Investigation on the Resources of Endangered Tibetan Medicinal Material Dracocephalum tanguticum
摘要
Abstract
Objective:To investigate the distribution and current situation of wild Dracocephalum tanguticum resources in central and southern Tibet,so as to provide guidance and suggestions for the protection of wild Dracocephalum tanguticum resources and the subsequent artificial cultivation.Methods:According to the technical plan of the fourth national survey of Chinese medicine resources,the resources of Dracocephalum tanguticum in 17 districts and counties of central and southern Tibet were investigated.Results:Among the 17 investigated counties in central and southern Tibet,wild Dracocephalum tanguticum resources was found in the 13 counties.The samples collected in this survey were Dracocephalum tanguticum var.tanguticum,and there was no distribution of Dracocephalum tangu-ticum var.nanum.The vegetation types of the population were mainly divided into shrub type,grassland type and limestone beach type,and 94 species of main associated plants were identified in 39 families.There were more common companion species in shrub type and grassland type populations.The species diversity and occurrence frequency of grassland populations were the highest.The habitats of Dracocephalum tanguticum were mainly wasteland or ridge around farmland,river valley slope and slope around village.Its wild distribu-tion sites were mostly located in the downhill position with steep slope,and the slope direction was mainly east-west semi-sunny slope.Conclusion:Although the distribution range of Dracocephalum tanguticum is wide in central and southern Tibet,the resource amount of Dracocephalum tanguticum is small.It is suggested to strengthen the protection of wild Dracocephalum tanguticum resources and carry out in-depth research on the key techniques of artificial cultivation of Dracocephalum tanguticum.关键词
