基于数据挖掘方法探讨当代藏医使用我国青藏高原以外药材分布特点OA

Objective:To investigate the distribution patterns of Tibetan medicines by data mining,so as to promote the con-servation and sustainable development of Tibetan medicinal resources.Methods:Taking the Tibetan medicines recorded in the Dictionary of Chinese Ethnic Medicine as the primary data source,combined with literature including Chinese Tibetan Medicines,Chinese Tibetan Materia Medica,Medicinal Flora of Qinghai-Tibet Plateau,Flora of China,and Pharmacopoeia of China,a data-base of Tibetan medicinal species was established using Microsoft Excel,which contained characteristic information such as me-dicinal material name,family name,medicinal part and producing area.Statistical analysis was subsequently conducted on the pro-ducing area distribution data of Tibetan medicines.Results:A total of 3 027 Tibetan medicinal species were counted,including 2 469 botanical medicines,375 animal medicines and 183 mineral medicines.Among them,417 species(accounting for approxi-mately 13.78%of the total)were distributed outside the Qinghai-Tibet Plateau of China and applied in contemporary Tibetan medical practice,including 264 botanical medicines(63.31%),92 animal medicines(22.06%)and 61 mineral medicines(14.63%).The botanical medicines distributed outside the Qinghai-Tibet Plateau showed a highly concentrated distribution in Asia,particu-larly in Southern China and Southeast Asia,presenting a distinct gradient diffusion structure with the Qinghai-Tibet Plateau as the core and gathering in the southwest,and gradually decreasing in intensity around the periphery.The characteristics of medicinal parts of botanical and animal medicines were consistent with the geographical accessibility of resources,while animal and mineral medicines exhibited a widespread distribution pattern.Conclusion:The botanical and animal medicines distributed outside the Qinghai-Tibet Plateau and used in contemporary Tibetan medical practice are extensively distributed in Sichuan,Yunnan and Gansu Provinces of China,and present an Asia-centered distri-bution pattern globally.The introduction of exogenous medici-nal species has enriched the theoretical system and clinical me-dicinal varieties of Tibetan medicine,providing more options for medication and possibilities for drug combination in clini-cal treatment.
