The Investigation Of Medicinal Plant Resources In Yixian Country Of Anhui Province

Object:In order to provide a scientific basis for the protection,utilization and development of traditional Chinese medicine resources in Yixian,combined with the local ecological environment,we investigate the species,distribution and harvest of medicinal plant resources,and understand the market of Chinese medicinal materials.Method:Referring to the "technical specification for the fourth national census of traditional Chinese medicine resources",field investigation and visit investigation are carried out.To investigate the distribution of medicinal plants in different ecological environment and seasons,estimate the reserves of some key Chinese medicine in Yixian.And the results of the investigation are scientifically sorted out and identified.Result:A total of 1073 medicinal plant specimens from 8 villages and towns in Yixian were collected and identified,which belong to 788 species of 159 families,503 genera.There are 1 species of phycophyta,3 species of fungoid,86 species of ferns,9 gymnosperms and 689 angiosperms.Four newly recorded species of Anhui plants were found:Dipalziopsis cavaleriana(Diplaziopsidaceae),Asplenium speluncae(Aspleniaceae),Adiantum juxtapositum(Adiantaceae)and Sedum amplibracteatum(Crassulaceae).The flora of 499 genera vascular plants in Yixian is divided into 15 types and 12 variants.The distribution of temperate zone is slightly higher than that of tropical components,and it has the characteristics of transition from tropical to temperate zone.The endemic distribution of China is large and the floristic characteristics are remarkable.Rare Chinese medicine culture in Yixian,only to survey the Dendranthema morifolium,Gardenia jasminoides,Trichosanthes kirilowii were planted,but lack of scientific management.The market of Chinese medicinal materials in Yixian is mainly three purchasing stations at Hongtan,Yuting and Hongxing.Medicinal materials are mainly sold to Bozhou,Jiangsu and Zhejiang provinces,including Polygonati Rhizoma,Polygoni Cuspidati Rhizoma et Radix,Acori Tatarinowii Rhizoma,Paris,Bletillae Rhizoma etc..Conclusion:In order to ensure the sustainable development of traditional Chinese medicine resources in Yixian,the development zones of Yixian’s Chinese medicine were studied according to the topography and spatial structure.The Yixian County development zone was divided into:karst geomorphic medicinal plant protection area,protection and utilization of medicinal plants in middle mountain areas,sustainable utilization of medicinal plants in low mountain areas,exploitation and utilization of medicinal plants in Hilly and plain areas.Combining the development zone,vigorously developing the cultivated medicinal materials,making rational use of the wild resources,expanding and planning the transaction the market of it as a whole.Using the advantages of Yixian ecological tourism,to promote the culture of traditional Chinese medicine and develop the medicinal plants used for medicine and food.
