| In this paper,an investigation and analysis was made on the wild medicinal plant resources distributed in the Tejin Hanwula Nature Reserve by using the conventionally utilized investigation methods for plant resources and the stratum evaluation method for wild medicinal plants.The author endeavors to provide a reference for the protection and utilization of wild plant resources for this reserve area and has got the following results:(1)There are 352 species 2 subspecies 13 varieties of medicinal plant resources belonging to 72 families and 242 genera in the Tejin Hanwula Nature Reserve,including: 10 species 1 variety of ferns belonging to 5families 7 genera;4 species 1 variety of gymnosperm belonging to 3 genera and 3 genera;338 species 2 subspecies 11 varieties of angiosperm belonging to 64 families and 228 genera,among which,angiosperms are the primary part of all medicinal plants in this Tejin Hanwula Nature Reserve.From the compositions of the medicinal plants in this Tejin Hanwula National Nature Reserve,Compositae,Leguminosae,Rosaceae,Polygonaceae,and Ranunculaceae are the top five largest families and Potentilla,Artemisia and Polygonum are the top three largest genera.(2)The perennial herbaceous species dominated the life form in this area,reaching 88.56% of the total species of wild medicinal plants;in addition,the mesophytes accounted for 75.2% of the total species of the medicinal plant resources in this Tejin Hanwula National Nature Reserve.(3)Of the 352 species 2 subspecies 13 varieties of wild medicinal plants in this Tejin Hanwula National Nature Reserve,there are 346 species 2subspecies 13 varieties of TCM-related medicinal plants belonging to 72 families and 237 genera;195 species 1 subspecies 8 varieties of Mongolian drug-related medicinal plants belonging to 52 families and 132 genera;31species 2 varieties of Tibetan drug-related medicinal plants belonging to 24 families and 32 genera.(4)Based on the analysis on medicinal parts,the medicinal parts of TCM-related,Mongolian drug-related and Tibetan drug-related medicinal plants are usually the whole plant or ground part,accounting for 45.67%,37.5%,and 39.02%.On the frequencies of medicinal parts,there are differences between Mongolian drugs and TCM drugs or Tibetan drugs.The inter-type similarity indexes were calculated for these three types of plants and it found that: according to the obtained values(ie,the inter-type similarity index of the medicinal parts),the similarities between these three plants were sorted as: TCM-drugs and Mongolia-drugs(40.71%),Tibetan drugs and Mongolia drugs(17.04%),TCM drugs and Tibetan drugs(12.73%).(5)Via the establishment of an overall evaluation model for medicinal plant resources in this Tejin Hanwula National Nature Reserve,it can be aware of that there are 77 species of level one wild medicinal plants that can be utilized in this area.These 77 plants are proved belonging to various medicinal categories and possessing diverse effects.Their utilization degree is considerable and medicinal parts are various;there are respectively 170species(accounting for 46.32% of the total species in this area),108 species(29.43%)and 12 species(3.27%)of wild medicinal plants belonging to level two,three and four that can be utilized in Tejin Hanwula National Nature Reserve.Among them,the utilization value is of great significance in the research and application of medicinal plants.(6)A total of 58 species of wild medicinal plants in the reserve have been included in the Chinese Pharmacopoeia(2015),among which 11 species,34 species,and 13 species of wild medicinal plants have been developed and used in the Grade I,II,and III levels.(7)This article also proposes the protection and utilization of wild medicinal plant resources in protected areas. |
