Objective:To clarify the current distribution status of wild Chinese(Tibetan)medicinal plant resources in Ngari Prefec-ture,Xizang,so as to lay a solid data foundation for the protection,rational utilization of wild Chinese(Tibetan)medicine plant re-sources in this area and the development of the industry.Methods:A comprehensive general survey of wild Chinese(Tibetan)medicinal plant resources in Ngari Prefecture was conducted through methods such as field surveys and standard plot surveys,the specimens was collected,the species identification and specialized analyses on species groups,species composition,life forms,medicinal parts,etc were carried out.Results:A total of 592 species of wild Chinese(Tibetan)medicinal plants were recorded in Ngari Prefecture,belonging to 240 genera,73 families,with angiosperms as the dominant group.The species composition was characterized by a relatively large propor-tion of monotypic families and oligotypic families.The living types were mainly perennial herbaceous plants,accounting for 74.66%of the total number of species.The medicinal parts were mostly whole plants,accounting for 63.18%of the total number of species.There were 13 species of medicinal plants under national second-class protection,16 species of medicinal plants recorded in Convention on In-ternational Trade in Endangered Species of Wile Fauna and Flora,29 species of medicinal plants listed by IUCN Red List of Threatened Species,and 16 species of endangered Tibetan medicines.Conclusion:The wild Chinese(Tibetan)medicinal plant resources in Ngari Prefecture are rich in species,with unique characteristic Tibetan medicinal resources,and possess certain potential for industrial devel-opment.However,due to the influence of the high-altitude,cold and arid natural environment and climate change,it is urgent to build a scientific protection and sustainable utilization system.
