查OA

Objective:This study aimed to investigate the distribution patterns and utilization status of wild traditional Chinese(Tibetan)medicinal plant resources in the alpine regions of Zadou County,Qinghai Province,to provide a sci-entific basis for their conservation and sustainable development.Methods:Following the Fourth National Survey Proto-col for Traditional Chinese Medicine Resources,field surveys were conducted using transect-line,plot,and quadrat sam-pling methods.A total of thirty-six randomly selected sites in Zadou County were examined to document the species composition,abundance,distribution,and utilization characteristics of medicinal plants.Results:The survey recorded 213 medicinal plant species,belonging to 136 genera and 48 families.Species from the Asteraceae,Ranunculaceae,and Fabaceae families were predominant.Herbaceous plants were the dominant life form,and the whole plant was the most frequently used medicinal part.All seven key medicinal species investigated are listed in the Chinese Pharmacopoeia(2020 edition).Among the documented species,six are included in the Convention on International Trade in Endan-gered Species(CITES),14 are on the IUCN Red List of Threatened Species,and nine are classified as endangered Ti-betan medicinal plants.Conclusion:This study systematically clarifies the status of wild medicinal plant resources in the alpine regions of Zadou County.The findings provide a scientific basis for conserving endangered,rare,and charac-teristic medicinal plants,supporting the sustainable development of the traditional Chinese(Tibetan)medicine indus-try,and informing ecological protection strategies for the Qinghai-Tibet plateau.
