Diversity and Comprehensive Value Evaluation on Wild Medicinal Plant Resource in Xingyi City of Guizhou Province
[Objective]The diversity and comprehensive development and utilization value of wild medicinal plant resource in Xingyi City of Guizhou Province were explored,which provided a reference for the development and sustainable utilization of local medical plant resources.[Method]The diversity of wild medicinal plant resource and comprehensive development and utilization value of wild key medical plants in Xingyi City were analyzed by combining representative area-sample survey methods with documentary data method.[Result]A total of 150 families of wild medicinal plants in Xingyi City,belonging to 690 species and 456 genera,which were mainly composed of single-species family(55 families),micro-sized family(43 families)and medium-sized family(34 families).The perennial herbs took the most(250 species),accounting for 36.23%of the total plant species in the area,followed by shrub(180 species),accounting for 26.07%.The medical parts were mainly root and rhizome(270 species)and total herbs(177 species),accounting for 43.83%and 28.73%of the total medical plants.There were 18 families belonging to 24 genera and 26 species of medicinal plants with potentiality,and the total potentiality of wild key medicinal plants was about 6 008.64 t,among which the potentiality of Ligustrum lucidum was the most,followed by Pyrrosia lingua,Siegesbeckia orientalis,Senecio scandens,Imperata cylindrica and Polygoni multiflori caulis.There were 4 first-class protected plants(Ginkgo biloba,Cycas revoluta,Taxus wallichiana and Metasequoia glyptostroboides)and 19 secondary-class protected plants(Dendrobium nobile,Phoebe bournei and Cymbidium nanulum,etc.)recorded by List of National Key Protected Wild Plant of China,however,only G.biloba had the potentiality.There were 8 species such as G.biloba,Eucommia ulmoides,Houpoea officinalis and Xanthium strumarium with high comprehensive value,while there were 11 species such as L.lucidum,P.lingua,I.cylindrica and P.multiflori caulis with higher CVMP.[Conclusion]The medicinal plant resource has abundant diversity in Xingyi City and the comprehensive value is high.It is suggested that the key varieties with high comprehensive value are restored and utilized in a planned way.In addition,the breeding of endangered medicinal plant should be enhanced,and the gene bank and breeding base should be established at the same time.
