The suitable distribution regions of medicinal clematis armandii in Sichuan province were extracted based on the suitable requirements of clematis armandii,comprehensive analysis and quantification on environmental indicators suitable forclematis armandii,following remote sensing (RS) and GIS spatial analysis,spatial database building and other technologies,extracted land use information.The results showed that regions suitable forclematis armandii were Gulin county,Xuyong county,Baoxing county and Tianquan county and other areas in Sichuan province.Among them,Gulin county and Xuyong county were the main distributed regions,which accounted for 23.2% and 25.4% of the total area,respectively.Through the comparison with the Chinese Materia Medica (CMM) Resource Database,this research result was basically coincided with census data from the Third National CMM.It also showed that RS and GIS technology were suitable for the investigation of suitable area of clematis armandii scientifically and feasibly.It improved the rational use of clematis armandii.It provided supporting information for rational planting of clematis armandii.It also of fered references for monitoring other wild herbs.

Objective To investigate the medicinal plant resources in Hongya County of Sichuan Province,so as to provide data support for the development,utilization,and protection of traditional Chinese medicine resources in Hongya County.Methods This study conducted a comprehensive investigation on the medicinal plant species in Hongya County using literature review,field investigation,interview investigation,sample plot investigation,and specimen collection.Results The findings revealed a total of 1748 species of medicinal plants in Hongya County,belonging to 808 genera and 185 families,the Compositae family had the highest proportion.Furthermore,the study identified 5 rare and endangered medicinal plants,14 species of wild plants under state key protection,9 species of wild medicinal materials under state key protection,185 species of traditional Chinese medicine listed in the 2020 edition of Chinese Pharmacopoeia of the People's Republic.Conclusion The medicinal plant resources in Hongya County are rich,but the utilization rate is low,and there is a large space for the industrialization development of traditional Chinese medicine.The general investigation results provide a reference for the rational development and protection of medicinal plant in Hongya County.

Sichuan Province is located across several major geomorphic units,such as the Qinghai Tibet Plateau,Hengduan Mountains,the Yunnan-Guizhou Plateau,Qinling Bashan Mountains,and Sichuan Basin.The complex ecological environment has created rich plant species.Based on the results of the fourth national survey of traditional Chinese medicine resources in Sichuan Province,according to the plant catalog in the,The results indicate that Sichuan has a total of 42 families,65 genera,and 116 species(including sub species)of medicinal plants under national key protection,there are 9 species such as lotus leaf fern under first level protection,and 107 species such as golden haired dog under second level protection.The distribution of rare and endangered medicinal plants in Sichuan Province has obvious regional characteristics,with the highest distribution in Leshan and Ganzi,and obvious vertical distribution.There are as many as 57 species distributed in high-altitude areas such as Ganzi Prefecture and Aba Prefecture.The endangered reasons for the key protected medicinal plants in Sichuan Province are mostly caused by human destruction and environmental damage.It is suggested to strengthen the protection of rare and endangered medicinal plant resources and develop and utilize them reasonably.

Objective To Provide basic information for the development of traditional Chinese medicine in the region by collating medicinal plant resources in Southern Sichuan Economic Zone.Methods The list was formed in Southern Sichuan Economic Zone by collecting and verifying Medicinal Plant Resources in 28 Counties(Districts)of the Southern Sichuan Economic Zone.The species composition,family structure,life type,threated degree of the medicine plants resources,the medicinal parts of key medicinal plants included,main cultivated medicinal herbs in the pharmacopoeia were statistically analysed for searching for the diversity of medicinal plant resources.Results The medicinal plant resources included 201 families,979 genera,2555 species.Herbaceous medicinal plants accounted for the largest proportion in both species and quantity.There are 270 species listed in the Chinese pharmacopoeia and 72 threatened and protected species among the medicinal plant resources.Conclusion The diversity of medicinal plant resources in the South Sichuan Economic Zone is prominent,and it can be reasonably developed,utilized,and protected.It is suggested to formulate effective protection measures for wild medicinal plant resources based on regional environmental characteristics,and rationally and sustainably develop and utilize high-quality medicinal plant resources with local characteristics.

Objective Investigate the types and reserves of key Chinese medicinal materials in Sichuan Province,and provide scientific basis for the sustainable utilization of traditional Chinese medicine resources in Sichuan Province.Methods Using a combination of field sample survey,market visit survey,and cultivation visit survey,we investigated the varieties and reserves of key Chinese medicinal materials in 183 county-level administrative regions in Sichuan Province.Results Sichuan Province has included 358 key varieties in the 2020 edition of the Chinese Pharmacopoeia,including 133 key medicinal materials under market investigation and 225 key medicinal materials under field investigation.The investigation discovered 325 key plant medicinal materials,14 key animal medicinal materials,14 key mineral medicinal materials,and 5 key fungal medicinal materials.We have completed a survey on the quantity and weight of 134 key Chinese medicinal materials,and calculated the reserve information of 134 key medicinal materials through the National Traditional Chinese Medicine Resource Census Database System.Conclusion Sichuan Province has abundant types of key traditional Chinese medicine resources,accounting for 51.3%of the total number of key varieties in the country.The resource reserves are large,exceeding 20 million tons,but some varieties of resources are severely damaged and urgently need to be protected.
